Formulation system suitable for wide hollow foam board

Abstract

The invention discloses a formulation system suitable for a wide hollow foam board. The formulation system is prepared from the following raw materials in parts by weight: 100-120 parts of a PVC resinpowder, 10-15 parts of nano titanium dioxide, 10-15 parts of nano calcium carbonate. 10-15 parts of nano silicon carbide, 10-15 parts of modified asbestos fibers, 10-12 parts of nano hydrated calciumsilicate, 10-12 parts of a foaming agent, 0.5-1.2 parts of a flame retardant, and 0.2-0.8 part of an antistatic agent. The system can increase the flame retardancy, antistatic property and self-cleaning property of the foamed board, and well overcomes the defects of poor flame retardancy and poor antistatic property of the foam board prepared by the formula for the wide hollow foam board in the prior art.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a formulation system suitable for wide-width hollow foam boards. Background technique [0002] The main chemical composition of foam board is polyvinyl chloride, so it is also called foamed polyvinyl chloride board. It is widely used in various fields such as industry, agriculture, transportation, construction, communication, medical care and health, such as industrial spare parts, tarpaulins, water pipes, plastic doors and windows, cable protective sleeves, medical products, etc. Although rigid PVC itself has excellent flame retardant properties, foaming will cause a decrease in the flame retardant properties of the material, and the smaller the density, the greater the drop, which poses a greater safety hazard during use after production; and the existing The antistatic performance of the foam board is poor. During actual use, it is easy to generate static electricit...
