Problems solved by technology

[0002] As one of the five general-purpose engineering plastics, polyethylene terephthalate (PET) engineering plastics has outstanding toughness, aging resistance, creep resistance, friction and wear resistance, and is comparable to the widely used PBT polyester engineering plastics at present. Compared with PET, PET has the advantages of high heat resistance temperature, easy access to raw materials, large output, and low price. However, due to its own molecular structure characteristics, PET has slow crystallization speed, imperfect and uneven crystallization, resulting in long injection cycle during processing. Due to post-crystallization, the product is prone to warping, rough surface, poor impact resistance and heat and humidity resistance, etc., which seriously limits its application as engineering plastics.

Abstract

The invention discloses an inflaming-retardant enhanced engineering plastic formula. The formula is prepared from, by weight, 1155 to 1157 parts of polyethylene terephthalate (PET), 245-255 parts of melamine pyrophosphate hydrochloride (MPP), 590-610 parts of glass fibers, 8-12 parts of talcum powders, 28-32 parts of poly (butylene succinate) (PBS) and 3-5 parts of antioxidants. The melamine pyrophosphate hydrochloride (MPP) added in the inflaming-retardant enhanced engineering plastic formula plays both the role of inflaming-retarding and the role of nucleating to replace part of functions of a nucleating agent. The tensile strength and the bending strength are obviously increased after the nucleating agent PBS is added, so that the engineering plastic with high performances such as inflaming-retard, strength and the like are obtained.

Description

technical field [0001] The invention relates to the technical field of engineering plastics, in particular to a flame-retardant reinforced engineering plastic formula. Background technique [0002] As one of the five general-purpose engineering plastics, polyethylene terephthalate (PET) engineering plastics has outstanding toughness, aging resistance, creep resistance, friction and wear resistance, and is comparable to the widely used PBT polyester engineering plastics at present. Compared with PET, PET has the advantages of high heat resistance temperature, easy access to raw materials, large output, and low price. However, due to its own molecular structure characteristics, PET has slow crystallization speed, imperfect and uneven crystallization, resulting in long injection cycle during processing. Due to the post-crystallization of the product, it is easy to warp, the surface is rough and dull, and the impact resistance and moisture resistance are poor, which seriously li...
