Halogen-free glass fiber reinforced PC and preparing technique thereof

Abstract

The present invention relates to an organic polymer composite, particularly to a halogen-free glass fiber reinforced polycarbonate (PC) and a preparing technique thereof. The halogen-free glass fiber reinforced PC consists of the following constituents in a ratio by weight: 47.5 to 95% of PC, 5 to 35% of environmental protection glass fiber, 0.1 to 2.0% of antioxidant, 1 to 3.0% of stone mastic asphalt (SMA), 0.1 to 2.0% of grafted polyethylene (PE) and 1.3 to 5.5% of other auxiliaries. The halogen-free glass fiber reinforced PC and the preparing technique have the advantages that comprehensive mechanical properties are excellent, the PC does not contain halogen, no fibers are exposed outside the product, and production and procurement are convenient. The present invention changes the conditions that users always need to reduce the requirements for certain aspects, and meanwhile meets all the other environmental protection requirements. Thus, the comprehensive competitive power is improved.

Description

technical field [0001] The invention relates to an organic polymer composite material, and more specifically relates to a halogen-free glass fiber reinforced PC and a preparation method thereof. Background technique [0002] PC is an amorphous, odorless, odorless, non-toxic and transparent thermoplastic polymer. It has comprehensive mechanical, thermal and electrical properties, especially high impact toughness, small creep, stable product size, and excellent high-temperature electrical properties. performance. As an engineering plastic with excellent comprehensive performance, PC is widely used in mechanical, electronic, electrical, lighting, building safety and medical equipment in various fields of national economy. The use of glass fiber reinforced PC can greatly improve its mechanical strength and long-term service temperature, thereby greatly expanding the scope of application, and can replace wood and metal in many fields. At present, for various reasons, developed ...

Problems solved by technology

Therefore, it has caused serious troubles to many export enterprises in my country.

However, the glass fiber reinforcement currently seen in the market is either unable to guarantee that it does not contain halogens, resulting in limited environmental protection, or it is expensive and highly dependent, or the mechanical properties are not excellent enough, and the appearance of the finished product is not beautiful, or It is the disadvantage that the impact strength is not high, etc.
