Acid and alkali resistant chemical building adhesive

Abstract

The invention discloses an acid and alkali resistant chemical building adhesive which comprises the following components in parts by weight: 10-15 parts of oxalaldehyde, 80-100 parts of epoxy resin, 40-50 parts of furfural-acetone resin, 5-10 parts of acetone, 10-15 parts of ethidene diamine, 5-7 parts of alumina, 100-120 parts of quartz powder and 8-10 parts of polyvinyl alcohol. The preparationmethod comprises the following steps: (1) uniformly mixing circular resin and furfural-acetone resin, and heating to a temperature of 45 DEG C; (2) adding acetone and ethidene diamine to be uniformlystirred; (3) adding alumina, quartz powder, oxalaldehyde and polyvinyl alcohol, and heating to a temperature of 59 DEG C. The chemical building adhesive prepared by the method disclosed by the invention has high bonding strength. The chemical building adhesive prepared by the method disclosed by the invention is specially prepared for chemical buildings, has excellent corrosion resistance, and isapplicable to corrosion prevention of the chemical buildings, acid and alkali resistant pools and bonding and gap filling of porcelain plates and ceramic tiles. The used materials are environmental-friendly products. The acid and alkali resistant chemical building adhesive is wide in applicability, can be matched with Portland cement or building plaster and is capable of bonding various lightweight boards.

[0002] At present, construction glue is used in every process and even every material in the construction industry. It can be divided into the following aspects: application in various building constructions, indoor and outdoor decoration and decoration, and sealing of various buildings. , including doors and windows, large board walls, expansion joints, joints, etc., applications in building maintenance, renovation, reinforcement and reinforcement, reinforcement and maintenance of various transportation facilities and water conservancy projects, widely used in the development direction of composite building materials, Mixed with cement to make a variety of high-performance concrete, this type of application can provide high-performance basic materials for construction, and solve many problems such as high-strength and quick-drying that traditional materials cannot achieve. The construction adhesive used in chemical construction is due to its use environment It is special and has higher requirements for construction adhesives, but commercially available construction adhesives have problems of insufficient bonding strength, insufficient acid and alkali resistance, and easy aging.
