Abstract
The invention discloses high-strength foamed plastic which is composed of polycarbonate raw materials, light inhibitor, antioxidant and plasticizer. The high-strength foamed plastic further comprises fire retardant, foaming agents and filling agents. The filling agent is mixture of glass fibers and teflon fibers, the light inhibitor is diphenyl ketone type stabilizer, and the plasticizer is chlorinated paraffin. The high-strength foamed plastic comprises, by weight, 62-73 parts of polycarbonate raw materials, 2-5 parts of light inhibitor, 3-6 parts of antioxidant, 2-6 parts of plasticizer, 3-5 parts of fire retardant, 2-4 parts of foaming agents, 13-15 parts of glass fibers and 1-3 parts of teflon fibers. In this way, according to the high-strength foamed plastic, the foaming agents form a micro hole structure in the plastic and reduces the density of the plastic, the mixture of the glass fibers and the teflon fibers can improve the strength of the plastic, and plastic products are made light and firm.
Description
Technical field
The present invention relates to plastic formula design field, particularly relate to a kind of high strength expanded plastic.
Background technology
In order to reduce the weight of plastic prod, common way adds pore forming material in the feed, makes to form continuous or discontinuous microporous type structure in plastics, thus decrease the use of raw material, reduce raw materials for production cost and product substance.
Because pore forming material reacts in plastics-production process, microporous type structure decreases weight on the one hand, makes product become slim and graceful, on the other hand, also destroys original dense structure, reduce the structural strength of product, need to improve in intensity.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of high strength, lightweight expanded plastic.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of high strength expanded plastic, by polycarbonate raw material, light inhibitor, oxidation inhibitor and softening agent composition, also containing fire retardant in described high strength expanded plastic, whipping agent and weighting agent, described weighting agent is glass fibre and polytetrafluoroethylene fiber mixture, described light inhibitor is benzophenone stablizer, described softening agent clorafin, in described high strength expanded plastic, the parts by weight of each composition are: polycarbonate raw material 62 ~ 73 parts, light inhibitor 2 ~ 5 parts, 3 ~ 6 parts, oxidation inhibitor, 2 ~ 6 parts, softening agent, fire retardant 3 ~ 5 parts, whipping agent 2 ~ 4 parts, 13 ~ 15 parts, glass fibre and polytetrafluoroethylene fiber 1 ~ 3 part.
In a preferred embodiment of the present invention, described oxidation inhibitor is antioxidant 1010.
In a preferred embodiment of the present invention, in described high strength expanded plastic, the parts by weight of each composition are: polycarbonate raw material 65 parts, light inhibitor 3 parts, 4 parts, oxidation inhibitor, 3 parts, softening agent, fire retardant 3.5 parts, whipping agent 2.5 parts, 14 parts, glass fibre and polytetrafluoroethylene fiber 2 parts.
The invention has the beneficial effects as follows: a kind of high strength expanded plastic that the present invention points out, whipping agent forms microporous type structure in the plastic, reduce density, and glass fibre and polytetrafluoroethylene fiber mixture can improve the intensity of plastics, make plastic prod merrily and lightheartedly and firmly.
