Abstract
The invention discloses novel modified plastics. The novel modified plastics comprise polyvinyl chloride resin, acrylic resin, aluminum powder, alkali lignin, calcium carbonate, dispersing agents, heat stabilizers and plasticizers. The novel modified plastics have the advantages that shortcomings in the prior art can be overcome by the aid of the novel modified plastics; the calcium carbonate is modified and treated by the aid of special methods and is matched with the alkali lignin, accordingly, the mechanical performance of the plastics and particularly, the tensile strength and the bending strength of the plastics, can be greatly improved, and the weather resistance of the plastics can be improved; the heat resistance of the plastics further can be enhanced owing to the aluminum powder which is treated at high temperatures; the novel modified plastics are simple in production process, low in cost and excellent in heat stability.
Description
Technical field
The present invention relates to plastic production field, particularly relate to a kind of new modified 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 new modified plastics, be achieved through the following technical solutions:
A kind of new modified plastics, described new modified plastics are made up of following composition by weight: polyvinyl chloride (PVC) RESINS 40 parts, acrylic resin 30 parts, aluminium powder 8 parts, alkali lignin 5 parts, 4 parts, calcium carbonate, 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, described calcium carbonate filters, by washed with de-ionized water after adopting 1-2% concentration methacrylic acid solution to soak 1 hour, and then gather butylacrylic acid solution soaking with 1-2%, be heated to 85-90 DEG C, keep after 1-2 hour, be cooled to room temperature, filter, by washed with de-ionized water, dry, pulverize to 50-100 order powder.
Further, described alkali lignin is extract gained in maize straw; Described alkali lignin adopts 1-3% cetyl trimethylammonium bromide solution after 55-60 DEG C of lower seal soaks 1-2 hour, filters, 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 calcium carbonate, the interpolation of alkali lignin is coordinated to use, great raising is had to the mechanical property of plastics, especially the tensile strength of plastics and flexural strength, and the weathering resistance of plastics can be improved; (2) the present invention is by adopting the aluminium powder of pyroprocessing, promotes the thermotolerance of plastics further; (3) production technique of the present invention is simple, and cost is low, and the plastics of making have excellent thermostability.
