Problems solved by technology

However, the combination of two finishing agents has to face the problem of compatibility of the finishing agents. The final product performance may be different from that of the single finishing. There may be interactions between chemical substances, chemical substances and fabrics, thereby changing the properties of the fabric itself.

Abstract

The invention relates to an acrylate polymer integrating water and oil repellence with flame retardancy, which has the structural formula shown as the figure, and preparation and application thereof. The preparation of the acrylate polymer comprises the steps: at first, chlorine alkyl phosphate and alkyl alcohol amine are subject to ammonolysis reaction under certain conditions, the resultant alcohol is further subject to esterification reaction with acryloyl chloride at low temperature to prepare acrylate derivative consisting of phosphorus and nitrogen units, and finally the acrylate derivative, fluorine-containing acrylate, crosslinking monomer and long-chain acrylate monomer are subject to polymerization through emulsion. The acrylate polymer according to the invention can be diluted with water at any ratio, has no bioaccumulation toxicity, no or low VOC discharging and no formaldehyde and other harmful substances, and is an environmentally friendly, green, pollution-free water / oil-resisting antifouling flame-retardant finishing agent with high performance; in addition, the acrylate polymer not only can be used for the flame-retardant finishing of fabrics, but also has excellent water and oil repellence and eco-friendliness.

Description

technical field [0001] The invention belongs to the field of acrylate polymers, preparation and application, in particular to an acrylate polymer with integrated water-repellent, oil-repellent and flame-retardant properties, its preparation and application. Background technique [0002] At present, a lot of attempts have been made in the water and oil repellent finishing of fabrics. Fluorine-containing acrylate polymers contain perfluoroalkyl groups on the side chains, and the perfluoroalkyl side chains are oriented outwards, so their surface free energy is low, and they have good water and oil repellency, while acrylates have high The molecule itself has the characteristics of good film-forming property and relatively loose network structure, so the fabric treated with fluorine-containing acrylate fabric finishing agent can obtain excellent waterproof, oil-proof, anti-fouling, breathable, moisture-permeable characteristics and good chemical stability , thermal stability an...
