Abstract
The invention discloses modified polypropylene plastic. The modified polypropylene plastic is prepared from polypropylene, acrylic resin, plant cellulose, dispersant, heat stabilizer, chitosan and plasticizer. The modified polypropylene plastic aims at overcoming the defects in the prior art. Plant cellulose is activated through the special physical and chemical properties of chitosan, so that plant cellulose and polypropylene are completely mixed, and the weather resistance of the polypropylene plastic is further improved; the production process is simple, cost is low, and the manufactured plastic has excellent heat stability; the modified plastic has better rigidity, impact resistance and flexibility.
Description
Technical field
The present invention relates to plastic production field, particularly relate to a kind of modified polypropylene plastic.
Background technology
The erosion resistance of polypropylene material, rigidity and transparency are better, are widely used in making packaging vessel at present.But, general polypropylene material shock resistance is poor, become fragile during low temperature, more aging, and, many producers dropping into reduce starting material, reducing production cost, reduce the use of polypropylene material as much as possible, therefore, the existing packaging vessel quality with polypropylene being starting material are made is soft, intensity is not low, can not meet the demand of many occasions.
Summary of the invention
The object of this invention is to provide a kind of modified polypropylene plastic, be achieved through the following technical solutions:
A kind of modified polypropylene plastic, described modified polypropylene plastic is made up of following composition by weight: polypropylene 45 parts, acrylic resin 32 parts, plant cellulose 16 parts, dispersion agent 4 parts, thermo-stabilizer 2 parts, chitosan 3 parts, 1 part, softening agent.
Further, described plant cellulose is obtained from maize straw.
Further, described dispersion agent is Sodium hexametaphosphate 99.
Further, described thermo-stabilizer is calcium iso-octoate.
Further, described softening agent is citrate.
A making method for modified polypropylene plastic, comprising:
1) take respectively by weight, polypropylene 45 parts, acrylic resin 32 parts, plant cellulose 16 parts, dispersion agent 4 parts, thermo-stabilizer 2 parts, chitosan 3 parts, 1 part, softening agent;
2) chitosan and plant cellulose are being put into 10% hydrochloric acid soln, soaking after 2 hours at 55-60 DEG C, with in sodium hydroxide solution and hydrochloric acid soln, after being heated to 85-90 DEG C, be cooled to room temperature, filter, dry;
3) polypropylene and acrylic resin are heated to molten state, with 2) Raw mixes, uniform stirring is after 30 minutes, and remix dispersion agent, thermo-stabilizer and softening agent, add in forcing machine, extruding plasticizing and uniformly plastics, the processing condition extruding process are: a district temperature 210-220 DEG C, two district temperature 220-240 DEG C, three district temperature 240-260 DEG C, four district temperature 260-270 DEG C, the residence time is 2 minutes.
The invention has the beneficial effects as follows: the present invention is directed to prior art above shortcomings, (1) the present invention carries out activation treatment by adopting the physicochemical property of chitosan uniqueness to vegetable fibre, vegetable fibre and polypropylene are merged more thorough, promote the weather resistance of acrylic plastering further; (2) production technique of the present invention is simple, and cost is low, and the plastics of making have excellent thermostability; (3) plastics of the present invention have better rigidity, shock resistance and suppleness.
