Embodiment 1

[0067] Put 100 parts by weight of polypropylene resin (Zhenhai Refining & Chemical Co., Ltd., HMS20Z, heat distortion temperature under 0.45 MPa load: 110°C) and 2 parts by weight of talcum powder into a high-speed mixer and mix thoroughly, and the resulting mixture is fed into the single-screw extruder through the feeding port , Control the die temperature at 135°C and the pressure at 12MPa. The blowing agent carbon dioxide was injected into the polypropylene resin composition melt at a pressure of 10 MPa through the blowing agent injection port installed on the barrel of the extruder. Then the melt is extruded through a circular hole die with a diameter of 2mm, foamed, pelletized, cooled and dried to obtain expanded polypropylene beads with a foaming ratio of 45 times.

Abstract

The invention relates to a phenolic resin composition and a foaming material and a moulding material prepared therefrom in the field of high molecular materials. The phenolic resin composition comprises solid phenolic resin, a phenolic resin foaming agent, foaming resin beads and rubber particles, wherein the foaming basic resin used for the foaming resin beads is resin, the heat distortion temperature of which is higher than 90 DEG C at a load of 0.45 MPa. The foaming material provided by the invention comprises a crosslinked foaming phenolic resin matrix and the foaming resin beads and rubber particles dispersed in the crosslinked foaming phenolic resin matrix and is prepared from the phenolic resin composition. The foaming material has low heat conductivity coefficient and excellent flame retardant property. The moulding material prepared from the foaming material can be used as an insulating material, a soundproof material, a shock-reducing material, a wood-imitation material and the like which are not combusted if encountering with an open fire.

Description

technical field [0001] The invention relates to the field of polymer materials, and furthermore, relates to a phenolic resin composition and the foaming material and molding material prepared therefrom. Background technique [0002] Because of the high energy consumption of buildings, energy conservation and heat preservation of buildings is a necessary measure in the current situation of increasingly tense energy sources. [0003] Phenolic foam insulation material has good flame retardant effect, does not drip, does not burn, and does not emit toxic and harmful gases under open flame conditions, that is, it has the properties of non-combustible, smokeless, and non-toxic when exposed to open flames, but it is brittle and easy to pulverize. Make transportation and construction all have certain difficulty, limit its application. [0004] The method currently used is to form a composite foam material with phenolic foam and polystyrene foam to prepare a thermal insulation mater...
