Abstract
The invention discloses high-temperature-resistant and acid-and-base-resistant plastic. The plastic comprises the following active ingredients in parts by weight: 32-40 parts of acrylonitrile, 25-35 parts of butadiene, 32-40 parts of styrene, 15-20 parts of epoxy resin, 18-28 parts of polytetrafluoroethylene, and 23-30 parts of talcum powder. The plastic is subjected to flame retardance and acid and base resistance experiments. The flame retardance of the plastic is tested by adopting UL94 standard, the result shows that the flame retardance effect of the plastic can achieve V-0 grade, and the plastic has an excellent effect. In addition, the plastic has no any abnormal phenomenon after being respectively soaked in 2mol/L sodium hydroxide solution and 2mol/L phosphoric acid solution for 18-20 days, thus having excellent acid and base resistance property.
Description
Technical field
The present invention relates to a kind of plastic cement of high temperature-resistant acid-resistant alkali, belong to plastic material field.
Background technology
Plasthetics can be applied in a lot of aspects, as motorcycle pedal, electronic product, runway etc.In the middle of plastic cement application, people more and more pay close attention to the performance of plastic cement.But, most of plastics are owing to itself adding softening agent etc. to make it have inflammableness, temperature is slightly high is melting, therefore greatly reduce the security that plastics use, along with plastics are in the widespread use of the aspects such as building, furniture, traffic, Aeronautics and Astronautics, electrical equipment, the high thermal resistance that improves plastics has become very urgent problem.In addition, most of plastic cement acid resistances are all very poor, can not adapt to some particular requirement.
Therefore a kind of plastic cement of high temperature-resistant acid-resistant alkali is to have very much market outlook.
Summary of the invention
The technical problem solving: conventional plastic cement is high temperature resistant and the poor problem of acid and alkali-resistance effect.
Technical scheme: the present invention is a kind of plastic cement of high temperature-resistant acid-resistant alkali, is made up of according to weight ratio following composition: 23～30 parts of 32～40 parts of vinyl cyanide, 25～35 parts of divinyl, 32～40 parts of vinylbenzene, 15～20 parts of epoxy resin, 18～28 parts of tetrafluoroethylene and talcum powder.Wherein, vinyl cyanide and cinnamic weight ratio are 1:1.
At 120 DEG C, various compositions are dropped into reaction vessel allotment, stir, keep 6h, be placed in mould of die casting machine die cast and can obtain the plastic cement with high temperature-resistant acid-resistant alkali.
Beneficial effect: plastic cement of the present invention has been carried out to the experiment of flame retardant resistance and resistance to acids and bases.Adopt UL94 standard to test the flame retardant resistance of plastic cement, result shows that plastic cement flame retardant effect of the present invention can reach V-0 rank, has good flame retardant effect.Plastic cement of the present invention soaks 18～20 days respectively in the sodium hydroxide solution of 2mol/L and the phosphoric acid solution of 2mol/L in addition, produces without any unusual phenomenon, has good resistance to acids and bases.
