Abstract
The invention discloses a flame-treatment-free polypropylene composite for an instrument board. The polypropylene composite is characterized by comprising the following raw materials in percentage by weight: 52-79.4% of polypropylene, 15-25% of talcum powder, 5-20% of composite elastomer, 0.2-1% of a main antioxidant, 0.2-1% of an auxiliary antioxidant and 0.2-1% of a processing aid. The polypropylene composite has the benefits as follows: on the basis of a polypropylene instrument board technology, the manner that the nonpolar elastomer and the polar elastomer are combined is adopted creatively, so that excellent performance of the instrument board material is ensured, in addition, the surface tension of the instrument board material is improved enough to reach a slush-molding foaming level, and slush-molding foaming can be achieved without flame treatment. Compared the prior art, the polypropylene composite has the advantage that the production cost of the instrument board is greatly reduced.
Description
Technical field
The present invention relates to one and exempt from flame treating dashboard polypropylene composite and preparation method thereof, belong to macromolecular material and forming process field thereof.
Background technology
Along with the fast development of petrochemical industry, polypropylene material substitutes the engineering plastics such as traditional ABS, PC/ABS, PBT and PA gradually with the advantage of its high performance-price ratio, is widely used in automotive interior/exterior material.
Automobile instrument panel material also becomes the higher polypropylene material of cost performance from traditional PC/ABS, ABS material, the dashboard material of middle and high end car is for giving its good sense of touch, mode slush moulding one deck polyurethane foaming layer in the middle of dashboard body and skin of usual employing slush moulding foaming, and urethane is polar resin, polypropylene is then non-polar resin, the two polarity spectrum is too large, and its capillary difference is not enough to make polyurethane foaming layer in polypropylene body surface good bonding.Therefore need to carry out flame treating to polypropylene body in traditional slush moulding dashboard production process, make Surface Creation carbonyl, hydroxyl isopolarity group, these polar groups improve polyacrylic surface tension on the one hand, on the other hand, hydroxyl can form chemical bond with the isocyanate reaction in polyurethane component, this further increases the bonding force of polypropylene and polyurethane foaming layer.Flame treating operation is loaded down with trivial details, produces and adds a lot of cost, be therefore badly in need of a kind of dashboard polypropylene material without the need to flame treating of exploitation to dashboard.
For solving the problem, the present invention is on the basis of conventional instrument plate body polypropylene material, adopt the method for adding polar elastomers to improve the surface tension of polypropylene material, improve the bonding force of polypropylene and polyurethane foaming layer, and then reach slush moulding adhesiveproperties.
Summary of the invention
The object of this invention is to provide one and exempt from flame treating dashboard polypropylene composite and preparation method thereof, to overcome the defect that prior art exists, meet the needs of automotive interior/exterior material development.
In order to achieve the above object, the present invention is achieved through the following technical solutions.
One exempts from flame treating dashboard polypropylene composite, is made up of the raw material of following percent by weight:
Preferably, described polypropylene selects melt flow rate (MFR) to be one or more mixtures in the homo-polypropylene of 1 ~ 100g/10min, atactic copolymerized polypropene.
Preferably, described talcum powder is the above talcum powder of 2000 order.
Preferably, described composite elastic body is that elastomerics A and elastomerics B combine, its elastomer A is non-polar elastomer, is one or more the mixing in ethylene-propylene copolymer, ethylene-octene copolymer, ethylene-butene copolymer and ethylene-propylene-octene terpolymer; Elastomerics B is polar elastomers, is the one or more kinds of mixing in ethylene/vinyl acetate copolymer, ethene/acrylic ester multipolymer, ethene/acrylic ester/maleic anhydride and ethene/acrylic ester/glycidyl methacrylate copolymer.
Preferably, described primary antioxidant is the phenols of functionality 1-4 and one or more mixtures of amine antioxidants kind.
Preferably, described auxiliary antioxidant is one or more the mixture in phosphorous acid esters and monothioester.
Preferably, described processing aid is one in low molecule ester class, stearic acid complex ester class and amides or two or more combination.
The above-mentioned preparation method exempting from flame treating dashboard polypropylene composite, concrete steps are as follows:
1) each raw material is taken by proportioning;
2) by step 1) individual raw material to drop into length-to-diameter ratio be melting mixing dispersion in the twin screw extruder of 40:1, extruding pelletization, finally obtains product.
Compared with prior art, the present invention has following beneficial effect;
In existing polypropylene dashboard material, usual employing acrylic resin, talcum powder, based elastomers and oxidation inhibitor and processing aid composition, the feature of this formula combination is that polarity is low, cause final material to be used as slush moulding dashboard body, flame treating just must can reach rational surface tension.
The mode of the present invention creationary employing non-polar elastomer and polar elastomers combination on the basis of polypropylene dashboard technology, not only ensure that the performance of dashboard material excellence, and its surface tension is brought up to be enough to the level of carrying out slush moulding foaming, can slush moulding foaming without the need to increasing flame treating operation.
Therefore, compared to existing technology, material of the present invention greatly reduces dashboard production cost.
