Problems solved by technology

Although the flame retardant adhesive coating of this system has certain flame retardant properties after textiles, it has certain shortcomings: the polyacrylate emulsion affects the flame retardancy of the flame retardant, and after igniting the flame retardant adhesive coated fabric, the polyacrylate Acrylate consumes part of the flame retardant, which reduces the flame retardant efficiency and increases the flame retardant cost of the fabric; when the polyurethane emulsion coating is applied to fabrics such as upholstered sofa fabrics and mattress fabrics, the fabric is easily burned through when ignited. The sponge or other fillings covered by it are also easy to ignite, unless the coating amount of flame retardant glue is increased to meet the flame retardant requirements at the expense of cost
[0004] 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 adhesive used for fabric coating, these flame retardant adhesives are coated on the fabric with BS-58252 1# fire source, 5# fire source test method, the fabric is very easy to be burned through , so as to ignite the sponge covered by the fabric, although it is possible to pass the test by increasing the coating amount of these flame-retardant adhesives, but the flame-retardant cost is relatively high

[0073] The preparation steps of described polyacrylate are as follows:

[0074] (1) Mixing of raw materials: Add hydroxyl-containing acrylic resin, 1-isocyanato-3-isocyanatomethyl-3,5,5-trimethylcyclohexane, dibutyltin dioctoate, tert- Dodecyl mercaptan is uniformly mixed in a certain proportion, and the usage amount of the dibutyltin dioctoate is 0.1wt%;

[0075] (2) Polymerization reaction: add a certain amount of toluene in the reaction vessel, heat to the reflux state, keep the reflux state, and add the monomer mixture dropwise at a uniform speed in the reaction vessel, and the dropwise addition is completed within 3 hours, then adjust the reaction material to 80 ℃, and keep warm for 1 hour;

[0076] (3) Post-treatment: Use atmospheric pressure and vacuum distillation to remove the solvent, pour the material into an aluminum tray while it is hot, and cool to obtain the polyacrylate.

[0077] In the present invention, the isocyanate group of the polyfunctional isocyanate ...

Abstract

The invention provides burnthrough-resistant water-based fire retardant glue for spinning. The burnthrough-resistant water-based fire retardant glue is prepared from the following components in parts by weight: 100 parts of a water-based adhesive, 10 to 100 parts of a halogen flame retardant, 3 to 100 parts of a synergistic flame retardant, 0 to 30 parts of an auxiliary and 0 to 100 parts of water, wherein the water-based adhesive is prepared from ethylene-vinyl acetate copolymer emulsion and an auxiliary adhesive; the solid content of the ethylene-vinyl acetate copolymer emulsion is 20 to 56 percent; the weight ratio of the water-based adhesive to the halogen flame retardant is (1 to 8) to 1; the halogen flame retardant is prepared from one or more of decabromodiphenyl ether, decabromodiphenyl ethane, tri(2,3-dibromo propyl) isocyanuric acid ester, tri(tribromophenyl) cyanurate, ethylene bis (tetrabromophthalimide), tetrabromo bisphenol A, hexabromocyclododecane, octo-bromo-ether, chlorine ester resin, ploy (vinylidene chloride) resin, brominated styrene, brominated epoxy resin, polyvinyl chloride, chlorinated paraffin and methyl chloride.

Description

technical field [0001] The invention relates to a flame-retardant coating adhesive for textiles, in particular, the invention provides a water-based flame-retardant adhesive suitable for fabrics with burn-through resistance. 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 fire. [0003] Traditional water-based flame-retardant...
