Embodiment Construction

[0019] see figure 1 As shown, a foam board with high stability is made of the following raw materials in parts by weight: 100 parts of PVC resin, 4 parts of composite stabilizer, 4 parts of ACR-401D accelerator, 6 parts of foam regulator, foam 0.8 parts of PE wax, 30 parts of light calcium carbonate; the PVC resin adopts P-700 type PVC resin, its gelation speed is fast during processing, the processing temperature is relatively low, the product quality is stable, and the density is easy to control ; The foam regulator is a high molecular weight polymer with a multi-layer structure formed by acrylate monomers through multi-stage emulsion polymerization, and the foam regulator is JHB-42 or JHB-100.

[0020] The decomposition temperature of the foaming agent matches the dissolution temperature range of the PVC resin.

[0021] The PE wax is 0.6 parts of PE wax A-C6A and 0.4 parts of PE wax A-C316A respectively, and the total of the two groups is 1 part.

[0022] A method for pre...

Abstract

The invention discloses a high-stability foaming plate which is prepared from the following raw materials in parts by weight: 100 parts of PVC (polyvinyl chloride) resin, 4 parts of composite stabilizer, 4 parts of ACR-401D accelerator, 6 parts of foaming regulator, 0.8 part of foaming agent, 1 part of PE (polyethylene) wax and 30 parts of light calcium carbonate, wherein the PVC resin is a P-700 type PVC resin of which the gelation speed is high, the processing temperature is relatively low, the product quality is stable and the density is easy to control during processing; the foaming regulator is a high molecular weight polymer which is prepared from acrylate monomers through multi-stage emulsion polymerization and has a multilayer structure, and the foaming regulator is JHB-42 or JHB-100; and various assistants are added into the formula system to effectively lower the plastication temperature, promote the plastication effect, improve the plastication efficiency, enhance the melt intensity, reduce the melting pulsation, prevent the melt fracture and obviously improve the surface smoothness of the product. Thus, the product quality is ensured, and the product grade is improved; and meanwhile, the relationship between the formula cost and the comprehensive cost can be wholly mastered to achieve optimal economic benefits.

Description

technical field [0001] The invention belongs to building materials, and in particular relates to a foam board with high stability and a preparation method thereof. Background technique [0002] Due to its excellent performance, PVC foam materials are widely used in construction, building materials, decoration, home furnishing, advertising, automobile and other industries, and have developed rapidly in recent years. However, most foam boards have their own defects, and there are certain difficulties in the production process. For example, wall insulation materials need to be safe and durable. Security risks. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a highly stable foam board and a preparation method thereof. The foam board has high comprehensive performance, low cost and better market competitiveness. [0004] In order to solve the above technical solution, the present invention adopts the following techn...
