Water-based flame-retardant coating adhesive and preparation method thereof

Abstract

The invention discloses a water-based flame-retardant coating adhesive and a preparation method thereof. The conventional flame-retardant coating adhesive adopts a gas-phase fire retardant as a main component, and fabrics cannot reach the BS-5852:2006 flame retardant test standard after being subjected to coating finishing by the conventional flame-retardant coating adhesive. The water-based flame-retardant coating adhesive comprises the following components in part by weight: 100 parts of waterborne base emulsion consisting of 30-60 parts of waterborne polyurethane emulsion and 40-70 parts of waterborne polyacrylate emulsion, 30-60 parts of a brominated flame retardant, 10-40 parts of polyhydroxylated compound, 5-10 parts of a phosphorus flame retardant, 5-20 parts of a flame retardant synergist, 5-10 parts of a thickening agent, 0.5 part of waterborne blocked isocyanate, and 0.3-0.5 part of a feeling agent. When the water-based flame-retardant coating adhesive performs coating finishing on fabrics, a continuous compact carbon layer is formed on the surface of the fabrics after flame occurs, so that the flame is effectively isolated, and the fabrics can reach the BS-5852:2006 flame retardant test standard.

Description

technical field [0001] The invention relates to a functional finishing agent for textiles, in particular to a water-based flame-retardant coating adhesive for textiles and a preparation method thereof. Background technique [0002] With the continuous development of the economy, industrial and civilian textiles are increasing rapidly, but at the same time, the fires caused by textiles are also increasing, which always threatens the safety of human life and property. Therefore, it is very meaningful to reduce the loss of life and property by flame-retardant treatment of textiles to delay the spread of fire. At present, industrially developed countries and regions have formulated corresponding textile flame retardant standards and test methods (such as the European Union's BS-5852:2006 flame retardant test standard for home textiles), and some countries have also issued relevant laws for enforcement. This has promoted the research on flame retardancy of textiles by industrial...

Problems solved by technology

However, it is difficult for their coated textiles to pass the BS-5852:2006 flame retardant test standard. The main reason is that although the Chinese patent application with application number 2013101605558 uses an intumescent flame retardant, it is applied to textile flame retardant coatings In the field of carbon layer, the carbonization effect is much worse than that in the plastic field. The carbon layer formed is not continuous enough to effectively isolate the flame, so it is difficult to pass the BS-5852:2006 flame retardant test standard; the Chinese patent application with application number 2008100631342 mainly uses gas phase The flame retardant is mainly used, and cannot form an intumescent carbon layer. The fabric is directly boiled when it encounters fire, and the flame directly contacts the sponge wrapped in the fabric. The sponge is flammable and cannot self-extinguish after being ignited, so it cannot pass the BS5852:2006 flame retardant test standard
