Abstract
The invention discloses heat-resistant modified composite plastics which comprise polypropylene, thermoplastic styrene butadiene rubber, mixture of silica powder and aluminum powder, phenolic resin, mixture of bentonite and kaolin, sodium acrylate, aluminum nitride, dispersing agent, plasticizer and heat stabilizer. The heat-resistant modified composite plastics are stable in quality, good in mechanical, physical and chemical properties, adaptability and economy. By adding the silica powder and the aluminum powder which have undergone mixed treatment, the heat resistance of the composite plastics is improved greatly, and the structure of the heat-resistant modified composite plastics is improved; by mixed pretreatment between the phenolic resin and aluminum nitride, the plastic components can be more uniform; and by adding the bentonite and the kaolin which have undergone mixed treatment, the weather resistance of the composite plastics is improved greatly, and the secondary processing performance of the heat-resistant modified composite plastics is enhanced. In processing preparation, first polypropylene and sodium acrylate are mixed and added into a twin-screw extruder, the integration of polypropylene and other components can be improved, and the structural quality and service lives of the composite plastics are improved.
Description
Technical field
The present invention relates to plastic production field, particularly relate to a kind of heat resistance modified composite plastic.
Background technology
The erosion resistance of polypropylene (PP), rigidity and transparency are better, are widely used in making packaging vessel at present.But polypropene impact-resistant is poor, become fragile during low temperature, more aging, and vast producer dropping into reduce starting material, reducing production cost, make that the packaging vessel weight made is lighter, container wall thickness is thinner as much as possible, therefore, existing is former with polypropylene
The packaging vessel feel that material is made is very soft, insufficient strength is high, yielding when taking, cracked, be difficult to splendid attire liquid state or semi liquid state packing material, when the liquid state that particularly splendid attire temperature is higher or semi liquid state material, the liquid state that temperature is higher or semi liquid state material easily overflow and damage human body.Therefore, need to carry out composite modified to it, solve these problems.
Summary of the invention
The object of this invention is to provide a kind of heat resistance modified composite plastic, be achieved through the following technical solutions:
A kind of heat resistance modified composite plastic, is made up of following composition: polypropylene 95 parts, thermoplastic styrene butadiene rubber 20 parts, silica flour and al powder mixt 11 parts, 28 parts, resol, wilkinite and kaolin mixture 5 parts, sodium acrylate 5 parts, aluminium nitride 8 parts, dispersion agent 1 part, 0.5 part, softening agent, thermo-stabilizer 0.2 part by weight.
The above-mentioned dispersion agent described in Raw, softening agent, thermo-stabilizer do not comprise the content of the component comprised in raw material, and such as, sodium acrylate can use as dispersion agent, but above-mentioned describe in dispersion agent do not comprise sodium acrylate.
Further, described silica flour mixes with the phosphoric acid solution of 4.5% concentration after 200 DEG C of aerobics are calcined with al powder mixt again, constant temperature process 1-1.5 hour at 80-95 DEG C, filters, dry; Described silica flour mixes in 3:1 ratio with aluminium powder.
Further, described dispersion agent is Sodium hexametaphosphate 99, and described softening agent is citrate, and described thermo-stabilizer is dibasic lead phosphite.
Further, described wilkinite and kaolin mixture are through process modification process: after adopting the sodium hydroxide solution of 5mol/L concentration to soak 1 hour, filter, adopt clear water to be washed till neutrality, then add the vinylformic acid of wilkinite and kaolin mixture 1% weight, after stirring, carry out heating grinding after 30 minutes, be cooled to room temperature, filter, dry, pulverize to 100-150 order; Described wilkinite mixes in 3:2 ratio with kaolin.
Further, described resol and aluminium nitride are through pre-treatment: resol and aluminium nitride are mixed and heated to resol and melt completely, continue after 20 minutes, are quickly cooled to greenhouse.
Further, when composite plastic is prepared in processing, first polypropylene is mixed with sodium acrylate and add in twin screw extruder after 30 minutes, then add other composition.
The invention has the beneficial effects as follows: (1) steady quality of the present invention, mechanical-physical chemical property are good, have good adaptability, economy.(2) the present invention is by adding the silica flour after blended process and aluminium powder, greatly improves the resistance toheat of composite plastic, improves its weave construction and forms; By to mixing pre-treatment between resol with aluminium nitride, plastic components can be made more even, and weave construction is more firm; By adding the wilkinite after blended process and kaolin, greatly improving the weathering resistance of composite plastic, improving its suitability for secondary processing; When processing preparation, first polypropylene being mixed with sodium acrylate and adding in twin screw extruder, the amalgamation of polypropylene and other composition can be improved, improve its structural quality and work-ing life.
