Problems solved by technology

TPEE has good anti-swelling performance and anti-permeability to most organic solvents, fuels and gases, but its permeability to fuel is only 1 / 3~ of oil-resistant rubber such as neoprene, chlorosulfonated polyethylene, and nitrile rubber. 1 / 300, TPEE has poor hot water resistance
[0004] In the prior art, TPEE is only attached and molded with AB, PC or PVC, and the integral molding effect is poor
The mainstream of PC alloy materials is PC / ABS products, but PC has poor processing fluidity, is prone to stress cracking, is sensitive to notches, is easy to wear, and has poor chemical resistance; and PC / ABS products have low impact and poor low temperature resistance. Use in cold weather conditions, the use of the environment has limitations

The material is widely applied to the industry of electronics and automobiles.

Description

technical field [0001] The invention relates to a PC / TPEE alloy, in particular to a PC / TPEE alloy with high fluidity and low temperature resistance and a preparation method thereof. The alloy is widely used in automobile industry, electronic and electrical industry, industrial manufacturing, electric tools, and life Supplies etc. Background technique [0002] TPEE (thermoplastic polyester elastomer) is a block copolymer containing polyester hard segments and polyether soft segments. Among them, the polyether soft segment and the uncrystallized polyester form an amorphous phase, and the polyester hard segment partially crystallizes to form a crystalline microdomain, which acts as a physical crosslinking point. TPEE has the elasticity of rubber and the strength of engineering plastics; the soft segment gives it elasticity, making it like rubber; the hard segment gives it processing properties, making it like plastic; compared with rubber, it has better processing properties a...
