Abstract
The invention discloses modified plastic, which is prepared from polypropylene, acrylic resin, hu mulberry powder, a dispersing agent, a heat stabilizer, acetic anhydride, concentrated sulfuric acid and a plasticizer. Aiming at the defects of the prior art, the tensile strength and bending strength can be improved by adopting the modified hu mulberry powder; the modified plastic is simple in production process, low in cost and excellent in heat stability; and the modified plastic has good rigidity, impact resistance and flexibility.
Description
Technical field
The present invention relates to plastic production field, particularly relate to a kind of modified plastics.
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 plastics, be achieved through the following technical solutions:
A kind of modified plastics, described modified plastics is made up of following composition by weight: polypropylene 50 parts, acrylic resin 30 parts, 15 parts, Hu Sangmu powder, dispersion agent 3 parts, thermo-stabilizer 2 parts, diacetyl oxide 4 parts, the vitriol oil 3 parts, 2 parts, softening agent.
Further, described Hu Sangmu powder is made up of the Hu mulberry branch of life at least 3 years.
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 plastics, comprising:
1) take respectively by weight, polypropylene 50 parts, acrylic resin 30 parts, 15 parts, Hu Sangmu powder, dispersion agent 3 parts, thermo-stabilizer 2 parts, diacetyl oxide 4 parts, the vitriol oil 3 parts, 2 parts, softening agent;
2) at Hu Sangmu powder and diacetyl oxide, the vitriol oil, Homogeneous phase mixing to together, carries out after the first stage reacts 2 hours at 75-80 DEG C, and add the vitriol oil and be heated to 95-100 DEG C and carry out subordinate phase reaction, the reaction times is 2.5 hours;
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, tensile strength and the flexural strength of (1) the present invention by adopting modification Hu Sangmu powder to improve material; (2) production technique of the present invention is simple, and cost is low, and the plastics of making have excellent thermostability; (3) modified plastics of the present invention has better rigidity, shock resistance and suppleness.
