Preparation device for rubber and plastic mixed high-flame-retardance thermal insulation materials

Abstract

The invention discloses a preparation device for rubber and plastic mixed high-flame-retardance thermal insulation materials. The preparation device comprises a crushing chamber, a heating chamber anda cooling chamber; a lifting motor is arranged at the top in the crushing chamber; a movable plate is arranged on one side of the lifting motor; saw teeth are welded at the bottom of the movable plate; multiple saw teeth are provided; a screen is arranged at the bottoms of the saw teeth; the heating chamber is arranged on one outer side of the crushing chamber; a conveying belt is arranged at thebottom of the screen; stepper motors are mounted on two sides of the conveying belt; the other end of the conveying belt is leaded into the heating chamber; a first motor is mounted on one side of the top of the heating chamber; a stirring shaft is mounted at the bottom of the first motor, and is introduced into the heating chamber; a spiral stirring paddle is mounted on the stirring shaft; and an electromagnetic heating block is arranged in the inner wall of the bottom of the heating chamber. The preparation device has the beneficial effects of simple preparation method and making up of thedefects of high operating cost and weak preparation effect in a traditional insulation material preparation device.

Description

technical field [0001] The invention relates to the technical field of preparation of a rubber-plastic blended high flame-retardant thermal insulation material, in particular to a preparation device for a rubber-plastic blended high flame-retardant thermal insulation material. Background technique [0002] There are three main types of polymer foam insulation materials, namely polyurethane, phenolic resin and urea-formaldehyde resin foam insulation materials. Among them, the first two types of thermal insulation materials, especially polyurethane foam materials, have excellent comprehensive performance indicators and have been widely used in industry and construction. However, due to the high cost of raw materials used, and the use of freon as a blowing agent in polyurethane resin will bring harm to the atmosphere (although freon is currently replaced by other materials), it limits its large-scale promotion in construction . Since the urea-formaldehyde resin foam insulatio...

AI Technical Summary

Problems solved by technology

In the prior art, the preparation effect of the rubber-plastic blended high flame-retardant thermal insulation material is poor, the mixing is insufficient, and the high-purity rubber-plastic blended high flame-retardant thermal insulation material cannot be obtained, and the operation cost of the preparation equipment is high. And the practicability is poor. If it is not used immediately after preparation and placed randomly, it will cause uneven foaming of the insulation material, which will bring unnecessary troubles.
