Abstract

The invention discloses an organic montmorillonite and an application thereof. The invention firstly modifies the montmorillonite to obtain the organic montmorillonite, thereby preparing an adhesive. Among them, organic montmorillonite plays the role of protective colloid and emulsification in the process of vinyl acetate copolymerization. The layered montmorillonite is dispersed in the polymer matrix and has the characteristics of good storage stability, uniform dispersion and strong interfacial binding force. At the same time, montmorillonite is an inorganic flame retardant, which has the advantages of excellent mechanical properties, gas barrier and flame retardant effect, low cost, and convenient processing. It not only improves the mechanical properties of polymers, but also opens up a new way for polymer flame retardants. .

Description

technical field [0001] The invention relates to an adhesive preparation technology, in particular to an organic montmorillonite and its application. Background technique [0002] Water-based polyvinyl acetate adhesive is currently one of the most widely used and used environmentally friendly adhesives. It is obtained by emulsion polymerization with water as the dispersion medium, and is a water-based environmentally friendly adhesive. It is widely used in wood, furniture, decoration, printing, textiles, etc. , leather, paper and other industries, is a very environmentally friendly adhesive. Fast drying, good initial tack, good workability; strong adhesion, high compressive strength; strong heat resistance. Widely used in semi-outdoor and outdoor particleboard, plywood, laminated wood and wood cold-setting finger joints. These plywood boards are widely used in the manufacturing process of wooden doors and other furniture. The boards have large format, many varieties, good...
