Abstract
The invention provides a high polymer material for enhancing the melt strength of PP plates. The high polymer material for enhancing the melt strength is prepared from the following raw materials in percentage by mass: 50-65% of thermosetting resin wastes, 25-40% of discarded chopped fiberglass shreds, 1-5% of polyolefin elastomer, and 2-6% of ethylene-vinyl acetate copolymer. According to the composition proportion of the high polymer material, the utilization ratio of wastes can reach over 97%; by using a characteristic of the thermosetting resin wastes that the thermosetting resin wastes can not be melted at high temperature and have certain elasticity, the formation of a bubble skeleton is facilitated; the high polymer material has good compatibility with a non-polar polymer material, so that the viscosity of melts is high, and the cost of plates is reduced by over 40%; and especially, the recycling of a thermosetting resin fertilizer is also not solved in good ways in domestic; according to the composition proportion, the regeneration recycling of resources is realized, so that the high polymer material has obviously significant economic, social and ecological benefits.
Description
Technical field
The invention belongs to plate product manufacture field, be specifically related to a kind of for strengthening the macromolecular material of PP sheet material melt strength.
Background technology
The micro-foaming of pp generates light weight board, in the starting material that generate sheet material, needing the raw material using is discarded PP, due to good fluidity after discarded PP melting, but melt strength is poor, be difficult to foaming and molding, the strength of materials after its moulding can not meet the requirement of general sheet material application, and the cost that former material uses is higher.
Summary of the invention
For above the deficiencies in the prior art, the invention provides a kind of for strengthening the macromolecular material of PP sheet material melt strength.
The present invention is achieved by the following technical solutions:
A kind of for strengthening the macromolecular material of PP sheet material melt strength, the macromolecular material that strengthens melt strength is made up of the raw material of following mass percent: thermosetting resin waste material 50-65%, discarded short chopping glass fibre 25-40%, polyolefin elastomer 1-5%, ethylene-vinyl acetate copolymer 2-6%.
Further, described thermosetting resin waste material is wherein one or both of thermoset epoxy compound polymkeric substance or heat-reactive phenolic resin.
Further, discarded short chopping glass fiber diameter is 10-30 μ m, and the length of discarded short chopping glass fibre is 2-5cm.
Further, the vinyl acetate content in ethylene-vinyl acetate copolymer is 5-15%.
Beneficial effect of the present invention is: this proportioning can make waste utilization accounting reach more than 97%, adopt thermosetting resin waste material can at high temperature not melt and have certain elastic feature, therefore be conducive to form bubble skeleton, simultaneously better with the consistency of non-polar polymeric material, make melt toughness high, board cost has just declined more than 40%, particularly the recycling of thermosetting resin fertilizer does not also have to solve with the approach of energy consumption at home, this proportioning has realized resource recovery recycle, and therefore economic society ecological benefits are particularly remarkable.
