Phenolic foam heat-insulation board for external walls of buildings

Abstract

The invention discloses a phenolic foam heat-insulation board for external walls of buildings. The phenolic foam heat-insulation board comprises main materials and auxiliary materials. A weight ratio of the main materials to the auxiliary materials is 1:0.2-0.5; the main materials comprise, by weight, 40-50 parts of phenolic foam plastics, 2-8 parts of glass wool, 5-15 parts of bisphenol A epoxy resin, 2-10 parts of cement, 5-10 parts of sawdust, 2-15 parts of asbestos fibers, 2-10 parts of silicon carbide, 5-10 parts of activated carbon, 1-5 parts of heavy calcium carbonate, 1-2 parts of sodium hexametaphosphate, 1-2 parts of sodium triphosphate and 50-100 parts of water; the auxiliary materials comprise, by weight, 5-15 parts of sodium silicate, 5-15 parts of rosin soap, 20-50 parts of modified sodium carboxymethyl celluloses, 1-2 parts of zinc oxide, 1-2 parts of copper oxide, 1-2 parts of chitin, 1-2 parts of mustard, 1-3 parts of lecithin, 1-2 parts of foam stabilizers and 1-2 parts of surfactants.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a phenolic foam thermal insulation board for building exterior walls. Background technique [0002] The energy consumption per unit area of ​​my country's buildings is 3 to 5 times that of developed countries. With the vigorous promotion and use of residential buildings, the use of external wall panels for insulation and decoration has been widely promoted and recognized. But at the same time, the mechanical properties, antibacterial and service life of the external wall panels are also in front of us. In recent years, due to the above reasons, the damage and aging of the internal wall panels of buildings have occurred in China, causing serious casualties and property losses. Insulation materials for exterior wall panels have become a new type of safety hazard. Therefore, upgrading the mechanical properties, antibacterial properties and service life of wall p...

But at the same time, the mechanical properties, antibacterial and service life of the external wall panels are also in front of us. In recent years, due to the above reasons, the damage and aging of the internal wall panels of buildings have occurred in China, causing serious casualties and property losses. Insulation materials for exterior wall panels have become a new type of safety hazard. Therefore, upgrading the mechanical properties, antibacterial and service life of wall panels for building interior walls has become an urgent problem to be solved.
