Abstract

The invention relates to a chemical assistant, and concretely relates to a fire retardant. The fire retardant comprises, by weight, 7-10 parts of coated red phosphorus, 40-50 parts of aluminum hydroxide, 10-30 parts of magnesium hydroxide and 5-10 parts of talcum powder, wherein coated red phosphorus is microencapsulated red phosphorus, and the particle size of the microencapsulated red phosphorus is smaller than 100[mu]m; aluminum hydroxide is nano-modified aluminum hydroxide, and the particle size of the nano-modified aluminum hydroxide is smaller than 100[mu]m; and magnesium hydroxide is nano-modified magnesium hydroxide, and the particle size of the nano-modified magnesium hydroxide is smaller than 100[mu]m. The fire retardant has the advantages of reasonable formula, non-toxicity and innocuousness, low cost and good fire retardation effect.

Description

A kind of fire retardant
Technical field
The present invention relates to a kind of auxiliary chemicals, be specifically related to a kind of fire retardant.
Background technology
Along with the development of Chinese synthetic material industry and the continuous expansion of Application Areas, fire retardant has wide market outlook in the 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, the field such as coalfield, oil field, forest extinguishing also promotes that China is fire-retardant, fire-fighting medium is produced and developed faster.China fire retardant developed into the second largest polymer modification additive being only second to softening agent, current throughput 200,000 about t/a, year output between 150,000-17 ten thousand t, year consumption 200,000 about 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 1000 Duo Jia fire retardant manufacturing enterprises at present, and Chinese fire retardant is produced and is mainly bromine phosphorus series, and wherein bromide fire retardant is most important series, accounts for 30% of Chinese organic fire-retardant.
The kind of domestic fire retardant and consumption are still based on organic fire-retardant, and inorganic combustion inhibitor production and consumption amount is also less, but the development in recent years impetus is better, and market potential is larger.Although halogenated flame retardant the most frequently used in fire retardant has the unrivaled high efficiency of other fire retardant series, it is very important to the harm of environment and people.Environmental issue is the focus that auxiliary agent development and application business pays close attention to, so adjusting the product structure of fire retardant both at home and abroad always, strengthens the exploitation of Efficient environment-friendlyflame flame retardant.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the technical deficiency that the harm to environment and the mankind of halogenated flame retardant in prior art is large, provide the environment friendly flame retardant of a kind of Halogen, low cigarette, low toxicity, good flame retardation effect.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A kind of fire retardant, its weight part consists of: encapsulated red phosphorus 7-10 part, aluminium hydroxide 40-50 part, magnesium hydroxide 10-30 part, talcum powder 5-10 part.
Further, described encapsulated red phosphorus is microencapsulated powder oil, and the particle diameter of described microencapsulated powder oil is less than 100 μm.
Further, the preparation method of described microcapsule red phosphorus is as follows: 300ml water, 50g red phosphorus, 30g Tai-Ace S 150 and 10g flocculation agent are added in there-necked flask and stir 30 minutes, red phosphorus is uniformly dispersed in the solution, the sodium hydroxide solution slowly dripping 10% wherein regulates pH to be 5-6, stop dripping, by solution 60-65 DEG C insulation two hours, coating layer is fully condensed, deposit after carry out suction filtration, wash with dispersion agent.Put into baking oven 100-120 DEG C drying 24 hours, namely obtain required microcapsule red phosphorus.
Further, the size of described microencapsulated powder oil is 80 μm.
Further, described aluminium hydroxide is ATH, and the particle diameter of described modified aluminium hydroxide is less than 100nm.
Further, described aluminium hydroxide is ATH, and the particle diameter of described modified aluminium hydroxide is 80nm.
Further, described magnesium hydroxide is nano modification magnesium hydroxide, and the particle diameter of described modified magnesium hydroxide is less than 100nm.
Further, described magnesium hydroxide is nano modification magnesium hydroxide, and the particle diameter of described modified magnesium hydroxide is 80nm.
The present invention adopts the object of encapsulated red phosphorus to be: in the agent of phosphorus fire-retardant, the flame retardant effect of red phosphorus is best, flame retarding efficiency is the highest, because red phosphorus theory is phosphorus simple substance completely, phosphorus content can reach 100%, and coated after red phosphorus moisture absorption and processing heat stability stronger, storing and also more convenient in transport.
The present invention adopts aluminium hydroxide, the object of magnesium hydroxide is: the cheap and fire retardant material burning of aluminium hydroxide, magnesium hydroxide does not produce a lot of smog, h substance mainly water and carbonic acid gas etc. can not cause the material of very major injury to environment, belong to environmental type product, share with red phosphorus, make the flame retardant effect of fire retardant better.
Employing the invention has the beneficial effects as follows: the present invention fills a prescription rationally, nontoxic, cost is low, good flame retardation effect.
