Abstract

The invention discloses an environment-friendly building adhesive. The environment-friendly building adhesive is prepared from raw materials in parts by weight as follows: 80-97 parts of rosin glyceride, 25-32 parts of shellac, 172-186 parts of terpene resin, 24-57 parts of turpentine, 4-6 parts of aluminum silicate powder, 2-4 parts of white carbon black, 5-7 parts of zirconium hydrogen phosphate, 1-3 parts of tannin, 2-4 parts of potassium pyrophosphate, 6-8 parts of ethanol, 10-12 parts of hydroxyethyl cellulose, 5-9 parts of Arabic gum, 3-5 parts of potassium lactate, 2-4 parts of sodium lactate, 1-4 parts of sodium diacetate, 6-9 parts of silicon carbide whisker and 5-8 parts of butyl lactate. The environment-friendly building adhesive contains very little residual formaldehyde, doesnot affect human health and is favorable for environmental protection.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly building adhesives, and in particular relates to an environment-friendly building adhesive. Background technique [0002] Construction adhesive is an essential material in construction engineering and has a wide range of applications. With the development of economy, synthetic construction adhesives are increasingly used in various fields. In the process of building decoration and decoration, it is mainly used for plate bonding, wall pretreatment, wallpaper pasting, ceramic wall and floor tiles, various floors, carpet laying and bonding, etc., increasing waterproofness, sealing, elasticity, and impact resistance. This can not only improve the quality of architectural decoration, increase the aesthetic comfort, but also improve the construction process, improve the efficiency and quality of building construction, etc. [0003] Among the currently used adhesives, many are solvent-base...
