Abstract

The present invention relates to amino resin intumescent aqueous flame retardant coating, in particular to an intumescent aqueous flame retardant coating. The present invention eliminates the releaseof harmful organic volatile compounds of the inflaming-retardant coating in use, improving poor fire resistant performance of dewatering catalyst due to a high disassembling temperature, solving theproblems of long manufacturing period, low efficiency and high cost of the inflaming-retardant wood materials. The materials for the present invention comprises amino resin, polyvinyl acetal resin, dewatering catalyst, melamine, charring agents, dope assistant, antifoaming agent, palette filling and water. The present invention has storage for a long time, good cohesion, slow and low emission of heat and low emission of smoke, enjoying good flexibility and good strike-resistant performance; furthermore, the present invention can be manufactured easily and used conveniently and can be easily popularized without emission of harmful organic volatile in use. Compared with a prior wooden inflaming-retardant liquid, the present invention has the advantages of simple process, convenient operation, low cost and high efficiency.

Description

technical field [0001] The invention relates to an intumescent water-based flame-retardant paint, in particular to a modified amino resin-based intumescent water-based flame-retardant paint for wood materials. Background technique [0002] At present, the amount of wood materials and coatings used in interior decoration is increasing year by year. Due to the flammability and flammability of wood materials and some paints, there must be a fire hazard. In recent years, due to the extensive use of decorative materials, such fires are on the rise. The preparation of new non-combustible, flame-retardant and low-toxic decorative materials has been highly valued by relevant state departments. [0003] Therefore, flame-retardant coatings (also known as fire-resistant coatings) have become a research hotspot. But existing flame retardant coatings still have some deficiencies: [0004] In the prior art of realizing flame retardancy on the base material through the catalytic carbon...
