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 of the floor adhesive. The floor adhesive is prepared from the following raw materials in parts byweight: 100 to 120 parts of modified waterborne acrylic emulsion; 12 to 15 parts of toughening agent; 10 to 15 parts of diluent; 2 to 3 parts of talcum powder; 2 to 3 parts of asbestos powder; 2 to 3parts of aluminum powder; and 0.8 to 1.5 parts of mildew preventive. When the floor adhesive is used, the floor adhesive and an isocyanate curing agent are mixed according to the mass ratio of 3: 1;the modified water-based acrylic emulsion and the toughening agent are prepared in the preparation process of the floor adhesive; molecules of the modified water-based acrylic emulsion contain a largenumber of silicon-oxygen bonds; the bond energy of the silicon-oxygen bond is far higher than that of carbon-carbon bonds, so that the water resistance of the prepared floor adhesive is improved; anda single toughening agent molecule contains a plurality of cyano groups with extremely strong polarity, so that the blending effect of the toughening agent and the modified water-based acrylic emulsion is improved when the toughening agent is mixed with the modified water-based acrylic emulsion, and therefore, the service life of the adhesive is further prolonged.

Description

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