Problems solved by technology

[0003] During the production process, urea-formaldehyde glue is made by heating and stirring in a stirring tank, but when discharging, because the colloid is in a viscous state, a large amount of urea-formaldehyde glue is adsorbed on the inner wall of the stirring tank and it is difficult to discharge, resulting in waste of glue and increased costs. , and after the artificial particle board synthesized by urea-formaldehyde glue is installed, it is easy to be eaten by moths during long-term use, resulting in a reduction in the service life of the artificial particle board

Abstract

The invention provides an artificial particle board adhesive and a production method thereof, and relates to an artificial particle board adhesive and a production method thereof in the field of artificial particle board production. The adhesive is prepared from 600-700 parts by weight of formaldehyde, 35-45 parts by weight of melamine, 6-14 parts by weight of camphor oil, 200-220 parts by weight of urea, 600-650 parts by weight of a caustic soda solution, 200-300 parts by weight of an ammonium chloride solution, 3-7 parts by weight of sodium cellulose, 3-7 parts by weight of ammonia water and 3-7 parts by weight of polyvinyl alcohol. According to the invention, the moth-proof capability of the urea-formaldehyde glue can be improved by adding the camphor oil, the artificial particle board glued by the urea-formaldehyde glue has a moth-proof function during use, the artificial particle board cannot be corroded by moths after long-term use, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of artificial particle board production, in particular to an artificial particle board adhesive and a production method thereof. Background technique [0002] Urea-formaldehyde glue is a wood-based panel made of wood or wooden poles, broken logs, fine wood fibers on both sides, long wood fibers in the middle, and glued under the action of heat and pressure after applying adhesive. The section presents a honeycomb-like sheet. The adhesive used is urea-formaldehyde glue. [0003] In the production process of urea-formaldehyde glue, it is made by stirring the heating and stirring tank, but when discharging, because the colloid is in a viscous state, a large amount of urea-formaldehyde glue is adsorbed on the inner wall of the stirring tank, which is difficult to discharge, resulting in waste of glue and increased cost. , and the artificial particle board synthesized by urea-formaldehyde glue is easily corroded by moths...
