Description
Technical field
The present invention relates to a kind of wooden, fiber, paper products combustion inhibitor special and preparation method thereof.
Background technology
Along with the development of Chinese synthetic material industry and the continuous expansion of Application Areas, fire retardant has vast market prospect in every field such as chemical building material, electronic apparatus, communications and transportation, space flight and aviation, household furniture, upholstery, clothing, food, lodging and transportion--basic necessities of life.In addition, fields such as coalfield, oil field, forest extinguishing have also promoted Chinese fire retardant, fire-fighting medium production to develop faster, and Chinese fire retardant has developed into the second largest polymer modification additive that is only second to softening agent.Present year output is between 150,000-170,000 t, and about year consumption 200,000 t, insufficient section is mainly from the U.S. and Israel's import, and the principal item of import is organic bromine and halogen-phosphorus flame retardant.China has the manufacturing enterprise of tame fire retardant more than 1000 at present, and Chinese fire retardant production is mainly bromine phosphorus series, and wherein bromide fire retardant is most important series, accounts for 30% of Chinese organic fire-retardant.
Along with the progress of science and technology and the raising of people's living standard, Home furniture, finishing degree of lignification such as floor is high more, and consequent disaster hidden-trouble threatens more and more serious, and the fire safety consciousness of entire society is increasingly high.Particularly the fire prevention and the safeguard protection of building in the style of the ancients and China minority name family wooden structures house (the pin building hangs in Miao ethnic group, the Dong nationality) seem more urgent.Especially a kind of when wooden, fiber, paper products are played the burning of fire retardation fire retardant demand non-volatile, that do not produce corrosive gases very urgent.
Fire retardant is the application of flame-retarded technology in real life, and it is a kind of special auxiliary chemicals that are used to improve flammable inflammable material combustionproperty, is widely used in the fire-retardant processing of all kinds of finishing materials.Through the material after the fire retardant processing, when receiving extraneous burning things which may cause a fire disaster and attack, can stop, delay or stop flame transmission effectively, thereby reach fire-retardant effect.
U.S. Pat 20050596731 through adding organophosphate and other components, like known fire retardant or conventional additives, with further flame retardant resistance or the stability improved, can make organic-polymer composition become to have flame retardant resistance.
The patent US20050200101 of the U.S. provides a kind of fire retardant that comprises multivalence oxybenzene compound, saccharide compound and fatty acid cpds, and a kind of fire-proof resin composition that contains said fire retardant and resin is provided.
The Chinese patent documents:
(97118353.8) one types of method for synthesizing flame retardant that are used for timber and other cellulose material of the compound method of wood fire retardant; Main employing Dyhard RU 100, phosphoric acid, boric acid and water are raw material; It is characterized in that Dyhard RU 100, phosphoric acid and water are 90 ℃ to the 120 ℃ synthetic guanyl-urea-phosphates of reaction down in temperature of reaction, then by guanyl-urea-phosphate and the composite fire retardant that makes of boric acid.
A kind of fire retardant and a kind of compound method that is used for the fire retardant of fabric of compound method (200710038826.7) thereof that is used for fabric is characterized in that: stir down Vanadium Pentoxide in FLAKES is dropped in the halo saturated fatty alcohol, be cooled with circulating water; Fully stir, be warming up to 60～70 ℃ again, insulation reaction is 2～3 hours under this temperature; Add NSC 446 then, and constantly stir, 90～110 ℃ of reactions 2～3 hours; Be cooled to room temperature, add water, fully stir after-filtration according to needed solid content; Filtrating is fire retardant, and wherein, the ratio of the amount of substance of raw material is: halo saturated fatty alcohol: Vanadium Pentoxide in FLAKES: NSC 446=2:1:2.
Summary of the invention
In order to overcome existing fire retardant to the single deficiency of fire-retardant product, the present invention provides a kind of wooden, fiber, paper products combustion inhibitor special and preparation method thereof.
The technical solution adopted for the present invention to solve the technical problems is: the invention discloses a kind of wooden, fiber, paper products combustion inhibitor special and preparation method thereof, it is to be formed by following preparation of raw material: two (diphenyl phosphoester) RDP20 of Resorcinol ~ 50%, triethyl phosphate (TEP) 20 ~ 35%, tricresyl phosphate (2 one chloropropyl) ester (TCPP) 15 ~ 36%, phenol A two (diphenyl phosphoester) (BDP) 10 ~ 28%, tensio-active agent 0.5 ~ 5%; The preferred mass per-cent of its moity is: two (diphenyl phosphoester) RDP30% of Resorcinol, triethyl phosphate (TEP) 25%, tricresyl phosphate (2 one chloropropyl) ester (TCPP) 18%, phenol A two (diphenyl phosphoester) (BDP) 22%, tensio-active agent 3%.
(BDP) reacting by heating of reacting by heating, tricresyl phosphate (2 one chloropropyl) ester (TCPP) and phenol A pair (diphenyl phosphoester) that the preparation method comprises two (diphenyl phosphoester) RDP of the preparation, Resorcinol of raw material and triethyl phosphate (TEP), the adding of tensio-active agent, the preparation of finished product.
Tensio-active agent fully plays in the surface tension that reduces fire-retardant medicament, the effect that increase invasive depth, improves carrying drug ratio.
The invention has the beneficial effects as follows: this a kind of wooden, fiber, its thermostability of paper products combustion inhibitor special is high, volatility is low; Good with the article consistency to not influence of fabric color; Intensity and the effect that also can not reduce fiber can not produce peculiar smell when using, not can with other chemical substance, pigment or top coat generation chemical reaction, help environmental protection; Making method is simple, and condition is easy to control.
