Description
Technical field
The present invention relates to a kind of plastic filler parent granule and preparation method thereof.
Background technology
Along with the develop rapidly of plastics industry, plastics are widely used.Modifying plastics also becomes a Hot subject both domestic and external.Adding packing material in plastics is very commonly use in the modifying plastics method a kind of,, by adding some auxiliary agents, not only can reduce the production cost of plastics, improves the utilization ratio of resin, can enlarge the range of application of resin simultaneously.
The traditional method of modifying plastics be with packing material and auxiliary agent etc. directly mixing add again in matrix resin and carry out again forming process, but that this method is difficult to filler, auxiliary agent and mixed with resin is even.The improvement that the filling plastic modified master batch continues to the traditional method of modifying plastics produces, it can be when guaranteeing good processing characteristics can more convenient more interpolation filler, reduce costs to reach, improve the purposes such as processing characteristics.
At present, the packing material that the plastic working master batch is continued to use all the time is essentially calcium carbonate, magnesiumcarbonate, talcum powder, potter's clay, kaolin, mica, carbon black etc., these packing materials can not meet the requirement of plastics to product performance and improvement effect, and oil-absorption(number) is larger, the plastics light absorptive that makes is large, thereby causes product surface the cloudy surface effect to occur.In addition,, if loading level increases, tend to make the goods physical and mechanical properties of filling to reduce, affect the quality of plastics, goods are easily aging.
Summary of the invention
Cause greatly the plastics physical and mechanical properties poor for solving existing plastic filler parent granule loading level, quality of products, surface gloss is poor, easily aging problem, the object of the invention is to prepare a kind of low cost, environmental protection, can keep plastic filler parent granule of plastics physicals and preparation method thereof.
The technical solution adopted in the present invention is: a kind of plastic filler parent granule, it contains vector resin, terephthaldehyde's acid metal salt, silane coupling agent and lubricant.
As preferably, described vector resin is selected from newborn plastics or reprocessed plastic(s).
