Problems solved by technology
Creep resistance, fatigue resistance, good friction resistance, low wear and high hardness, with the greatest toughness among thermoplastics; good electrical insulation performance, little affected by temperature, but poor corona resistance
Non-toxic, weather resistance, good stability against chemicals, low water absorption, resistant to weak acids and organic solvents, but not resistant to hot water soaking, not alkali resistant
The glass transition temperature of PET resin is high, the crystallization speed is slow, the molding cycle is long, the molding cycle is long, the molding shrinkage rate is large, the dimensional stability is poor, the crystallized molding is brittle, and the heat resistance is low; the traditional production of automobile distributor Most of the covers are reinforced with nylon PA66 to improve the thermal deformation temperature and other bad properties of PET. However, cracks and damages often appear on the cover of the automobile distributor, which affects the normal use of the car and is likely to cause safety hazards. Therefore, a new, high-performance The distributor cover is necessary for the development of the automotive industry

The invention discloses an enhanced automobile distributor cap. The enhanced automobile distributor cap comprises the following raw materials by weight: 90 to 100 parts of a PET resin, 10 to 20 parts of nylon PA66, 1 to 2 parts of triethylene glycol di-2-ethylhexoate, 3 to 4 parts of meerschaum powder, 4 to 6 parts of polyimide, 2 to 3 parts of anhydrous calcium chloride, 0.8 to 1 part of tetra-[beta-(3,5-di-tert-butyl-4-hydroxycyclohexyl phenyl)propionic acid]pentaerythritol ester, 1 to 2 parts of a auxiliary agent, 1 to 2 parts of sodium tripolyphosphate, 1 to 2 parts of diethanolamine, 0.2 to 0.3 part of dimethicone and 1 to 2 parts of (3-aminopropyl) triethoxysilane. According to the invention, the component nylon is added into the raw materials used for production, so strength and high temperature resistance of the automobile distributor cap are improved.
Description
technical field [0001] The invention mainly relates to a distributor cover, in particular to a reinforced automobile distributor cover. Background technique [0002] PET is a milky white or light yellow highly crystalline polymer with a smooth and shiny surface. Creep resistance, fatigue resistance, good friction resistance, low wear and high hardness, with the greatest toughness among thermoplastics; good electrical insulation performance, little affected by temperature, but poor corona resistance. Non-toxic, weather resistance, good stability against chemicals, low water absorption, resistant to weak acids and organic solvents, but not resistant to hot water soaking, not alkali resistant. The glass transition temperature of PET resin is high, the crystallization speed is slow, the molding cycle is long, the molding cycle is long, the molding shrinkage rate is large, the dimensional stability is poor, the crystallized molding is brittle, and the heat resistance is ...
