Phenolic foam board interface agent and preparation method thereof

Abstract

The invention discloses a phenolic foam board interface agent and a preparation method thereof. The phenolic foam board interface agent is prepared by mixing the following components of, by mass, 200-250 parts of 42.5 cement, 550-800 parts of coarse whiting, 50-100 parts of pulverized fuel ash, 40-80 parts of calcium hydroxide, 0.2-1 part of starch ether, 1-4 parts of cellulose, 1-5 parts of hydrophobic powder, 200-300 parts of acrylic acid emulsion and 300-400 parts of water. The phenolic foam board interface agent has the advantage that the bonding strength of the interface agent with a phenolic foam board is high, a protection layer can be formed on the surface of the phenolic foam board, the phenolic foam board can be prevented from erosion of natural phenomena such as weathering, ultraviolet rays and heavy rain wash, and the situation that due to the fact that efflorescence, cracking and deformation occur on the phenolic foam board, properties of the phenolic foam board are affected is avoided; the preparation method of the phenolic foam board interface agent has the advantages of being simple in technology and easy to implement.

Description

technical field [0001] The invention relates to a building bonding material, in particular to an interface agent for a phenolic foam board; the invention also relates to a preparation method of the interface agent for the phenolic foam board. Background technique [0002] Wall insulation is an important measure to achieve building energy conservation. The traditional insulation material mainly uses polystyrene board, which has the advantages of fast construction speed and unlimited construction height, but it also has the disadvantages of being easy to burn, not easy to stick and not sticky, etc. shortcoming. The relative phenolic foam board has the advantages of flame retardant, low smoke, low toxicity, and high temperature distortion resistance. It has been developed rapidly in recent years and has been widely used in the field of building energy conservation. [0003] Phenolic foam is a closed-cell thermosetting rigid foam, which belongs to organic foam insulation materi...
