Oleyl alcohol polyether-2 phosphate modified waterborne alkyd flame-retardant resin and preparation method thereof

Abstract

The invention relates to oleyl alcohol polyether-2 phosphate modified waterborne alkyd flame-retardant resin and a preparation method thereof. The oleyl alcohol polyether-2 phosphate modified waterborne alkyd flame-retardant resin comprises the following components by weight: 20.0 to 42.0 part of vegetable oleic acid, 6.0 to 15.0 parts of oleyl alcohol polyether-2 phosphate, 3.0 to 6.0 parts of styrene, 4.0 to 8.0 parts of cyclohexanediol monoacrylate, 22.0 to 40.0 parts of dibasic acid, 25.0 to 52.0 parts of polyol, 10.0 to 20.0 parts of xylene, 8.0 to 15.0 parts of a solvent, 0.05 to 0.1 part of benzoyl peroxide, 2.5 to 5.0 parts of benzoic acid, 3.0 to 6.0 parts of dimethylolpropionic acid, 4.0 to 10.0 parts of a neutralizer and 100.0 to 200.0 parts of deionized water. According to theoleyl alcohol polyether-2 phosphate modified water-based alkyd flame-retardant resin prepared by the invention, oleyl alcohol polyether-2 phosphate is introduced into a branched chain, and the phosphorus element is not easily coated by macromolecular resin, so obvious flame-retardant effect is obtained; no flame retardant needs to be added when a flame-retardant coating is prepared, and flame-retardant effect is lasting; and the resin has the advantages of favorable adhesive force, favorable water resistance, favorable fullness, high corrosion resistance, favorable antibacterial properties andthe like.

Description

technical field [0001] The invention relates to a flame-retardant resin, in particular to an oleyl polyether-2 phosphate modified water-based alkyd flame-retardant resin and a preparation method thereof, belonging to the technical field of water-based resin synthesis. Background technique [0002] Alkyd resin is a kind of synthetic resin widely used in coatings, and it is also one of the most widely used synthetic resins in my country at present. It is cheap, easy to construct, rich in raw materials, low in acid value, soluble in various organic solvents, suitable for surface coating of all wood and metal, and has good wetting and dispersibility for pigments and fillers. The paint made of it has bright paint film, strong adhesion, good durability, excellent flexibility, gloss and fullness, and can be miscible with various synthetic resins. Alkyd resin paints with different properties can be obtained by modification . [0003] At present, only a few researchers in China hav...

Problems solved by technology

[0006] The above inventions all use phosphorus-based flame retardants, but the phosphorus element is located on the main chain of the alkyd resin, which is easily coated and affects its flame-retardant performance. At the same time, its performance is single. How to overcome the above shortcomings and prepare a flame-retardant Resin is a topic of great concern to the flame retardant coating industry
