XPS composite flame retardant

Abstract

The invention provides an XPS composite flame retardant. The flame retardant is prepared from the following raw materials in parts by weight: 3-6 parts of polyethylene wax, 50-80 parts of chlorinatedparaffin, 30-45 parts of hexabromocyclododecane, 1-2.5 parts of a stabilizer, 1-2 parts of titanium dioxide, 0.8-1.2 parts of antimonous oxide, 0.8-1.2 parts of calcium stearate, 0.8-1.1 parts of leadstearate and 2-4.8 parts of talcum powder. Compared with the traditional preparation process of thermal forming, wire-drawing, pelletizing and cooling, the preparation method has the advantages of short process flow, high preparation efficiency and the like. Meanwhile, due to the adoption of the cold extrusion process for preparation, the preparation process requirements of the flame retardant can be met by selecting a sulfur-free organic heat stabilizer, so that the composite flame retardant is green and environment-friendly, heating and cooling procedures in the preparation process can be omitted, energy consumption in the preparation process can be greatly reduced, and the working environment of workers is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical production, and in particular relates to an XPS composite flame retardant. Background technique [0002] With the development of China's synthetic material industry and the continuous expansion of application fields, flame retardants have broad market prospects in various fields such as chemical building materials, electronic appliances, transportation, aerospace, daily furniture, interior decoration, and basic necessities of life. In addition, fields such as coal fields, oil fields, and forest fire fighting have also promoted the rapid development of China's flame retardant and fire extinguishing agent production. China's flame retardant has developed into the second largest polymer material modification additive after plasticizers. The current production capacity is about 200,000 t / a, and the annual production volume is between 150,000 and 170,000 tons. The annual consumption About 200,000 ton...

Problems solved by technology

[0004] However, the existing flame retardants are mostly prepared by thermoforming, wire drawing, pelletizing, cooling and other methods during production and preparation. During the preparation process, the energy consumption is high, and the ball pressure on the stabilizer is high. complex and low production efficiency, so there is an urgent need for a composite flame retardant with high production efficiency, green environmental protection and excellent production environment to solve these problems
