Abstract

The present invention discloses a building adhesive preparation method, which comprises: adding prepared a polyvinyl alcohol glue into a stirring tank, stirring at a temperature of about 80 DEG C, adding an acrylamide glue into the tank, stirring for 2 min, carrying out a shut-off reaction for 30 min, stirring, adding pure water, adding a polyacrylamide glue, stirring for 2-3 min, carrying out a shut-off reaction for 20 min, adding water, and stirring for 10 min so as to obtain the product. According to the present invention, the adhesive prepared through the method has characteristics of good performance, high bond strength, easy operation, no toxicity, no odor, fire resistance, and weather resistance.

Description

Technical field: [0001] The invention relates to the production technology of chemical products, in particular to a preparation method of construction viscose. Background technique: [0002] At present, with the continuous development of the construction industry, the construction decoration industry has also accelerated its progress along with the development of the main business. However, many of the adhesives used in buildings now contain chemical substances that are harmful to the human body, and many owners suffer from blood-type diseases after being violated and suffer all their lives. Moreover, many viscose are easily deformed, delaminated and peeled off due to changes in climate, which affects the decorative effect and causes environmental pollution. Invention content: [0003] The purpose of the present invention is to solve the problems existing in traditional building decoration viscose, and provide a kind of preparation method of building viscose, the viscose ...
