Embodiment Construction

[0009] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0010] The invention describes a modified expandable polystyrene rubber, which is composed of expandable polystyrene plastics, flame retardants, toughening agents, fillers, impact modifiers and dispersants. The combustion agent is boric acid, the toughening agent is liquid silicone rubber, the filler is talcum powder, the impact modifier is chlorinated polyethylene, and the dispersant is ethylene bisstearamide. The parts by weight of the components of the modified expandable polystyrene rubber are respectively: the expandable polystyrene plastic accounts for 70-75 parts, the boric acid accounts for 6-10 parts, and the liquid silicone rubber accounts for 18-22 parts, the talcum powder accounts fo...

Abstract

The invention discloses modified expandable polystyrene rubber. The modified expandable polystyrene rubber is prepared from expandable polystyrene plastic, fire retardant, flexibilizer, filler, anti-impact modifier and dispersant, the fire retardant is boric acid, the flexibilizer is liquid silicon rubber, the filler is talcum powder, the anti-impact modifier is chlorinated polyethylene, and the dispersant is ethylene distearamide. The modified expandable polystyrene rubber is prepared from, by weight, 70-75 parts of expandable polystyrene plastic, 6-10 parts of boric acid, 18-22 parts of liquid silicon rubber, 29-33 parts of talcum powder, 14-18 parts of chlorinated polyethylene and 9-13 parts of ethylene distearamide. The modified expandable polystyrene rubber has the advantages of being high in fire retardance and strength, high in impact strength and hardness, low in cost and good in quality.

Description

technical field [0001] The invention relates to the field of rubber and plastics, in particular to a modified expandable polystyrene rubber. Background technique [0002] Styrofoam board is one of three common interior wall insulation materials. Also known as foam board and EPS board, it is a white object formed by heating expandable polystyrene beads containing volatile liquid foaming agent in a mold after heating and pre-expanding. According to the structural characteristics of micro-closed cells, it is mainly used for building walls, roof insulation, composite board insulation, etc. Divided into expansive EPS board (benzene board) and continuous extruded XPS board (extruded plastic board). [0003] However, there are great deficiencies in polystyrene foam boards, such as poor flame retardancy, low strength, and unstable quality, resulting in poor use effects. Contents of the invention [0004] The purpose of the present invention is to provide a modified expandable p...
