High-temperature-resistant plastic product and preparation method thereof

Abstract

The invention discloses a high-temperature-resistant plastic product and a preparation method thereof, and belongs to the field of plastic products. A high-temperature-resistant plastic product comprises a thermoplastic polymer, a filler, a supplement, a stabilizing reagent, a foaming agent and chemical high-temperature heat-insulating particles. The thermoplastic polymer comprises polytetrafluoroethylene, low density polyethylene, polypropylene and polyimide. The filler comprises clay, talc, sodium silicate powder and calcium carbonate powder. The plasticizer comprises aliphatic dibasic acidester and phosphate. In addition to basic heatproof measures, a chemical reaction for absorbing a lot of heat is introduced to increase thermal loss and heat transmission resistance of the material. Thereby, heat for internal transfer is reduced and the speed of heat transmission is lowered, and then the plastic product has excellent and long-acting high temperature resistance. Meanwhile, a more stable high-temperature-resistant substance can be generated through a chemical endothermic reaction to be attached to the inside and surface of the plastic product, and then heat resistance and flameresistance of the plastic product are further improved.

Description

technical field [0001] The invention relates to the field of plastic products, more specifically, to a high-temperature-resistant plastic product and a preparation method thereof. Background technique [0002] Plastic products are a general term for household and industrial products processed with plastic as the main raw material, including injection molding, blister and other products that use plastic as raw material. Plastic is a class of plastic synthetic polymer materials. The production of plastic products generally includes plastic ingredients, molding, machining, joining, modification and assembly. The last four processes are carried out after the plastic has been formed into finished products or semi-finished products, also known as plastic secondary processing. [0003] There are more than 30 methods of plastic molding, and its choice is mainly determined by the type of plastic (thermoplastic or thermosetting), the initial shape, and the shape and size of the prod...

AI Technical Summary

Problems solved by technology

[0004] Compared with other material products, plastic products have many advantages such as low manufacturing cost, durability, waterproof, light weight, and strong corrosion resistance, but at the same time, they also have disadvantages such as difficulty in recycling, flammability, and poor heat resistance. Most of the products are added with a variety of additives to promote the plastic to improve the processability, physical, chemical and other functions of the base material and increase the physical and chemical properties of the base material, thereby improving various properties of the plastic, such as adding heat stabilizers. Heat resistance of plastic products

[0005] The heat resistance of existing plastic products still has great defects, and it is easy to deform under high temperature, which makes it impossible to use normally
