Abstract
A preparation technology of a novel environmentally friendly polyurethane foamed plastic relates to the technical field of polyurethane foamed plastics. The preparation technology comprises the following steps: mixing raw materials under high speed stirring, foaming, carrying out casting foaming, putting the obtained mixture in an established die, and carrying out single press molding at 60-100DEG C under 10-15Mpa, and the press molding time is determined by the practical die thickness according to 1-1.5mm/min. The preparation technology adopting a polyurethane foamed plastic as a base material, introducing foamed rubber in the foaming process and adopting recovered crushed EVA, PE and TPE as raw materials is in favor of realizing environmental protection and reducing the production cost, and the recovered raw materials are uniformly dispersed in the foamed plastic, so the foamed plastic has shock reduction and pressure reduction properties and strong elasticity; and lignocellulose is used as a filling reinforcing agent, so the elasticity, the compression set, the tension, tear strength and other physical and mechanical properties of the obtained product are improved.

Described polyether glycol is one or more in polyoxypropyleneglycol, tetrahydrofuran (THF)-propylene oxide copolymer glycols, special polyether polyvalent alcohol, and its actual model selected is determined according to the different demand of goods with ratio.
Described water is general pure water chain propagation agent, is simultaneously also that CO occurs
2bubble raw material sources.
Described catalyst action mechanism is for promoting that catalysis foaming and gel reaction carry out.
Originate as bubble after described whipping agent mechanism of action vaporization and remove reaction heat, avoid foam center Yin Gaowen and produce " burning ".
Described bamboo charcoal powder is bamboo charcoal raw material, evenly spreads in porous plastics base material after grinding to form ultrafine nanometer.
Described EVA and elastomeric material reclaimed materials are that the scrap stock reclaiming EVA and rubber pange carry out fragmentation, screening, add in porous plastics base material.
The present invention has following beneficial effect:
Proportion is light, has good intensity, elasticity and compressed shape variable simultaneously, and the obtained porous plastics possessing pooling feature, the field such as making, household living--room decoration building materials at special suitable for making high-grade sports shoes material shoe-pad and the middle end etc..The EVA added and elastomeric material reclaimed materials, under guarantee goods cost significantly reduction condition, keep superior elasticity and the physicals of goods, even more superior.Adding lignocellulose is again reinforcement system, and goods possess antibacterial, deodorizing, the characteristic such as ventilative.
