Abstract

The invention relates to a triazine macromolecular halogen-free flame-retardant char-forming agent compound and a preparation method thereof. The structure of the compound is as shown in the description, wherein n is larger than 1, X is alcohol amine, and Y is dialkylamine. The preparation method comprises the steps that under the stirring condition, an equimolar amount of alcohol amine is added into a solution of triglycidyl isocyanurate, the temperature is increased to a certain value, and heat preservation reaction is conducted for a period of time to enable the pH of the solution to range from 7 to 8; a certain molar of dialkylamine is added, the temperature is increased to a certain value, and heat preservation reaction is conducted for a period of time to enable the pH of the solution to range from 7 to 8; cooling is conducted, suction filtration (recycling of solvent), water washing, drying and smashing are conducted, and the triazine macromolecular flame-retardant char-forming agent product is obtained. The triazine macromolecular halogen-free flame-retardant char-forming agent is an excellent flame-retardant char-forming agent, has a char-forming anti-dropping effect, is good in compatibility with high molecular materials and excellent in processability and can be used as the flame-retardant char-forming agent of materials such as polyethylene (PE), polypropylene (PP) and silicone rubber; the raw materials of the char-forming agent are low in price and easy to obtain, the production cost is low, the equipment investment is low, the production technology is simple, and scale production is easy.

Description

technical field [0001] The invention relates to a triazine macromolecule halogen-free flame-retardant char-forming agent compound and a preparation method thereof. The compound can be used as a char-forming agent for materials such as polyethylene (PE), polypropylene (PP), and silicon rubber. Background technique [0002] Polypropylene (PP) is the most widely used and the largest output of the two general-purpose plastics. Because of its odorless, non-toxic, tasteless, good physical and chemical stability, low density, excellent electrical insulation, and convenient processing, it is used in the automotive industry, household It is widely used in electrical appliances, electronics, wire and cable, packaging and building materials. However, PP is an extremely flammable material, and the char formation rate is almost 0, and it is easy to melt and drip, which limits the application field of PP. As people's awareness of environmental protection continues to increase, stricter r...
