Description
Technical field:
The present invention relates to basement membrane technical fields, and in particular to the preparation method of high-weatherability printing basement membrane.
Background technique:
PVC is the white powder of amorphous structure, and the degree of branching is smaller, relative density 1.4 or so, glass transition temperature 77~90
DEG C, 170 DEG C or so start to decompose, and it is poor to the stability of light and heat, in 100 DEG C or more or through a long time exposure in sunshine, Jiu Huifen
It solves and generates hydrogen chloride, and further autocatalysis is decomposed, and causes to change colour, physical mechanical property also declines rapidly, is actually answering
Stabilizer be must be added in improve the stability to light and heat.
PVC floor has many good characteristics, such as moisture-proof, mould proof, waterproof, wear-resisting etc., old using being not easy indoors
Change and deforms.But the structural strength and weather resistance of PVC floor be not significant, when for example cold and hot, burn by extraneous adverse circumstances
When impact, PVC floor itself is easy breakage, influences its service performance.
The component part of PVC floor most critical is exactly the compound floor film in surface layer, plays incrustation, wear-resisting, weather-proof
Property, it is corrosion-resistant the effects of, have important influence to the service life of floor film.It is domestic at present that floor membrane technology is opened up not yet
Related research and development are opened, technological gap state is in.In consideration of it, company goes into overdrive that skill is unfolded to floor film key technology of preparing at present
Art tackling key problem, emphatically develops formula.
Summary of the invention:
Technical problem to be solved by the present invention lies in providing, a kind of self structure is stable, has to extraneous adverse circumstances relatively strong
The preparation method of the high-weatherability printing basement membrane of resistance.
The following technical solution is employed for the technical problems to be solved by the invention to realize:
The preparation method of high-weatherability printing basement membrane, comprising the following steps:
(1) by 80-100 parts of polyvinyl chloride resin, 1-5 parts of antioxidant, auxiliary agent 1-5 parts weather-proof, 10-15 parts of EVA, CPE 10-15
Part, 5-10 parts of organic tin stabilizer, 4-6 parts of MBS resin, 3-6 parts of in-lubricant, 4-6 parts of external lubricant, 2-4 parts of ACR auxiliary agent,
It is put into mixing machine and mixes；
(2) mixing, calendering, cooling, winding are carried out and is put in storage health 12 hours, printing basement membrane is formed；
(3) printing basement membrane is subjected to plastic film mulch, is fired in vulcanizer, semi-finished product is made；
(4) by semi-finished product health 12 hours；
(5) it is packed after detection is qualified and by warehousing finished products.
The weather-proof auxiliary agent the preparation method comprises the following steps: hydroxymethyl cellulose is add to deionized water, 30 DEG C of stirring 10-
Then 15min adds beta-hydroxy-butanoic acid and tetraethyl titanate, is heated to reflux state, insulated and stirred 0.5-4h is filtered while hot,
Decontamination is washed with deionized water, it is dry to constant weight.
The hydroxymethyl cellulose, beta-hydroxy-butanoic acid, tetraethyl titanate mass ratio be 4-6:3-5:0.01-0.02.
The antioxidant is selected from thio-2 acid dibasic acid esters or phosphite ester.
The in-lubricant is selected from one of paraffin, stearic acid, mineral oil.
The external lubricant is selected from one of polyethylene wax, low-molecular-weight polypropylene.
Using organic tin stabilizer, product is improved in the stability and heat-stable time of processing；MBS resin is as addition
Agent greatly improves the mechanical property of product；ACR auxiliary agent improves product flexibility (adaptability) of operation；In-lubricant reduces in process
Friction between molecule；External lubricant reduces the friction in process between polyvinyl chloride resin and equipment, improves demolding performace.
The degree of polymerization of the polyvinyl chloride resin is 1000-1300.
Further, the preparation method of the plastic film mulch liquid of plastic film mulch is carried out in the step (3) the following steps are included:
(1) modification of soft graphite: soft graphite is add to deionized water, and after mixing evenly, is added silane coupled
Agent and chain extender are heated to reflux state insulated and stirred 0.5-2h, filter while hot, impurity elimination is washed with deionized water in obtained solid
Then matter, 100-110 DEG C of drying to constant weight are sealed against being statically placed in -3-0 DEG C, 20-25 DEG C, 3-5 DEG C, the time stood every time
It is 30-50min；
(2) preparation of complex liquid: by Nano-meter SiO_22With Ni nanoparticle (OH)2Powder is added in dehydrated alcohol, ultrasonic disperse
30-50min；
(3) it mixes: modified soft graphite in step (1) being added in complex liquid, ultrasonic disperse 0.5-1.5h, i.e.,
Obtain plastic film mulch liquid.
The soft graphite, silane coupling agent, chain extender mass ratio be 3-5:0.3-0.5:0.02-0.04.
The Nano-meter SiO_22, Ni nanoparticle (OH)2Powder, dehydrated alcohol mass ratio be 10-15:6-10:60-80.
Further, the Ni nanoparticle (OH)2The concentration of powder is 1-8g/L, partial size 70-120nm.
The beneficial effects of the present invention are:
(1) present invention uses SiO2, Ni nanoparticle (OH)2For the plastic film mulch liquid that raw material is prepared, can be formed on printing basement membrane
Alloying layer composite construction has been obviously improved the weather resistance and structural strength of printing basement membrane, has there is it to extraneous adverse circumstances
Stronger resistance；
(2) under the action of chain extender the coupling between itself occurs for silane coupling agent, is adsorbed on the aperture of soft graphite
In, to be modified to soft graphite, film layer is firmly adsorbed on printing basement membrane and binding material, will not fall off
And cracking, further enhance the weather resistance and mechanical strength of printing basement membrane；
(3) the weather-proof auxiliary agent prepared using hydroxymethyl cellulose, beta-hydroxy-butanoic acid as raw material, because of the caking property of its own structure
It can reinforce the compactness on film layer and floor with reactivity, while weather-proof auxiliary agent is added in printing basement membrane, can be improved each
Connectivity between raw material, and then promote the weather resistance of printing basement membrane.
