Description
Technical field
The invention belongs to polymeric material field, be specifically related to a kind of wear-resisting enhanced polypropylene composite and application.
Background technology
Polypropylene (PP) is a kind of important plastics, is widely used in the field such as automotive upholstery, household electrical appliances, has easily one-tenth
Type, good toughness, intensity good, the series of advantages such as quality is light, corrosion-resistant, good hand touch and low cost high, heat insulation.But, as heat
There is the inferior positions such as wearability is not enough in the polypropylene of plastic material, when using it as the inside gadget of automobile or exterior part, often
Chang Yinwei wearability is not enough and causes the abrasion of part, thus is necessary to improve further the wearability of polypropylene material.
Patent documentation CN104214249A discloses a kind of ceramic brake, and it contains ceramic fibre, polypropylene fibre etc.
Various ingredients, composition is complicated and technology difficulty is big, is not suitable for commercial production." ceramic powders kind is to polyurethane for periodical literature
The impact of composite Erosive Properties " in describe different ceramic powders compound polyurethane material anti-wear performance changed
Kind, but have no its linguistic term for PP composite material anti-wear performance.
Additionally, the volatile organic matter that plastics are brought (Volatile organic compounds, VOC) also becomes
Main harmful gas composition, creates serious threat to the health of people.Grind currently, with respect to low VOC polypropylene material
The report studied carefully is more, and they use chemical reaction, physical absorption and melt devolatilization technology to improve original polypropylene material mostly
In material, VOC's distributes problem.VOC reduction and the wearability of paying close attention to PP composite material in prior art change the most simultaneously
Kind, the application proposes solution for above-mentioned the deficiencies in the prior art.
Summary of the invention
Goal of the invention: in order to overcome the defect that low VOC PP composite material exists present in prior art, the present invention
Purpose be to provide a kind of wear-resisting enhanced polypropylene composite, reduce its VOC toxicity improving while wearability, thus
This PP composite material is enable to be preferably applied on the exterior part of automotive upholstery or automobile, such as vehicle steering
Deng.
Technical scheme: for achieving the above object, the present invention by the following technical solutions:

As preferably, described VOC inhibitor includes nano photo-catalytic, attapulgite, meerschaum and kieselguhr.This VOC presses down
Preparation utilizes attapulgite, meerschaum and diatomaceous loose structure to adsorb organic volatilization gas, utilizes nano photo-catalytic to be catalyzed
Degraded harmful gas makes its rapid oxidation be decomposed into stable and harmless material, to reduce the purpose of VOC content in car.
As preferably, the particle diameter of described hollow glass micropearl is 1-3mm, and the surface-coated of described hollow glass micropearl is compatible
Agent.The particle diameter of this hollow glass micropearl and it is worn and torn in the course of processing at its surface-coated compatilizer with fiberglass reinforced PP
Less, and it can effectively reduce density as filler.
As preferably, described compatilizer is selected from anhydride and polyacrylic graft polymers, and wherein preferably maleic anhydride is grafted
Polypropylene PP-g-MAH, the percent grafting of described PP-g-MAH is 2.5-3.0wt%, melt index is 120-200g/10min.
As preferably, described glass fibre is long glass fibres, a length of the 15 of described long glass fibres～25mm.
As preferably, described ceramic powders is selected from TiC, WC, Si3N4, TiN ceramic powders, the particle diameter of ceramic powders is 10-
100μm。
Invention further provides the application in automotive upholstery of the above-mentioned wear-resisting enhanced polypropylene composite,
Especially as vehicle steering materials'use.
Beneficial effect: compared with prior art, the invention have the advantages that
1, in the PP composite material of the present invention, VOC inhibitor can adsorb organic volatilization gas, solves and is using
The health problem that human body may be produced during PP composite material；
2, the present invention with the addition of glass fibre, improves toughness and the intensity of material, is with a wide range of applications；
3, the present invention with the addition of ceramic powders composition in the composite, drastically increases the wearability of material, makes material
Material still can keep outward appearance constant in long friction environment.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is further explained.
