Description
Technical Field
The invention belongs to the field of high polymer materials, and particularly relates to alcohol-scratch-resistant transparent nylon and a preparation method thereof.
Background
Transparent nylon is an amorphous or microcrystalline thermoplastic nylon with light transmittance up to 92% and superior to PC and glass. Transparent nylon is resistant to dilute acid and alkali, aliphatic hydrocarbon, aromatic hydrocarbon, esters, ethers, oil and fat, is superior to PC and PMMA in environmental stress cracking resistance, can be widely applied to the fields of automobiles, electronic appliances, machinery, optics, sports and the like, but the traditional transparent nylon is poor in alcohol tolerance and limited in application. In the optical field, transparent nylon is often used for sunglasses, glasses frames and lenses of intelligent watches, friction can be generated between the parts and skin, the cosmetic on the skin contains alcohol substances, after long-time friction, the haze of alcohol-intolerant transparent nylon is increased, the light transmittance is poor, the mechanical property of the transparent nylon is also poor, the use feeling of consumers is affected, and therefore, the use value of the transparent nylon can be further improved by improving the alcohol resistance of the transparent nylon. Patent CN101613527A discloses an alcoholysis-resistant nylon composite material and a preparation method thereof, wherein the composite material comprises 55-70% of nylon, 25-35% of short glass fiber, 0.2-4.0% of glass fiber exposure prevention regulating auxiliary agent, 0.1-2.0% of nucleating agent, 1.0-3.0% of coloring agent, 0.1-2.0% of heat stabilizer and 0.1-2.0% of alcoholysis-resistant auxiliary agent; the preparation method comprises the steps of adding the preferable components into a high-speed mixer for uniform mixing, putting into a double-screw extruder, extruding and granulating. The alcohol resistance of the glass fiber modified nylon is derived from the effects of silane coupling agent modified short glass fiber and alcohol-resistant auxiliary agent hexamethylphosphoric triamide, the hexamethylphosphoric triamide has no redundant amine group to react with nylon end groups, only the blending effect is achieved through screw extrusion, the alcohol-resistant auxiliary agent is dissociated in the glass fiber modified nylon, and the alcohol-resistant auxiliary agent gradually migrates to the surface and is lost along with the time, so that the alcohol resistance of the product is reduced along with the time. Patent CN108003613A discloses an alcohol-resistant nylon and a preparation method thereof, wherein the alcohol-resistant nylon is prepared from 90-98 parts of nylon 1012/12I copolymer resin, 1-7 parts of multifunctional epoxy resin and 1-3 parts of cross-linking agent. According to the method, benzene rings are introduced in a polymerization stage to improve the alcohol resistance of a nylon body, and then the alcohol resistance of the nylon is further improved through crosslinking, but the selected crosslinking agents are dicumyl peroxide DCP and tri-functional aziridine, according to a reaction principle, the multi-functional epoxy resin and the tri-functional aziridine can react with terminal carboxyl groups of nylon chain ends to form a micro-crosslinking system, and the dicumyl peroxide DCP is heated to form free radicals, so that alkane on the nylon chain is easily attacked to cause excessive crosslinking or decomposition, and the reaction system is unstable.
In summary, the alcohol rub resistance of the existing transparent nylon needs to be further improved.
