[0025] The reaction preparation method in the above-mentioned adhesive comprises the following steps:

[0026] A. Preparation of seed emulsion: add deionized water and part of the emulsifier to form an emulsifier solution with a mass percent concentration of 0.10% to 0.14% in the stirring state of the polymerization kettle, and add nano-silica in the formed emulsifier solution Stir the aqueous sol for 10-30 minutes, then add the initiator solution prepared by the initiator with a mass percentage concentration of 0.80%-1.64%, and then keep warm for 15-30 minutes to obtain the seed emulsion;

[0027] B. Pre-emulsification of shell-layer mixed monomers: mix any one of acrylic acid and its ester monomers or methacrylic acid and its ester monomers with styrene monomers to form shell-layer mixed monomers, and shell The layer mixing monomer is divided into 6-8 parts by mass on average; the emulsifier, buffer and molecular weight regulator are evenly mixed and divided into 6-8 parts b...

Abstract

The invention discloses an adhesive for alkali resistant acrylate glass fiber mesh cloth shaping, and a preparation method thereof, and belongs to the field of polymer adhesive preparation. The adhesive is prepared through the reaction of the following components, wherein the components comprise: a material selected from acrylic acid and an ester monomer thereof, or methacrylic acid and an ester monomer thereof; nano-silicon dioxide; a styrene monomer; an initiator; an emulsifier; a buffering agent; a molecular weight regulator; a pH value modulator; and deionized water. According to the adhesive, the nano-silicon dioxide is adopted as the core, a copolymer of the styrene monomer and the acrylic acid monomer is adopted as the shell layer, and the shell layer hard monomer is the acrylate copolymer emulsion with the significant core-shell structure, wherein the concentration of the shell layer hard monomer shows the gradient change. The glass fiber mesh cloth treated by the adhesive of the present invention has advantages of excellent positioning effect, strong adhesive force, bright mesh cloth, good elasticity, high alkali resistance, good water resistance, strong weathering resistance, no yellowing, and no after tack. The adhesive of the present invention is the single mass component glue, is easy to use, does not contain any organic solvents, and has advantages of aquosity and environmental protection.

Description

technical field [0001] The invention belongs to the field of polymer adhesive preparation, and in particular relates to an alkali-resistant acrylic glass fiber grid cloth setting adhesive and a preparation method thereof. Background technique [0002] Glass fiber mesh cloth is also called alkali-resistant glass fiber mesh cloth. It is made of medium-alkali and non-alkali glass fiber woven fabrics with alkali-resistant treatment. This product has the advantages of high strength, good adhesion, obedience, and excellent positioning. It is widely used in wall reinforcement, inner wall or outer wall insulation, roof waterproofing, etc. It can also be used in the reinforcement of cement, asphalt, marble, mosaic and other wall materials. It is a new type of construction engineering material. It plays an important structural role in the thermal insulation system, mainly to prevent cracks. Due to its excellent acid and alkali resistance and high warp and weft tensile strength, it ca...
