preparation example Construction

[0017] The preparation method of the above-mentioned urushiol phosphorus-based flame-retardant resin includes: separating and extracting urushiol from raw lacquer according to a conventional method, then adding a formulated amount of solvent to obtain an urushiol solution, and then adding a formulated amount of amine compounds to the urushiol solution , aldehyde compounds and catalysts, heated to 60-100°C, reacted for 2-6 hours, raised the temperature to remove the small molecule product water; ℃, react for 1 to 4 hours, stop heating and cool down to room temperature to obtain the urushiol phosphorus-based flame-retardant resin.

[0018] The urushiol is extracted from lacquer produced in Ankang, Hanzhong, Chengkou, Maoba, Qinling or other areas, with a frying fraction of more than 65% and a urushiol content of more than 50%.

[0019] The phosphorus compound is one or more of phosphorus oxide, phosphorus oxychloride, and phosphate ester.

[0020] The amine compound is one or m...

Abstract

The invention discloses urushiol phosphorous-series flame retardant resin. The resin consists of the following raw materials in percentage by mass: 20 to 40 percent of urushiol, 0 to 20 percent of amine compound, 4 to 10 percent of aldehyde compound, 0.5 to 6 percent of phosphorous-series compound, 0 to 5 percent of epoxy resin, 0.5 to 3 percent of catalyst and 40 to 55 percent of solvent. A method for preparing the urushiol phosphorous-series flame retardant resin comprises the following steps of: obtaining raw lacquer from a lacquer tree; separating and extracting the urushiol from the raw lacquer, heating the urushiol and reacting the heated urushiol with the amine compound, the aldehyde compound, the solvent and the catalyst for synthesizing; and adding the epoxy resin, the phosphorous-series compound and the solvent into the complex, heating and reacting for synthesizing, stopping heating and cooling to room temperature after reaction is finished. The resin has high flame retardant property, water resistance and chemical resistance and is suitable for fields such as public fire safety, chemical industry, light industry, building materials, electronic apparatuses, mining and the like.

Description

technical field [0001] The invention relates to a flame-retardant coating, in particular to an urushiol phosphorus-based flame-retardant resin and its preparation, which is mainly used in the fields of public fire safety, chemical industry, light industry, textile, building materials, electronic appliances, mining and the like. Background technique [0002] my country is rich in raw lacquer resources, and there are many kinds of coatings made by using raw lacquer. With the rapid development of social economy, people's requirements for the flame retardant performance of coatings are increasing day by day, and the demand for flame retardant coatings in various fields is also more diverse. New The use of flame retardant materials in the field of national economy complies with the instructions of the central government on "preventing problems before they happen". It is the premise to ensure the safety of people's lives and national resources. The demand for combustion products is ...
