Post-treatment of cement cloth

The wetting agent on the surface of cement cloth will have a certain adverse effect on the adhesion of polyurethane resin coated with glass fiber belt. The cement cloth can be cured by post-treatment and coated with suitable coupling agent to improve the adhesion between glass fiber and polyurethane resin.

The effect of glass fiber coated felt

Acrylic emulsion has the advantages of high adhesion, good film-forming ability, no organic solvent and no pollution, and has been widely used in the field of fabric coating. The polymer prepared by common emulsion copolymerization of glass fiber coated felt has the disadvantage of "hot and sticky, cold and brittle", while the copolymer of "soft core and hard shell" prepared by core-shell polymerization method can give full play to the advantages of "soft core" softness and "hard shell" non-adhesion. By adding organosilicon coupling agent to copolymer with cool monomers of acrylic acid, introducing organosilicon group or polysiloxane chain on the molecular chain of cool polymer of acrylic acid to make it have high weather resistance, water resistance, stain resistance and other properties of organosilicon resin. By using the crosslinking of organosilicon coupling agent, the densification of film formation is increased and the water-resistance and alkali resistance performance is improved. The organic silicon coupling agent is hydrolyzed to produce light base, which can condense with the light base on the surface of glass fiber, improve the adhesion between polymer and glass fiber, and increase the positioning effect.
