Abstract
The invention discloses a modified heat-resistant plastic which is prepared from a polyvinyl chloride resin, an acrylic resin, aluminum powder, modified glass fibers, calcium stearate, a dispersing agent, a heat stabilizer and a plasticizer. In order to overcome the defects in the prior art, a special method is adopted to modify the glass fibers, thereby enhancing the mechanical properties of the polyvinyl chloride plastic, improving the anti-friction and wear-resistant properties, and enhancing the weather resistance; the aluminum powder and calcium stearate subjected to high-temperature treatment are adopted to further enhance the heat resistance; and the production technique is simple and low in cost, and the prepared plastic has excellent heat stability.
Description
Technical field
The present invention relates to plastic production field, particularly relate to a kind of modified heat resistant plastics.
Background technology
General igelite on market, the degree of branching is less, relative density about 1.4, second-order transition temperature 77 ~ 90 DEG C, about 170 DEG C start to decompose, to the poor stability of light and heat, more than 100 DEG C or through long-time exposure in sunshine, will decompose and produce hydrogenchloride, and autocatalytically is decomposed further, cause variable color, physical and mechanical properties also declines rapidly.
Summary of the invention
The object of this invention is to provide a kind of modified heat resistant plastics, be achieved through the following technical solutions:
A kind of modified heat resistant plastics, described modified heat resistant plastics are made up of following composition by weight: polyvinyl chloride (PVC) RESINS 45 parts, acrylic resin 32 parts, aluminium powder 10 parts, modified glass-fiber 6 parts, calcium stearate 1 part, dispersion agent 3 parts, thermo-stabilizer 2 parts, 1 part, softening agent.
Further, described aluminium powder is calcined through 200 DEG C of aerobics.
Further, described dispersion agent is Sodium hexametaphosphate 99.
Further, described thermo-stabilizer is dibasic lead phosphite.
Further, described softening agent is citrate.
Further, the making method of described modified glass-fiber is, after glass fibre being immersed at 65-70 DEG C silane coupling agent 2-3 hour of 0.5-1% concentration, adding Xylo-Mucine, is heated to 85-90 DEG C, continue 1-1.5 hour, filter, dry.
The invention has the beneficial effects as follows: the present invention is directed to prior art above shortcomings, (1) the present invention carries out modification by adopting special methods to glass fibre, the mechanical property of igelite can not only be promoted, strengthen its properties of antifriction and wear resistance, its weather resistance can also be improved; (2) the present invention is by adopting aluminium powder and the calcium stearate of pyroprocessing, promotes its thermotolerance further; (3) production technique of the present invention is simple, and cost is low, and the plastics of making have excellent thermostability.
