The polymer antistatic agent is adopted, and a special hydrophilic polymer, namely a polyamide polyether block copolymer, has good compatibility with resin; when the antistatic agent is added into plastic, a three-dimensional conduction network is formed with the plastic, and accumulated charges are dissipated through the conduction network, so that the antistatic effect is achieved.
Preferably, the heat-resistant agent is a resin heat-resistant modifier containing an N-phenylmaleimide structure, and the molecular formula is as follows. The engineering material is subjected to heat-resistant modification by adopting a resin heat-resistant modifier N-phenylmaleimide, and the cyclic structure of the resin heat-resistant modifier can increase the internal rotation resistance of a molecular chain, so that the Vicat softening point or the heat-resistant temperature of the engineering material is improved.

The two and three zones are set according to the melting temperature of the material, the melting point of the heat-resistant agent is higher, and the temperature of 260-270 ℃ is set to promote the melting and blending of the heat-resistant agent. The back section is a dispersing, distributing and conveying section, and the temperature is reduced by 10 ℃ to avoid yellowing and degradation caused by high temperature for a long time.
Preferably, the antistatic agent is a polyamide polyether block copolymer of the formula, wherein PA is a polyamide, including PA6, but not limited to PA 6; PE is a polyether, including polypropylene glycol, polytetrahydrofuran glycol or a copolymer of propylene glycol and tetrahydrofuran glycol. The polymer antistatic agent is adopted, and a special hydrophilic polymer, namely a polyamide polyether block copolymer, has good compatibility with resin; when the antistatic agent is added into plastic, a three-dimensional conduction network is formed with the plastic, and accumulated charges are dissipated through the conduction network, so that the antistatic effect is achieved.
Preferably, the heat-resistant agent is a resin heat-resistant modifier containing an N-phenylmaleimide structure, and the molecular formula is as follows. The engineering material is subjected to heat-resistant modification by adopting a resin heat-resistant modifier N-phenylmaleimide, and the cyclic structure of the resin heat-resistant modifier can increase the internal rotation resistance of a molecular chain, so that the Vicat softening point or the heat-resistant temperature of the engineering material is improved.

Preferably, the antioxidant is a composite antioxidant of tris [2, 4-di-tert-butylphenyl ] phosphite and n-octadecyl beta- (3, 5-di-tert-butyl-4-hydroxyphenyl) propionate. The molecular formula is as follows.
The lubricant is a modified stearate or a modified stearamide, preferably ethylene bis stearamide, of the formula. The stearic acid amide has different components and different functions, and the inherent fatty characteristics of stearic acid, including lubricity and water repellency, play a role in lubrication and improve the processability of materials.
Preferably, the ABS density is 1.03-1.07 g/cm3Melt flow rateThe rate is 15-25g/10min under the condition of 220 ℃ multiplied by 10 kg.
In conclusion, the invention has the following beneficial effects:
the high heat-resistant permanent antistatic material provided by the invention has both antistatic property and heat resistance by the synergistic use of the heat-resistant agent and the antistatic agent and the compounding of ABS.
The antistatic agent is a nylon elastomer of polyamide and polyether, and can be added into a base material only in a blending mode, and after being blended with a base, on one hand, because the movement capacity of molecular chains of the antistatic agent is strong, protons are easy to move among molecules, and static charges are conducted and leaked through the ionic conduction effect; on the other hand, the antistatic agent forms a conductive surface layer distributed in a rib or layer on the surface of a substrate and is distributed in a spherical or granular shape in the central portion to form a so-called "core-shell structure" which conducts and leaks static charge by serving as a conductive network path. The polyether can be combined with free ions through large-scale molecular movement of the polyether with low molecular mass and charge transfer along an ion network, the charge can move in a combined body mode to release static charge, and the nylon elastomer has high molecular mass and main polymer blending and has good permanent antistatic performance.
The heat-resistant agent is a resin heat-resistant modifier containing an N-phenylmaleimide structure. The N-phenylmaleimide structure has high decomposition temperature (752 ℃) and good stability, has good effect on heat-resistant modification of engineering materials, and has a cyclic structure which can increase the internal rotation resistance of a molecular chain, thereby improving the Vicat softening point or the heat-resistant temperature of the engineering materials, and obviously improving the heat-resistant effect and the antistatic property of the ABS materials.
