Abstract
The invention provides a heat-resistant anti-aging automobile bumper which is characterized by including the following raw materials, by weight, 50-60 parts of polypropylene, 12-15 parts of oxidized polyethylene, 5-7 parts of nano silicon dioxide, 2-3 parts of an activating and toughening agent, 1-3 parts of an anti-oxygen agent, 2-4 parts of vinyltrimethoxysilane, 2-3 parts of maleic anhydride, 0.6-0.8 parts of salicylic-4-tert-butyl-phenyl ester, 2-3 parts of copper powder, 2-3 parts of an anti-aging agent MB, 0.8-1.2 parts of zinc oxide, 3-5 parts of a reinforcing filler and 2-4 parts of white oil. The polypropylene is modified by the vinyltrimethoxysilane and the nano silicon dioxide, and by means of the activating and toughening agent, the composite material is improved in toughness and anti-impact performance. The anti-oxygen agent provides excellent process stability for the propylene during the process. The reinforcing filler and other mineral components are added so that the product has high strength and toughness and is good in heat resistance and mechanical performance.
Description
Technical field
The invention belongs to bumper technical field, be specifically related to a kind of heat-resistant aged automobile bumper.
Background technology
Polypropylene (PP) is one of widely used thermoplasticity general-purpose plastics, production cost is low, and output is large, lightweight, cost performance is high, has good physicochemical properties, chemical-resistant resistance, thereby be widely used in the fields such as automobile, household electrical appliances, furniture, chemical industry, packaging. But it is non-polar material, be chemical inertness, with other polar materials, as poor in nylon (PA), polybutylene terephthalate (PBT), Merlon (PC) and inorganic filler, the compatibility of fortifying fibre, compatibility, limit further popularization and application.
Bumper is that a kind of surface area is large, complex-shaped thin-walled large-sized structural component, and it not only requires to have excellent high and low temperature impact flexibility, rigidity, resistance to ag(e)ing, heat resistance, cold resistance, also will have the performances such as oil resistant, lubricating oil, paint. Wherein the most important thing is to have higher impact flexibility and good processing flowability. Polypropylene (PP) is with advantages such as its low-density, easy-formation processing, recoverables, and the application on automobile constantly increases, and is particularly applied to prepare bumper, is consumption maximum in automotive plastic, plastics variety with the fastest developing speed. But the black brittleness of PP is poor, molding shrinkage is large, impact resistance is poor, therefore, during for bumper, need to, to its modification, promote the combination property of PP, make it meet automobile bumper material requirement.
Summary of the invention
Object of the present invention is exactly to provide a kind of heat-resistant aged automobile bumper in order to overcome the defect that above-mentioned prior art exists, and has improved toughness and the resistance to impact of composite, and the high and good toughness of intensity, has good heat resistance and mechanical property.
The technical scheme that the present invention takes is:
A kind of heat-resistant aged automobile bumper, is characterized in that, the each component of raw material is composed as follows according to weight portion:
Polypropylene 50-60 part, oxidic polyethylene 12-15 part, nano silicon 5-7 part, activation flexibilizer 2-3 part, antioxidant 1-3 part, vinyltrimethoxy silane 2-4 part, maleic anhydride 2-3 part, salicylic acid-4-tert-butyl group phenyl ester 0.6-0.8 part, copper powder 2-3 part, antioxidant MB 2-3 part, zinc oxide 0.8-1.2 part, reinforcer 3-5 part, white oil 2-4 part.
The particle diameter of described nano silicon is 60-80nm.
Described activation flexibilizer is the mixture that flexibilizer POE and flexibilizer EPDM form according to weight ratio 2:1.
Described antioxidant is that anti-oxidant DLTP and irgasfos 168 are the mixture of 1.2:1 composition according to mass ratio.
Described reinforcer is the mixture that glass fibre and talcum powder form according to weight ratio 3:2.
Beneficial effect of the present invention is:
The present invention carries out modification with vinyltrimethoxy silane and nano silicon to polypropylene, by adding activation flexibilizer, toughness and the resistance to impact of composite are improved, antioxidant makes polypropylene in process, possess good processing stability, adding of the mineral compositions such as reinforcer, make the high and good toughness of product strength, there is good heat resistance and mechanical property.
