Abstract

The invention relates to a preparation method of a graphene modified flame-retardant waterborne polyurethane coating and adhesive. The preparation method comprises the following steps: preparing a flame-retardant MOFs compound from MOFs, preparing a flame-retardant MOFs dispersion liquid from the flame-retardant MOFs compound, and finally preparing the polyurethane coating and adhesive from polymer polyol, isocyanate, dibutyltin dilaurate and the flame-retardant MOFs dispersion liquid. The effect of improving the two important indexes of flame retardance and static prevention of the polyurethane coating and the adhesive is outstanding.

Description

technical field

[0001] The invention relates to the field of functional polymer materials, in particular to a method for preparing graphene-modified flame-retardant water-based polyurethane coatings and adhesives. Background technique

[0002] Since the 1950s, my country began to develop and apply polyurethane coatings. With the continuous improvement and improvement of the material living standards of the general public, the development speed of a series of industries such as automobile processing, furniture manufacturing and processing, petrochemical industry, machinery industry, bridge and shipbuilding has been continuously increasing. With its outstanding performance advantages, polyurethane coatings have entered a new stage of rapid development. According to statistics, from 1980 to 2004, the use of polyurethane coatings in various industries has shown a very rapid development trend. The total use of polyurethane coatings has achieved a breakthrough development from 0....
