Problems solved by technology

However, if the amount of flame retardant added is small, the flame retardant effect is not ideal; when the added amount increases, the flame retardant effect will become better, but because the flame retardant cannot be combined with the resin, and the water resistance of the amino resin itself is not good, so it is made The performance of wet curtain products becomes worse, and the water resistance becomes worse, which seriously affects the use of wet curtains

Abstract

The invention provides an amino resin composition for a flame-retardant wet curtain and a preparation method and application thereof. The flame-retardant wet curtain consists of amino resin, flame-retardant resin and an additive, wherein the flame-retardant resin is prepared from a hydroxy-containing aromatic compound, a nitrogenous compound, an ester derivative of phosphate, a polyol, an acid catalyst, aldehyde, a basic catalyst and an organic solvent. According to the invention, flame-retardant resin is added into an amino resin composition to obtain the amino resin composition for the flame-retardant wet curtain, and the prepared amino resin composition for the flame-retardant wet curtain can be applied to production of wet curtains in any process and of any base material, and the obtained wet curtains have not only excellent flame retardant property but also remarkably improved performance and waterproofness.

Description

technical field [0001] The invention belongs to the technical field of flame retardant resin and its preparation, and relates to an amino resin composition for a flame retardant wet curtain, a preparation method and application thereof. Background technique [0002] The wet curtain is a cooling facility that uses the principle of water absorption-evaporation-heat absorption after the base material is impregnated with resin, corrugated, cured, and cut. Phenolic resin is the best performance and is currently the most widely used impregnation resin. Amino resin is an impregnating resin second only to phenolic resin. Amino resin is similar to phenolic resin in performance, but because amino resin is easily hydrolyzed at high temperature, it is far inferior to phenolic resin in water resistance. [0003] The base material of the wet curtain can be made of water-absorbent textiles such as paper, cotton cloth, and non-woven fabric. Among them, paper is the cheapest and most widely...
