Abstract

The invention discloses a novel wood fireproofing flame retardant and a preparation method thereof. The novel wood fireproofing flame retardant is composed of, by weight, 5-25 parts of pentaerythritol octahydrogen tetraphosphate, 10-25 parts of hyaluronic acid, 10-20 parts of polydopamine, 15-30 parts of ammonium metaborate, 3-9 parts of Span80, 5-15 parts of vermiculite, 7-15 parts of polycaprolactone, 3-8 parts of guar gum and 80-150 parts of water. The formula of the novel wood fireproofing flame retardant provided by the invention is reasonable, and the system has the good stability and compatibility through the polydopamine; and as a contained catechol functional group and the surface of a substrate material can form covalent bonding or noncovalent bonding, the flame retardant has super-high adhesivity to the surfaces of various materials, the compatibility with the materials is good, and the novel wood fireproofing flame retardant is non-toxic, environmentally friendly, good in flame retarding effect, low in cost, simple in preparation process and easy to apply and popularize widely.

Description

technical field [0001] The invention relates to the technical field of flame retardants, in particular to a novel wood fire-resistant flame retardant and a preparation method thereof. Background technique [0002] Wood is one of the four major building materials (reinforced steel, concrete, plastic, and wood). It has natural texture and gives people a sense of beauty. It is non-toxic and harmless, and is recognized as a renewable and environmentally friendly material. Wood and its products are favored by people for their unique charm of natural materials. Wooden furniture, wooden doors and windows, wooden floors and various wood products with good texture and beautiful shape have entered thousands of households, beautifying life and improving taste. It has gradually become a fashion that people pursue, and the market demand for wood is on the rise year by year. But wood is also a material that burns easily and presents a fire hazard. For this reason, wood materials must be...
