Environment-friendly flame-retardant adhesive for plywood and preparation method of environment-friendly flame-retardant adhesive

Abstract

The invention discloses an environment-friendly flame-retardant adhesive for plywood and a preparation method thereof. The environment-friendly flame-retardant adhesive is prepared from the following raw materials in parts by weight: 70 to 100 parts of urea resin, 10 to 25 parts of montmorillonite powder, 3 to 8 parts of magnesium hydroxide, 1 to 3 parts of phosphate, 0.5 to 1.5 parts of POSS, 5 to 10 parts of polyacrylamide, 10 to 30 parts of redispersible latex powder and 0.5 to 2 parts of a silane coupling agent. The urea-formaldehyde resin is used as a main material and matched with the montmorillonite powder, the flame retardant and other auxiliary materials, so that the prepared adhesive has the characteristics of high bonding strength, favorable flame retardancy, favorable water resistance, favorable moisture resistance and the like, can effectively lower the harm caused by formaldehyde and other toxic compounds, conforms to the requirements of the environment-friendly flame-retardant adhesive, and has favorable application prospects. Wide application prospects are realized in plywood processing.

Description

technical field

[0001] The invention relates to the technical field of adhesives, in particular to an environmentally friendly flame-retardant adhesive for plywood and a preparation method thereof. Background technique

[0002] The three major types of glue used in the traditional plywood processing industry: urea-formaldehyde resin, phenolic resin and melamine-formaldehyde resin, have the problem of releasing toxic aldehyde compounds during preparation, curing and use, which seriously pollute the environment and endanger human health. With the gradual enhancement of people's awareness of environmental protection and the improvement of national environmental protection laws and regulations, the development of non-toxic, non-polluting, green and environmentally friendly adhesives for plywood has become an inevitable trend in the development of the industry.

[0003] Urea-formaldehyde resin is the lowest price among synthetic resins due to abundant raw materials and low price....
