A kind of pumice cement phenolic resin composite foam material and preparation method thereof

Abstract

The invention relates to a pumice stone, cement and phenolic resin composite foaming material. The pumice stone, cement and phenolic resin composite foaming material is prepared from the following components in parts by weight: 100 parts of phenolic resin, 35 to 45 parts of pumice powder, 20 to 30 parts of cement, 3 to 5 parts of surfactant, 6 to 9 parts of foaming agent, and 4 to 6 parts of curing agent. The pumice stone, cement and phenolic resin composite foaming material has the advantages that by organically combining inorganic matters and organic matters, the reliable strength and toughness of a product are guaranteed, the problem of poor heat insulation property caused by only use of the inorganic material is solved, the powdering condition of the prepared pumice stone, cement and phenolic resin composite foaming material is greatly relieved, and the toughness is enhanced; by arranging the cement and pumice powder surface and the phenolic foam surface, the cement and pumice powder surface is arranged at the outer surface of an outer wall, the phenolic foam surface is adhered with the wall base layer, the adhering strength is high, and the reliability and firmness are realized; the pumice powder and the cement are inflammable materials, so that a large amount of dispersed pumice powder and cement can provide double fireproof barriers, and the flame-retardant property of the phenolic foam is improved.

Description

technical field [0001] The invention relates to the technical field of thermal insulation foam materials, in particular to a pumice cement phenolic resin composite foam material and a preparation method thereof. Background technique [0002] Organic thermal insulation materials have excellent thermal insulation performance, but the problem of fire prevention is prominent. Compared with organic thermal insulation materials, the main advantages of inorganic materials are fire retardant, small deformation coefficient, anti-aging, stable performance, good ecological environmental protection, no consumption of organic energy, use of waste materials, better combination with wall base and plastering layer, and safety Good stability, long service life, small construction difficulty, low cost, etc. However, there are also problems such as large apparent density, poor compactness and processability, slightly poor thermal insulation performance, and poor water resistance. Therefore, ...
