Abstract
Description
The present invention relates to an epoxy-asphalt preprocessing composition for road pavement, and more particularly, to a preprocessing composition having improved compatibility and physical properties by using ethylene vinyl benzoate as a compatibilizing agent in an epoxy resin and an asphalt.
Generally, the bottom surface of the road or bridge is pretreated with resin pretreatment agent before paving with ascon. The pretreatment agent should be excellent in adhesion, water resistance, shock absorption, crack resistance, cold resistance, heat resistance, and economy, since it modifies the properties of the bottom and connects the bottom and top of the surface.
As the pretreatment agent, usually thermoplastic resin or thermosetting resin is used. Examples of the thermosetting resin used as the pretreatment agent include an epoxy resin and a urethane resin. Examples of the thermoplastic resin used as a pretreatment agent include a modified epoxy resin, a modified urethane resin, a petroleum resin, and an asphalt. In recent years, a mixture of a thermosetting resin and a thermoplastic resin has been widely used as a pretreatment agent.
As described above, the pretreatment agent for road pavement should exhibit excellent performance in terms of water resistance, crack resistance, adhesion, impact absorbability and economy. One of the excellent combinations satisfying the above conditions is a mixture of epoxy resin and asphalt.
However, the epoxy resin in this combination is generally excellent in adhesion but has a disadvantage in that it lacks flexibility. In addition, asphalt is heat-soluble in summer and exhibits sufficient plasticity, but it is brittle in winter and weak in bending and impact. In order to overcome these disadvantages, a rubber elastomer is generally mixed as a third supplement. Examples of the elastomer used here include butadiene rubber (BR), styrene-butadiene rubber (SBR), styrene-butadiene-styrene (SBS), ethylene vinyl acetate (EVA), acrylonitrile butadiene rubber (NBR) ). Among them, low-priced ethylene vinyl acetate (EVA) is mainly used.
As described above, the epoxy-asphalt mixture is often used as a pretreatment agent for road pavement. However, this mixture has a problem in that cracking occurs on the road due to insufficient bending resistance and impact resistance due to brittleness in winter. To solve this problem, ethylene vinyl acetate (EVA), which is a cheap rubbery elastomer, is added to the mixture. Ethylene vinyl acetate (EVA) has poor compatibility with epoxy resin and asphalt, .
The solubility parameter (MPa 1/2 ) of each raw material used in the present invention is asphalt 8.8 to 9.0, epoxy resin 9.7 to 10.9, and ethylene vinyl acetate (EVA) 10.2 to 10.4.
The smaller the difference in solubility index is, the better the compatibility between the compounds. Ethylene vinyl acetate has a large difference in solubility index with other raw materials, which causes poor separation between the epoxy resin and asphalt, causing phase separation between the binder materials, Problems such as generation, strength failure, road surface off, crack occurrence, hardening failure, durability defect, and the like occur.
The inventors of the present invention have found that ethylene vinyl acetate (EVB) can be produced by reacting ethylene vinyl acetate with benzoic acid to save time and efforts to solve the above problems that occur when ethylene vinyl acetate is added as an compatibilizing agent to an epoxy- , ethylene vinyl benzoate), and using this as a compatibilizer, the above problems were solved, leading to the present invention. The present invention will be described more specifically by replacing the acetate group in the ethylene vinyl acetate molecule with a benzoate group through acidolysis to obtain ethylene vinyl benzoate having a solubility index of 9.2, The above problems are solved by using it as a compatibilizer. The production mechanism of ethylene vinyl benzoate (EVB) is shown in Fig.
The epoxy-asphalt pretreatment composition of the present invention comprises 40-60% by weight of epoxy resin, 30-50% by weight of asphalt and 5-15% by weight of compatibilizer.
The epoxy resin is composed of 35-75 wt% of the main epoxy resin, 10-25 wt% of the reactive diluent, and 5-40 wt% of the curing agent. Users can use themes, reactive diluents, hardeners, asphalt, and compatibilizers by mixing them into two groups as appropriate. During the mixing, the curing reaction of the epoxy resin as shown in Fig. 2 occurs. The curing reaction occurs through the reaction of the epoxide of the epoxy resin and the reactive diluent with the amino group of the curing agent.
The following describes each of the raw materials used to make the epoxy-asphalt pretreatment composition in the present invention.
A liquid epoxy resin was used as the epoxy resin. The epoxy resin accounts for 40-60 wt% of the total mixture. When the epoxy resin content is less than 40 wt%, the continuous phase of the epoxy resin is not formed, and the tensile strength and hardness remarkably decrease. On the other hand, when the content exceeds 60% by weight, the flexibility and adhesive property are improved, but the asphalt content is relatively decreased and the initial strength and hardness are lowered because it takes time to cure the epoxy resin. The lower layer support force of the road on which the heavy vehicle travels is weakened, so that the slip of the upper asbestos layer may occur.
A bisphenol A type epoxy resin and / or phenol novolac type epoxy resin having an equivalent weight of 150-250 and having at least two reactive epoxides in the molecule was used as the epoxy resin. If the equivalence of the epoxy resin is too large, the fluidity of the epoxy resin and the asphalt mixture deteriorates, and the mixed solution can not be easily injected. An appropriate amount of the main epoxy resin is 35-75 wt% of the total epoxy resin. If the epoxy resin base is used in an amount of less than 35% by weight, the mechanical strength is weakened. If the epoxy resin base is used in excess of 75% by weight, the coating film becomes stiff. The epoxy resin has an aromatic structure such as bisphenol A type or novolac phenol, and thus has a higher affinity for aromatic solvents than an aliphatic solvent, so that it is more soluble in aromatic solvents.
Specific examples of usable bisphenol A type epoxy resins include YD 115, 127, 128 and 134 manufactured by Kukdo Chemical Co., Ltd., DER 321, 324, 330, 331, 332 and 334 manufactured by Dow Chemical Co., Epon 815, 827, 828, 834 and the like, but the disclosure is not limited to the listed products.
DEN 431, 438 and 439 of Dow Chemical Co., Ltd. and YDPN-631, 636 and 637 of Kukdo Chemical Co., Ltd. are the specific product names of the novolak phenol type epoxy resins which can be used. These products are novolak phenol type But is not limited thereto.
As a reactive diluent, low viscosity epoxy resins with an equivalent weight of 130-200 and having at least one epoxy in the molecule were used. In general, those having a small number of functional groups, a small molecular weight, a low viscosity, and a good fluidity were used. They serve to lower the viscosity of the mixture, control the curing time, impart flexibility to the cured product, and control the strength and adhesion.
A suitable amount of the reactive diluent is 10-25% by weight of the epoxy resin component. When less than 10% by weight of the reactive diluent is used in the epoxy resin component, flexibility is not obtained. If the reactive diluent is used in an excess amount exceeding 25% by weight, the cured product becomes weak and the strength is significantly decreased.
Reactive diluents that can be used include polyether-modified epoxy, polyester-modified epoxy, urethane-modified epoxy, and vinyl resin-modified epoxy resins having at least one reactive epoxide in the molecule of molecular weight 200-2000. More preferably, a polyether-modified epoxy having two reactive epoxides in the molecule of molecular weight 300-1000 is used. Generally, when a chain having a short chain length is used, the fluidity is improved and the coat is hardened. On the other hand. If the chain length is long, the fluidity is bad but the flexibility of the cured product is improved. The reactive diluent is an epoxy structure as described above, so it is more soluble in aromatic solvents than aliphatic ones.
Examples of commercially available reactive diluents include phenylglycidyl ether (PGE), n-butyl glycidyl ether (n-BGE), styrene oxide (SO), allyl glycidyl ether (AGE) Neopentylglycidyl ether (NPGDE), LGE, PG-207P, and the like, but the present invention is not limited thereto.
Amines were used as curing agents for epoxy resins. The curing reaction mechanism of the epoxy resin by the amine is shown in Fig. The curing reaction of the epoxy resin occurs mainly by the reaction between the epoxides of the subject and reactive diluent and the amino groups of the curing agent. However, the actual curing reaction is a complex reaction involving the reaction between epoxide-epoxide and epoxide-hydroxyl groups. The curing reaction is ionically promoted by amines.
The epoxy-asphalt pretreatment composition of the present invention is sprayed on the road at a mixture temperature of 100-130 DEG C using a high-pressure sprinkler in the field. For ample work, a pot life of 10-20 minutes at 100-130 ° C should be ensured after mixing. In addition, when the epoxy-asphalt pretreatment composition is sprayed from a sprayer and the road surface is wetted, it must be fast cured within 2-3 hours, so that it can be a pretreatment agent for the aspon packaging to meet the purpose of the desired purpose. Good curing agents for this purpose include polyamines, imidazoles, and modified amines. More preferably, a polyamine having 15-25 carbon atoms in the molecule and having at least one reactive amino group is used. Polyamines include cyclohexylamine, laurylamine, pentadecylamine, hexadecylamine, oleylamine, and the like. Modified amines include Jeffamine D-230, D-2000, D-400, and T-403 manufactured by Kukdo Chemical Co., Imidazolo is 2MZ, 2PZ, 2PZ-PW and C17Z of Ildong Chemical Co., Ltd. This is only an example and does not limit the scope of claims. The preferred amount of the curing agent used is 5-45 wt% of the total epoxy component.
The proper amount of each curing agent is 30-45 wt% of polyamine, 20-30 wt% of modified amine, and 5-10 wt% of imidazole in the total epoxy resin. Generally, when curing agent is used more than the reference amount, the curing time is accelerated. However, excessive use of the hardener will result in incomplete curing, which will weaken the coating and deteriorate the water resistance. If too little curing agent is used, incomplete curing will occur or the cured product will become stiff. Most amines are more soluble in ketone or aromatic solvents than alcohols.
Asphalt is a remnant that remains as a final product in the distillation of petroleum, and exhibits excellent waterproofness, extensibility and adhesiveness. Examples of the asphalt usable in the present invention include straight asphalt, blown asphalt, colored asphalt, and modified asphalt. Straight asphalt has AP-3 and AP-5, AP-3 is soft and AP-5 is hard. The criterion for universal classification is penetration, AP-3 penetration is 80-100, and AP-5 penetration is 60-80. Blow asphalt is oxidized by blowing air (oxygen) into straight asphalt and has higher hardness and better weatherability than straight asphalt. Colored asphalt removes black components from straight asphalt and is colored with a specific color. Modified asphalt improves its properties by dissolving resins and elastomers in straight asphalt. The above various asphalt can be obtained from Honsung Industry Co., Ltd. or Korea Petroleum Co.,
A suitable amount of asphalt is 30-50 wt.% In the pretreatment composition. When the asphalt is used in an amount of less than 30% by weight, the initial solidification time of the mixed solution is slow and the adhesiveness is insufficient so that the ascon layer can not be sufficiently adhered. On the other hand, when the asphalt is used in excess of 50%, the initial cohesion is high, but the final state of the solidified material is brittle at low temperature, and the road may collapse due to overheating during cold winter.
As far as the solubility of asphalt is concerned, asphalt is composed of aliphatic alkanes, alkenes, cyclic compounds and other small amounts of inorganic compounds and has excellent solubility in aromatic solvents such as xylene and toluene.
In the present invention, ethylene vinyl benzoate (EVB) was used as a compatibilizer. Ethylene vinyl benzoate was prepared by replacing the acetate group of ethylene vinyl acetate with a benzoate group through an acid decomposition reaction. More specifically, as shown in FIG. 1, benzoic acid was added to ethylene vinyl acetate at a ratio of 100: 40 to 100: 60 (w / w) together with the catalyst, followed by condensation reaction at 150-170.degree. C. for three hours. The termination of the reaction was defined as the end point when more than 80% of the acetic acid of ethylene vinyl acetate was replaced with benzoic acid, and the termination point was determined by the content of acetic acid produced by condensation.
The benzoate content in the reacted ethylene vinyl benzoate was 31-57% (w / w).
Ethylene vinyl acetate used in the reaction for producing ethylene vinyl benzoate in the present invention has a melting point of 100 占 폚 or less and a vinyl acetate (VA) content of 50% or less. EVA-1519 (VA content 19%), 1520 (VA content 19%), 1528 (VA content 28%), 1529 (VA content 28%) and 1533 (VA content 28%) were used as the ethylene vinyl acetate which can be used. 33%), and 1540 (40% of VA content). However, the present invention is not limited thereto.
Examples of the reaction catalyst used in the reaction for producing ethylene vinyl benzoate include sulfuric acid, sulfonic acid, boron trifluoride (BF 3 ), metallic soap of tin and zinc, and mercury salt. As commercially available catalysts, methyl sulfonic acid of Daesung Methanol Co., p-toluene sulfonic acid of P-TSA of Songwon Industrial Co., Fascat 4102 (organotin compound of M & T) But is not limited thereto. A suitable amount of catalyst is 0.10-0.15% (w / w) of the total composition weight.

According to the present invention, substitution of an acetate group of an ethylene vinyl acetate used as a compatibilizing agent in an epoxy-asphalt preprocessing composition with an aromatic benzoate group leads to a longer molecular chain and a lower polarity, thereby improving the compatibility between the epoxy- It has shown various excellent improvement effects in terms of physical properties such as prevention, increase of flexibility, increase of strength and improvement of adhesion.

Next, the transportation and application of the pretreatment agent composition mixture of the present invention will be described.
The epoxy resin used in the present invention is a two-component type which is cured when an epoxy resin having an epoxide is mixed with an amine having an amino group. In the present invention, a mixture containing an epoxide is referred to as a subject, and a mixture containing an amino group is referred to as a curing agent. The subject was made by mixing a main epoxy resin with a reactive diluent in the molecule and a reactive diluent, followed by a compatibilizing agent. The curing agent was made by mixing asphalt with amines with reactive amino groups. In some cases, however, the main epoxy resin, the reactive diluent and the asphalt may be mixed to form a base, and the amine and compatibilizer may be mixed to form a curing agent. In the present invention, two kinds of tanks made as shown in Fig. 3 are separately provided with a main body and a curing agent.
Prior to spraying, the subject and curing agent were pre-heated to 50-150 ° C in the tank, respectively. The subject and the curing agent were transferred at a weight ratio of 60:40 to 40:60, respectively, and mixed in a mixing tank for 1 to 2 minutes. The mixture was then transferred to a pressure pump and sprayed at a pressure of 40 kg / cm 2. The temperature of the mixed solution was 100-130 캜. The mixing time of the mixture after mixing was 10-20 minutes at room temperature. The shape and structure of the specific transportation vehicle are shown in Fig. Since the vehicle of the present invention uses a PD meter capable of operating at a high temperature and a high viscosity, precise metering is possible as compared with a conventional tipping meter, and since the subject and the curing agent are sufficiently mixed and injected in the mixing tank, uniformity of the mixture, The physical properties can be maintained constant and the pressure can be uniformly applied to the road surface at a constant pressure by using the pressurizing pump.
