Technical field
The present invention relates to a kind of recovery and molding process of polypropylene composite waste material, specifically be used for the recycling of automotive upholstery scrap stock.
Background technology
Polypropylene (PP) galss fiber reinforced resin based composites also has than the more corrosion resistant characteristics of metal except in light weight, energy-conservation, safe, comfortable advantage, especially the high gasoline of methanol content is had better tolerance.In addition, it is big that the galss fiber reinforced resin based composites also has a design flexibility, and handling ease can reach one-step moulding to complicated shape, realizes automatization easily, thereby can reduce production costs.Therefore, grow with each passing day at the consumption of automotive field galss fiber reinforced resin based composites, its consumption proportion in automobile has often become to weigh an important symbol of automotive industry level.
Be accompanied by improving constantly of China's rapid economy development and sustainable growth and living standards of the people, the domestic automobile consumption increases sharply year by year.Thereby will break out the surge of scrap-car after the several years, if perplexing people's the whole world " white pollution " problem for a long time, present stage also can not get good solution, the physical and mental health that will directly have influence on people's quality of life even threaten people always.
The polypropylene-base glass fibre reinforced composion is a kind of typical thermoplastic polymer based matrix material, compares with the thermoset polymer matrix composites of a large amount of uses in the past, and returnability is its important characteristic.
At present, the main method of waste and old polypropylene base glass fibre reinforced composite recovery has burning method and pyrolysis method.China also is being in the starting stage aspect the recovery of galss fiber reinforced resin based composites, and what the overwhelming majority was used is burning method.But burning method had not both had economic benefit can be sayed, the more important thing is and can cause secondary pollution, so it is not to be a kind of long-term feasible recovery method.Therefore, the recycling of waste and old polypropylene base glass fibre reinforced composite, for turn waste into wealth, environment protection is very necessary.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point; thereby provide a kind of polypropylene compound waste leftover material convenient sources; production technique is simple; rapid shaping is difficult for causing secondary pollution, helps protecting environment; can realize the utilization again of waste material; turn waste into wealth, and can reduce production costs, the recovery and molding process of a kind of polypropylene composite waste material that helps increasing economic efficiency.
Main solution of the present invention is achieved in that
The present invention with polypropylene composite waste material after crushed, add virgin pp, silane coupling agent and lubricating auxiliary agent uniform mixing and make compound, compound is through heating, Heating temperature: 200-220 ℃, be incubated to compound and enter molten state, in mould, put into glasscloth, again the molten state compound is added mold pressing in the mould, dwell time is: 1-3min obtains the goods finished product behind the cooling demoulding.
Getting polypropylene composite waste material among the present invention is: 40-50 weight %, polypropylene are: 30-41 weight %, silane coupling agent are: 10-12 weight %, lubricating auxiliary agent: 5-8 weight %, glasscloth: 5-6 weight %.
Soaking time is among the present invention: 3-10min; Moving the material time is: 50-70s; Cooling temperature is below 70 ℃; The thermoplastic material virgin pp adopts particle usually among the present invention; Glasscloth can be according to the requirement of product strength, uses one deck or two layers up and down.
Among the present invention in the mould molding pressure be: 1-2MPa;
Polypropylene composite waste material is pulverized and is among the present invention: the particle of 1～5mm or sheet.
Compared with the prior art the present invention has the following advantages:
The compound waste leftover material convenient sources of the present invention, production technique is simple, is difficult for causing secondary pollution, helps protecting environment, can realize the utilization again of waste material, turns waste into wealth, and can reduce production costs, and helps increasing economic efficiency; Product properties through reclaiming moulding is stable, in light weight, corrosion-resistant, design flexibility big, handling ease, and aspect automotive trim, it is widely used in making component such as collision bumper, back luggage carrier, seat, splash pan, wheel cover.
