Problems solved by technology

[0003] During the use of traditional floor adhesives based on water-based acrylic resins, the viscosity of the floor adhesives decreases due to long-term immersion in water, which makes the floor unable to be fixed. During the long-term use of the floor, the floor adhesives The toughening agent in the floor is continuously precipitated, which greatly reduces the toughness of the floor adhesive, which in turn causes cracks or breaks in the adhesive, making the floor unable to be fixed

Abstract

The invention discloses a floor adhesive based on water-based acrylic resin and a preparation process thereof. The floor adhesive is prepared from the following parts by weight of raw materials: 100-120 parts of modified water-based acrylic emulsion and 12-15 parts of toughening agent , 10-15 parts of thinner, 2-3 parts of talcum powder, 2-3 parts of asbestos powder, 2-3 parts of aluminum powder, 0.8-1.5 parts of anti-mold; The modified water-based acrylic emulsion and toughening agent are prepared in the process of preparing the floor adhesive. The modified water-based acrylic emulsion contains a large number of silicon-oxygen bonds on the molecules, and the bond energy of the silicon-oxygen bonds is far The bond energy is much higher than the carbon-carbon bond, which increases the water resistance of the prepared floor adhesive. A single toughening agent molecule contains multiple extremely polar cyano groups, which makes the toughening agent compatible with the modified water-based acrylic emulsion. When mixing, the blending effect of the two is improved, thereby increasing the service life of the adhesive.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and in particular relates to a floor adhesive based on a water-based acrylic resin and a preparation process thereof. Background technique [0002] Wood adhesives account for more than 60% of the total output of adhesives, and with the continuous development of the wood processing industry, the amount and varieties are increasing. The development of the adhesive industry has also had a positive impact on the development of the wood industry such as particleboard and fiberboard / plywood, enabling the full utilization of small-diameter grades, branch wood, thinning wood, and wood processing residues, improving the quality of wood. The comprehensive utilization rate improves the performance of wood. Adhesives have become a key link in determining the development level of particleboard and fiberboard production. The implementation of new processes in production, the improvement of production efficie...
