Problems solved by technology

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.
In order to solve the flammability problem of PP, IFR is gradually applied to polyolefin materials such as polypropylene (PP), and the carbon sources used are mostly pentaerythritol and its series, but the char formation effect in PP is not very ideal, and it has a Disadvantages such as temperature difference, poor water resistance, and easy migration limit the application range of IFR in PP

Abstract

The invention relates to a sulfur-containing macromolecule triazine polymer and a preparation method thereof. The structural formula of the compound is shown in the description, wherein N is larger than 1, X is alkylamine, and Y is dialkylamine. The preparation method comprises the steps that alkylamine is equimolarly added into a solution of triglycidyl isocyanurate with stirring, then, the temperature is increased to a certain temperature, and a reaction is performed for a period of time to enable pH of the solution to reach 7-8; a certain mole of dialkylamine is added, the temperature is increased to a certain temperature, a heat-insulated reaction is performed for a period of time to enable pH of the solution to reach 7-8, suction filtration is performed for solvent recycling after cooling, then, washing, drying and smashing are performed, and therefore the sulfur-containing macromolecule triazine polymer is obtained. The sulfur-containing macromolecule triazine polymer is the good flame retardant charring agent, has the charring anti-drop effect, can be well compatible with high polymer materials, and is good in heat and water resistance, excellent in processing performance and capable of being as the flame retardant charring agent for polyethylene (PE), polypropylene (PP), silicone rubber and other materials; the raw materials are cheap and easy to obtain, the production cost is low, equipment investment is small, the production process is simple, and large-scale production is easy.

Description

technical field [0001] The invention relates to a sulfur-containing macromolecular triazine polymer and a preparation method thereof. The compound can be used as a carbon forming agent for materials such as polyethylene (PE), polypropylene (PP), and silicon rubber. Background technique [0002] With the rapid development of our country's economy and the continuous improvement of people's living standards, polymer materials have been widely used. Because of their flammability, they often cause fires and pose a serious threat to people's lives and properties. In order to prevent or reduce the damage caused by fire, people are constantly looking for various new high-efficiency halogen-free and environmentally friendly flame retardants. Among them, the intumescent flame retardant (IFR) is a kind of compound environmental protection green flame retardant mainly composed of nitrogen and phosphorus. It does not contain halogen and does not use antimony oxide as a synergist. The sys...
