Problems solved by technology

Organic is some flame retardants represented by bromine, phosphorus nitrogen, nitrogen and red phosphorus and compounds, and inorganic is mainly antimony trioxide, magnesium hydroxide, aluminum hydroxide, silicon and other flame retardant systems; reactive type The flame retardant is used as a monomer to participate in the polymerization reaction, so the polymer itself contains flame retardant components. Its advantages are that it has little effect on the performance of the polymer material and has long-lasting flame retardancy; It will change the structure of paper, so additive flame retardants are often used; currently there is a special flame retardant for paper on the market, which is an environmentally friendly phosphorus-nitrogen flame retardant, but the pH value of the flame retardant is 5~6, The pH is low, the flame retardant is not firmly combined with the paper after spraying on the paper surface, and will fall off the paper surface after a period of time, and the paper is easy to yellow, which reduces the decoration and performance of paper weaving products
[0004] The existing patent document CN 103866614 A discloses a paper flame retardant and its preparation method. The obtained flame retardant has excellent flame retardant effect, but the added brominated resin will emit black smoke when it encounters high temperature or burns, and the resulting The gas is toxic and corrosive, causing great harm to the environment, and the obtained flame retardant is in the form of latex, which will make the paper hard when applied to the surface of the paper, which is not conducive to folding and weaving

Abstract

The invention mainly relates to the technical field of weaving article processing, and discloses a weaving paper spray flame retardant which is prepared from silicone modified phenolic resin, modifiedhigh density polyethylene, sodium silicate, sodium selenite, magnesium hydroxide, nano-graphene fibers, phytic acid and polyethylene glycol. The weaving paper spray flame retardant is green, healthy,safe and environmentally friendly, the heat resistance of paper can be increased, heat dissipation of the paper is accelerated, the carbonization time of the paper is prolonged, paper water absorption and toxic gas generation are avoided, the structures of the paper and a woven product are kept complete, and loss generated by combustion is avoided. The silicone modified phenolic resin is rapidlyheated and molten, slow heating and stirring are continued after the magnesium hydroxide is added, melt polymerization of the silicone modified phenolic resin and the magnesium hydroxide is promoted,the flexibility and flame resistance of the silicone modified phenolic resin are improved, excessive paper hardness caused by the flame retardant is avoided, and folding and weaving performances of the paper are kept.

Description

technical field [0001] The invention mainly relates to the technical field of weaving products processing, in particular to a spray-type flame retardant for weaving paper. Background technique [0002] Paper is widely used in people's life, writing, printing, sanitation, etc. are inseparable from paper, but it is rarely used for weaving, but as people's awareness of environmental protection and innovation continues to increase, more and more waste paper is used for weaving into handicrafts or daily necessities, but paper-woven products are extremely flammable, causing unnecessary economic losses. [0003] Flame retardants are functional additives that endow flammable polymers with flame retardancy. There are many types of flame retardants, which can be divided into additive flame retardants and reactive flame retardants according to the method of use; additive flame retardants are It is added to the polymer by mechanical mixing to make the polymer flame retardant. At presen...
