Abstract

The invention relates to the technical field of building materials and particularly relates to a building adhesive with high bonding strength and acid-alkaline resistance and a preparation method thereof. The building adhesive is prepared from the following components in parts by weight: isopropyl acetate, urea formaldehyde resin, stearyl amine, starch, alpha-cellulose powder, chloroprene rubber,phenol, a crosslinking agent, a dispersing agent, a wetting agent, a thickening agent and proper amount of deionized water. The building adhesive prepared by the invention has the advantages of high bonding strength and chemical-corrosion resistance and the like; due to equal-mass mixing and synergistic action of paraffin and calcium stearate, all the raw materials can be uniformly dispersed in solution, so that the uniformity of the mass of the adhesive is ensured; due to mixing of the urea formaldehyde resin, aluminium sulfate and aluminium phosphate, the water resistance of the urea formaldehyde resin can be improved, and due to the action of the starch and the alpha-cellulose powder, the shrinkage rate of the urea formaldehyde resin can be reduced; in addition, due to equal-mass addition and mixing of xanthan gum and guar gum, the synergistic action can be largest, so that the salt resistance, the acid-alkaline resistance and the bonding strength of the adhesive can be enhanced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a building adhesive with high bonding strength and acid and alkali resistance and a preparation method thereof. Background technique [0002] Adhesive bonding refers to the technology of connecting the surfaces of homogeneous or heterogeneous objects with adhesives. It has the characteristics of continuous stress distribution, light weight, or sealing, and most of the process temperature is low. Gluing is especially suitable for the connection of different materials, different thicknesses, ultra-thin specifications and complex components. Glue is developing the fastest in modern times and has a wide range of application industries. There are many classification methods of adhesives, which can be divided into thermosetting type, hot melt type, room temperature curing type, pressure sensitive type, etc. according to the application method; according to the application o...
