Description
Technical field
The present invention relates to plastic production field, particularly relate to a kind of new 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 new modified composite plastic, be achieved through the following technical solutions:
A kind of new modified composite plastic, is made up of following composition: polypropylene 93 parts, thermoplastic styrene butadiene rubber 20 parts, silica flour and al powder mixt 10 parts, 26 parts, resol, wilkinite and kaolin mixture 6 parts, sodium acrylate 4 parts, aluminium nitride 6 parts, bauxitic clay 4 parts, 8 parts, bamboo powder, 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, bamboo powder is added in the hydrochloric acid of 3.5% concentration, after being heated to 60-70 DEG C, add the bright olefin(e) acid formicester of methyl, be heated to 85-90 DEG C, keep 30 minutes, then add bauxitic clay, be heated to 95-100 DEG C, keep after 45 minutes, be cooled to room temperature, filter, dry.
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.(3) by adding the bamboo powder of blended process and bauxitic clay, distortion and structure deteriorate that plastics cause under external stress can be reduced, and improve its erosion resistance.
