[0005] Secondly, the carbonization is not good. When the polyester fabric is coated with this kind of flame retardant adhesive, it is easy to burn through. Sponge padding behind sofa release, sparking fire
[0006] Chinese patent application number 93115328..X discloses a flame retardant coating that can be used for fabric coating, Chinese patent application number CN20048002553.X discloses a kind of flame retardant for general fabric coating, Chinese patent application number CN101498105 .B, announced a kind of flame-retardant glue that is used for fabric coating, and these flame-retardant glues are coated on fabric, and fabric is very easy to be burnt through, thereby ignites the sponge covered behind fabric, although increase these flame-retardant The coating amount of glue may also pass the test, but the flame retardant cost is higher
[0007] Chinese patent application number 201610907466.9 discloses a fire-resistant water-based flame-retardant adhesive for textile use. Although it does not contain antimony and is not easy to burn-through, however, after coating this water-based flame-retardant adhesive on the fabric, wash it with 40 ° C water After soaking for 30 minutes, the flame retardant performance decreased, and the burn-through resistance decreased extremely. Again, there was a phenomenon of melting dripping, and the melting dripping was very easy to burn and scald

Abstract

The invention belongs to the technical field of waterborne flame-retardant adhesives for fabric coatings and particularly relates to a method for preparing an antimony-free burnthrough-resistant waterborne flame-retardant adhesive for the fabric coatings. The method includes: step one, raw material preparation, to be specific, preparing, by weight, 20-40 parts of waterborne resin, 20-40 parts of aflame retardant, 2-10 parts of polyvinyl alcohol, 0.2-5 parts of auxiliary agents and 5-50 parts of water, wherein the total weight parts of the raw materials are 100. A finished product is preparedby procedures of polyvinyl alcohol solution preparation, powdery flame retardant aqueous dispersion preparation, phosphate flame retardant pretreatment, mixing and filtration. The method for preparingthe antimony-free burnthrough-resistant waterborne flame-retardant adhesive for the fabric coatings has advantages that without use of antimony trioxide, harms of residual heavy metals in antimony trioxide to human health are reduced; by adoption of polyvinyl alcohol as a carbonizing agent, excellent carbonization performance, burnthrough resistance and dripping resistance of fabrics are achieved, and the adhesive is especially applicable to the fabric flame-retardant coatings of mattresses, sofas, furniture covers, carpets, protective garments and the like.

Description

technical field [0001] The invention relates to the technical field of antimony-free water-based flame-retardant adhesive for fabric coating, in particular to a preparation method of antimony-free burn-through-resistant water-based flame-retardant adhesive for fabric coating. Background technique [0002] In recent years, with the progress of society and the improvement of people's living standards, the consumption of various civil and industrial textiles has increased rapidly, especially various interior decoration fabrics such as curtains, curtains, wall coverings, carpets, furniture cloth and bedding And the demand for tent fabrics and automotive interior fabrics is also increasing day by day. At the same time, the number of fires caused by textile fires has also continued to increase, causing serious economic losses and casualties. Therefore, it is very meaningful to reduce the loss of life and property by flame-retardant treatment of textiles to delay the spread of fir...
