Abstract
The invention discloses a formula of a modified polypropylene composite material with low shrinking percentage. The formula comprises the components in parts by weight as follows: 50-70 parts of polypropylene, 10-15 parts of polyethylene, 10-20 parts of POE (Polyolefin Elastomer), 20-30 parts of opal, 1-3 parts of silane coupling agent, 2-5 parts of talcum powder and 1-3 parts of assistant. According to the invention, opal is added into the formula to modify the surface of the opal through the silane coupling agent and the talcum powder, so that inorganic filler in the composite material not only has the weight increasing effect, but also enables the modified polypropylene composite material to have lower shrinking percentage and low price and cost. Other performances of the composite material are not affected, and the appearance quality is not affected, so that the material is very suitable for application.
Description
Technical field
The present invention relates to a kind of formula and production method thereof of modified polypropylene composite material, especially relate to a kind of formula and production method thereof with modified polypropylene composite material of lower shrinking percentage, belong to chemical technology field.
Background technology
For a long time, the aspects such as polypropylene composite material is little with its density, rigidity, insulativity, erosion resistance all have good performance, and are widely used.And polyacrylic shrinking percentage is very important performance perameter of modified polypropene.Improving at present the effective means of polypropylene shrinking percentage mainly contains following several:
1, add mineral powder: this kind method shrinking percentage improvement effect is not clearly;
2, add glass fibre: shrinking percentage can effectively be reduced, still, can destroy polyacrylic toughness, and visual appearance descends obviously;
3, adopt the method preparation of blend rubber: this kind method can effectively reduce shrinking percentage, but expensive, can greatly increase production cost, is unfavorable for market competition.
Summary of the invention
In order to overcome the deficiencies in the prior art, the object of the present invention is to provide and a kind ofly can effectively reduce shrinking percentage, and can guarantee formula and the production method thereof of the low-shrinkage modified polypropylene composite material of other property indices of modified polypropylene composite material.
The present invention is achieved through the following technical solutions:
