Flame retardant containing flame-retardant synergistic composition and preparation method thereof

Abstract

The invention discloses a flame retardant containing a flame-retardant synergistic composition and a preparation method thereof. The flame retardant comprises the following raw materials by weight: 10-30 parts of organic silicon, 3-6 parts of melamine, 5-8 parts of triethyl phosphate, 10-13 parts of triphenyl phosphate, 6-9 parts of trichloroethyl phosphate, 1-4 parts of tributyl phosphate, 7-10 parts of hydroxyl polysiloxane, 4-7 parts of sodium methoxide, 70-100 parts of water, 5-20 parts of strong base, 3-6 parts of dibutyltin dilaurate, 10-30 parts of a flame-retardant synergistic composition, 5-20 parts of 2, 2-dihydroxymethyl-3-nitro-1-propanol, and 5-8 parts of an acid binding agent. The preparation method comprises the following steps: S1, raw material weighing: weighing the aboveraw materials through an electronic scale for standby use; and S2, mixed reaction: reacting the triethyl phosphate, triphenyl phosphate, trichloroethyl phosphate, tributyl phosphate, hydroxyl polysiloxane and water prepared in S1. The prepared flame retardant containing phosphorus and nitrogen is wide in application, and the flame retardant properties of the flame retardant can be improved throughthe flame-retardant synergistic composition.

Description

technical field [0001] The invention relates to the field of flame retardants, in particular to a flame retardant containing a flame retardant synergistic composition and a preparation method thereof. Background technique [0002] Polyester, epoxy resin, etc. can be flame-retardant processed by using additive flame retardants or introducing flame-retardant monomers into the molecules. The additive flame retardant is directly mixed with the resin, which is easy to process and has a wide range of applications. It is the main body of the flame retardant; the reactive flame retardant is often bonded to the polymer chain as a monomer, which has little effect on the performance of the product and is flame retardant. The effect is long-lasting; commonly used flame retardants are divided into halogen flame retardants, nitrogen flame retardants, phosphorus flame retardants, silicon flame retardants, intumescent flame retardants, inorganic fillers, etc. At present, organophosphorus f...

Problems solved by technology

In order to obtain a better flame retardant effect, the addition of phosphate flame retardants and phosphorus oxide flame retardants is relatively large. At present, the existing flame retardants are not effective and the manufacture is complicated. Therefore, we propose a A flame retardant containing a flame retardant synergistic composition and a preparation method thereof are used to solve the above problems
