Problems solved by technology

But unfortunately, although these kinds of adhesives are all technologies developed and used for flooring, they have not been specifically researched or disclosed in terms of long-term high temperature resistance, high pressure performance, flame retardant insulation, etc., and have been tested by the applicant. After use, it is found that the bonding strength is also unsatisfactory

Abstract

The invention provides an adhesive for a fast heating floor and a preparation method and application thereof. The preparation method comprises the following preparation steps of: mutually dissolving dibutyl phthalate and octanol to obtain a dissolving solution; heating water to 70 DEG C, adding polyvinyl alcohol and starch to the water, and increasing temperature to 90 DEG C till the polyvinyl alcohol and the starch are all dissolved; reducing the temperature to 70 DEG C, and adding vinyl acetate to obtain a dissolved paste; adding the dissolving solution to the dissolved paste, adding ammonium persulfate, a reinforcing agent and borax, and carrying out emulsion polymerization at 70 DEG C to obtain the adhesive. The using method comprises the following steps of: diluting the adhesive; coating the adhesive to an adhering surface for adhesion; solidifying after the adhesion. An undiluted adhesive can also be directly used. The fast heating floor adhered through the adhesive provided by the invention has the advantages of high temperature resistant property, high pressure resistant property, bonding strength property, flame-retardant insulating property and good stability.

Description

technical field [0001] The invention relates to an adhesive and its preparation and application. In particular, a special adhesive for heating floor and its preparation method and application method. Background technique [0002] With the improvement of people's quality of life, there are more and more cases of using heating floors as heating in household or work production environments. Because the use of heating floors is not limited by central heating, and the heating temperature in all corners of the space is uniform , deeply loved by those who pursue a high-quality life. [0003] The production of heating floors is not easy, especially for fast-heating floors, because the floors are all bonded by multiple layers of materials with various functions. Adhesives are used for bonding. It will affect or even destroy the adhesive, which will damage the bonding structure of the floor. The heating floor is different according to the settings of each manufacturer, and generall...
