Description
Technical field
The invention discloses a kind of hot melt adhesives, specifically, being that one kind can the low VOC of irradiation-induced degradation high temperature resistant and low gas
Taste oil resistant hot melt adhesive, belongs to field of adhesive technology.
Background technique
In motor-car, high-speed rail, automobile, preventing for the sealing of the joining place between the harness such as car is waterborne, and master is engine
Cabin usually requires to be bonded using a large amount of hot melt adhesive at car body harness internal cohesion.However, having in automobile engine compartment
Usually there are a large amount of grease stains in total group of environment of machine oil, so that influencing service life, seal request is unable to satisfy, to automobile
Whole safe operation have huge hidden danger.
Melten gel stick currently on the market is mostly polyamide (PA), ethylene-vinyl acetate copolymer (EVA), rosin, bonding
Agent, antioxidant, viscosity adjustment etc. are blended.Sizing operation will be carried out after product heating melting, but is glued in heating melting
In the process, volatile organic compounds generation is had, it may be assumed that escaping gas can cause damages to human body.Especially use
In roof of the vehicle stick, there are also harness sealings in automobile body to use, and for people during driving, the most of the time is closed
In space, if in the case that car VOC is exceeded, injury can be generated to human body.
In car gage in 2017 to the VOC value of vehicle material and it is odor profiles carried out stringent regulation, mainly
To vehicle operation personnel, the health of passenger poses a serious threat interior air quality；Therefore vehicle interior gas is waved
The situation of hair needs strict control, green, environmental protection, and health has been very urgent.
Summary of the invention
In view of the above-mentioned problems, the object of the present invention is to provide it is a kind of can satisfy irradiation after the bonding force of product meet need
It asks, and reduces the content of volatile matter, the hot melt adhesive of excellent oil resistance.
In order to solve the above technical problems, technical solution provided by the invention is such that
One kind can the low VOC of irradiation-induced degradation high temperature resistant and low smell oil resistant hot melt adhesive, including following components in parts by weight:
0-65 parts of kymene, 20-32 parts of polyethylene, 27-45 parts of rubber elastomer, 0.5-10 parts of polyacrylate rubber, antioxygen
1-1.5 parts of agent, 0.5-2.5 parts of curing agent.
Further, the above-mentioned low VOC of irradiation-induced degradation high temperature resistant and low smell oil resistant hot melt adhesive, further include polyolefin
3-10 parts of elastomer.
Further, the above-mentioned low VOC of irradiation-induced degradation high temperature resistant and low smell oil resistant hot melt adhesive, the polyolefin
Elastomer is metallocene-polyolefin.
Further, the above-mentioned low VOC of irradiation-induced degradation high temperature resistant and low smell oil resistant hot melt adhesive, the rubber bullet
Property body be one of polyisobutene, polyisoprene, butyl rubber, EP rubbers or any combination.
Further, the above-mentioned low VOC of irradiation-induced degradation high temperature resistant and low smell oil resistant hot melt adhesive, the antioxidant
For thiophenol kind antioxidant, Hinered phenols antioxidant, arene antioxidant, preferably 2,6- di-tert-butyl-4-methy phenol.
Further, the above-mentioned low VOC of irradiation-induced degradation high temperature resistant and low smell oil resistant hot melt adhesive, the curing agent
For N- dodecyl succinic anhydride or one of alkenyl succinic anhydride or nonyl succinic anhydride.
Compared with prior art, the technology technical solution that this law provides has following technological merit again:
1, the hot melt adhesive of irradiation to crack type provided by the invention is using the viscoelastic for keeping adhesive high in process
Property, promote product not occur excessive glue, the situation of trickling in use in this way；After high-energy electron accelerator irradiation, product
The just section cracking of part high molecular weight material, increases the flowing row of whole hot melt adhesive, and can satisfy and prepared using this product
Double-walled heat-shrinkable T bush seal the ability of a plurality of harness simultaneously.
2, technical solution provided by the invention uses the highly viscous polyamide product and rubber body elasticity itself having
Body, polyolefin elastomer, the bulk strength of the products such as polyolefin plastomers increase product, heatproof high temperature performance, acid and alkali-resistance,
The harshness use environment such as oil resistant, while there is the performance of irradiation to crack.
3, technical solution provided by the invention uses low smell, production provided by the invention in material selection and preparation process
Product are mainly used in automobile, rolling stock, ship, aviation, wait harness to seal, have both been able to satisfy a plurality of line of a seal of tube now
Beam, and 135 degrees Celsius of above high temperature of rank are able to satisfy, and acid or alkali environment under relatively severe condition than using.
4, technical solution provided by the invention can be cracked in the case where high-energy electron accelerator irradiates and be generated free radicals,
And embody good adhesive property to material, and do not drip after 158 DEG C of 168h, low VOC, oder levels 3.0 with
Under, meet to industry to the environmentally protective demand of product.
To sum up, hot melt adhesive provided by the invention is mainly used in automobile, rolling stock, ship, aviation etc. is close
It seals in the sealing of harness, that is, is able to satisfy sealing demand of the harness under high temperature, environment, and be able to satisfy low VOC, low smell is wanted
It asks, to environmentally protective, human health has important meaning.
