Abstract

The invention discloses a preparation method of an anti-yellowing halogen-free flame retardant applied to LED lampshades, and particularly relates to the technical field of flame retardant processing.The anti-yellowing halogen-free flame retardant comprises, by weight, 50-80 parts of aluminum hydroxide particles, 10-20 parts of a compatibilizer, 10-20 parts of ammonium polyphosphate powder, 5-10parts of triisopropylphenyl phosphate, 10-20 parts of dolomite powder, 20-40 parts of clay, 1-5 parts of benzoyl peroxide, 10-20 parts of an anti-yellowing agent and 60-100 parts of deionized water. The added aluminum hydroxide particles have the three functions of flame retardance, smoke abatement and filling, are nonvolatile and nontoxic, ad can generate a synergistic flame retardant effect together with various substances, so the flame retardant obtained in the invention has the advantages of improved flame-retardant effect, environmental friendliness, improvement of the yellowing resistance, simple preparation process, convenience in operation, and suitableness for being promoted and used.

Description

technical field [0001] The invention relates to the technical field of flame retardant processing, more specifically, the invention relates to a method for preparing a yellowing-resistant halogen-free flame retardant applied to LED lampshades. Background technique [0002] Flame retardant, a functional additive that imparts flame retardancy to flammable polymers, is mainly designed for the flame retardant of polymer materials. There are many types of flame retardants, which are divided into additive flame retardants and reaction Type flame retardants. After long-term use of the existing LED lampshades, the inner wall of the lampshades is prone to yellowing. Phosphorus compounds and metal hydroxides are the main additives for halogen-free flame retardants. These two types of compounds , does not volatilize and does not produce corrosive gases when burned, and is called a pollution-free flame retardant. In addition, there are several new types of halogen-free flame retardants ...
