Description
Technical field
The present invention relates to engineering material, hydrolyze PBT composite more particularly to a kind of high temperature resistant.
Background technique
Polybutylene terephthalate (PBT) (PBT resin) has excellent abrasion resistance, heat resistance, chemical resistance, electricity
The characteristics such as insulating properties and mechanical strength height, therefore, the 1960s has just started the application and development as engineering plastics.At present
PBT engineering plastics have been applied to the industries such as automobile, motor, electronics, household electrical appliance and machinery.
But find in actual production, existing PBT resin contains ester group, it is caused to exist in higher temperature and moisture
Under conditions of to hydrolyze it is very sensitive, especially become apparent from 160 DEG C or more hydrolysis, lead to PBT material physical machine
Tool performance declines rapidly, this disadvantage limits application of the PBT under hygrothermal environment.
Summary of the invention
Goal of the invention: to solve the deficiencies in the prior art, a kind of high-temperature resistant water that can be used for a long time in hygrothermal environment is provided
Solve PBT composite.
Technical solution: a kind of high temperature resistant hydrolysis PBT composite, according to the number of parts by weight, including the following raw material: PBT
40-60 parts of resin, 5-15 parts of PMMA resin, 0.5-2 parts of heat stabilizer, 3-8 parts of toughener, 10-15 parts of polypropylene, auxiliary agent 1-3
Part, 2-5 parts of pelletted pitch, 2-8 parts of talcum powder, 1-2 parts of anti-hydrolysis agent.
Including the following raw material preferably, according to the number of parts by weight: 40 parts of PBT resin, 5 parts of PMMA resin, heat stabilizer
0.5 part, 3 parts of toughener, 10 parts of polypropylene, 1 part of auxiliary agent, 2 parts of pelletted pitch, 2 parts of talcum powder, 1 part of anti-hydrolysis agent.
Including the following raw material preferably, according to the number of parts by weight: 60 parts of PBT resin, 15 parts of PMMA resin, thermostabilization
2 parts of agent, 8 parts of toughener, 15 parts of polypropylene, 3 parts of auxiliary agent, 5 parts of pelletted pitch, 8 parts of talcum powder, 2 parts of anti-hydrolysis agent.
Including the following raw material preferably, according to the number of parts by weight: 50 parts of PBT resin, 10 parts of PMMA resin, thermostabilization
1 part of agent, 5 parts of toughener, 12 parts of polypropylene, 2 parts of auxiliary agent, 3 parts of pelletted pitch, 5 parts of talcum powder, 1.5 parts of anti-hydrolysis agent.
Including the following raw material preferably, according to the number of parts by weight: 48 parts of PBT resin, 8 parts of PMMA resin, heat stabilizer
1.5 parts, 6 parts of toughener, 13 parts of polypropylene, 2.5 parts of auxiliary agent, 4 parts of pelletted pitch, 6 parts of talcum powder, 1.2 parts of anti-hydrolysis agent.
The utility model has the advantages that compared with prior art, composite material of the invention is by each component of proper content range molten
Melt in extrusion process and interacts, so that PBT composite of the present invention has excellent high temperature resistant hydrolysis property, so that with
The PBT composite is that the product of raw material can be used in hygrothermal environment for a long time.
