A kind of fiber latex composite adhesive and preparation method thereof

Abstract

The invention discloses a fiber latex composite adhesive, which comprises the following mass components: 50-90 parts of natural latex, 10-15 parts of heat-activated cotton fiber solution, 2-6 parts of catalyst, 5-6 parts of tackifier, 3~4 parts of plasticizer, 0.5~1 part of thickener, 0.2~0.5 part of defoamer. The present invention combines the heat-activated cotton fiber solution with natural latex, and the heat-activated cotton fiber will form a gel film to cover the natural latex particles during the compounding process, which can prevent the natural latex particles from interacting with other additives to a certain extent. Cross-linking occurs to reduce the self-bonding of the adhesive; at the same time, the present invention combines cotton fibers with good chemical structure stability and mechanical properties with natural latex to enhance the mechanical properties of the adhesive, and its effect is similar to that of steel bars in concrete. It can effectively improve the bonding strength of the adhesive.

Description

A kind of fiber latex composite adhesive and preparation method thereof technical field The invention belongs to adhesive preparation technical field, be specifically related to a kind of fiber latex composite adhesive and preparation method thereof Law. Background technique Natural latex is the latex collected from natural plants, and is mainly made of polyisoprene through filtration and coagulation. Composition of natural polymer compounds. The latex particles of natural latex are basically based on polyisoprene as the core and are The rubber component is surrounded by shells (such as proteins and lipids). From its chemical structure, it can be known that natural latex is a non-polar unsaturated rubber. The structure is not stable and the mechanical properties are poor. Natural latex is one of the main raw materials for preparing adhesive, and its chemical structure and mechanical properties directly affect adhesive The chemical structure stability and mechani...
