preparation example Construction

[0033] In the preparation of the interface agent of the present invention, the mixing temperature is preferably carried out at normal temperature. In the present invention, the rotational speed of the shearing machine required for mixing the components is 600-1200r / min, preferably 700-1100r / min, more preferably 800-1000r / min.

[0034] In the preparation method of the interface agent according to the present invention, in the detection of the pH value of the third mixed solution, when the pH of the third mixed solution is 6.5-8, no pH regulator needs to be added; when the third mixed solution When the pH value of the mixed solution is less than 6.5, an alkali pH regulator is used as the pH regulator; when the pH value of the mixed solution is greater than 8, an acidic pH regulator is used as the pH regulator.

[0035]The interface agent provided by the invention has excellent water resistance and durability when applied to organic thermal insulation materials. At the same time...

Abstract

The invention provides an interface agent for a foam insulation board. The interfacial agent comprises, by weight, 100 parts of macromolecule emulsions, 1-30 parts of acid curable adhesives, 10-50 parts of flame retardants, 0.1-2 parts of water repellents, 20-60 parts of self-crosslinking type adhesives, 0.1-5 parts of thickener and 0-5 parts of pH modifiers. The acid curable adhesives perform curing by the aid of acidity of the foam board and provide chemical crosslinking for the interfacial agent and the board, and durability of the interfacial agent is improved; the macromolecule emulsions and the acrylic acid polymer self-crosslinking type adhesives are mixed for using, so that film formation of the interfacial agent is good, water permeating is stopped, water resistance of the interfacial agent is improved, and the acid-base reaction between the foam insulation board and cement mortar is prevented; and the interfacial agent is provided with a flame retardant function through the addition of the flame retardants into the interfacial agent.

Description

technical field [0001] The invention relates to the technical field of interface agents, in particular to an interface agent used for foam insulation boards. Background technique [0002] With the rapid development of urbanization, the construction of new buildings is increasing year by year, so the amount of thermal insulation materials used in buildings is also increasing year by year. [0003] At present, building insulation materials are mainly divided into inorganic insulation materials and organic insulation materials. Inorganic thermal insulation materials such as rock wool, glass wool, foam glass, microporous calcium silicate, hydrophobic perlite, etc. have good fireproof properties, but their thermal conductivity is large, and the thermal insulation effect is not ideal, so it is difficult to meet the requirements of national energy-saving standards. , so the scope of application in the insulation system is very narrow. Organic thermal insulation materials such as ...
