Description
Technical field
The present invention relates to whipping agent, be specifically related to flame-retardant expanded dose of a kind of coal ash compound type.
Background technology
Along with the reinforcement day by day of global safety environmental consciousness, people are more and more higher to fire safety and the fire-retardant requirement of goods, and the environment friendly flame retardant of Halogen, low cigarette, low toxicity has become the target that people pursue.
Fire retardant mainly contains organic and inorganic at present, halogen and non-halogen.Organic is some fire retardants taking bromine system, phosphorus nitrogen system, nitrogen system and red phosphorus and compound as representative, and inorganic is mainly the flame-retardant systems such as antimonous oxide, magnesium hydroxide, aluminium hydroxide, silicon system.
Whipping agent can be divided into chemical foaming agent, pneumatogen and tensio-active agent three major types, and the many whipping agents of purposes have cement blowing agent, concrete foamer, plastics blowing agent, polyurethane foams, rubber pange agent, glass whipping agent etc.
Although fire retardant and whipping agent kind are many, apply also extensivelyr, exist performance comprehensive not, can not meet the drawback of actual production and environmental protection needs, the function that existing fire retardant and whipping agent do not purify air.
Flyash is to receive and catch the thin ash getting off in the flue gas from coal combustion, flyash is the main solid waste that coal-burning power plant discharges, flyash is one of industrial residue that the current discharge capacity of China is larger, and along with the development of power industry, the flyash quantity discharged of coal-burning power plant increases year by year.A large amount of flyash does not add processing, will produce airborne dust, atmosphere pollution; Can cause river to silt up if enter water system, and toxic chemical substance wherein also can work the mischief to human body and biology.
Summary of the invention
The object of the invention is to overcome weak point in prior art, flame-retardant expanded dose of a kind of coal ash compound type is provided.
Flame-retardant expanded dose of coal ash compound type is made up of flyash, the Attapulgite potter's clay powder with air purification function, hydrogen peroxide, aluminium hydroxide, polyoxyethylenated alcohol sodium sulfate, micronized polyethylene alcohol powder, dimethyl silicone oil and water.
The production method that coal ash compound type is flame-retardant expanded dose: first will stir as paste in flame-retardant expanded coal ash compound type dose of paste batching input low-speed mixer, then will stir the finished product for flame-retardant expanded dose of coal ash compound type in flame-retardant expanded coal ash compound type dose of batching input homogenizer.
Fly ash grain is multi-hole type cellular tissue, and specific surface area is larger, has higher adsorption activity, and Zhu Bi has vesicular structure, and porosity, up to 50%-80%, has very strong water-absorbent.
The Attapulgite potter's clay powder with air purification function is made up of the sticky attapulgite clay of height, attapulite constant humidity amendment, natural-minerals adsorptive filter medium, Leafy twigs of Oriental Arborvitae, aluminium silicate fiber peacekeeping polyacrylamide; There is good cohesiveness, plasticity-, thixotropy, resistivity against fire and thermostability; The effectively objectionable impurities such as formaldehyde, ammonia and benzene in absorbed air, protection of the environment and promote the healthy of people.
High sticky attapulgite clay is the attapulgite clay that adopts the complete processing that improves viscosity of attapulgite clay to produce, attapulgite clay soil property exquisiteness, there is oily soapy, light weight, property are crisp, fracture is conchoidal or irregular shape, and water-absorbent is strong, tool viscosity and plasticity-when wet, more than its viscosity can reach 3000mPas, be conducive to the bonding between raw material.
High sticky attapulgite clay powder refers to gets 28.0g attapulgite clay powder sample, add in the suspension cup of homogenizer, add again 372g water, suspension cup is placed on homogenizer, under the rotating speed of 11000 revs/min, stir 20 minutes, to pour in the beaker of 250ml through high-speed stirring sample suspension again the viscosity that uses NDJ-1 type rotational viscosimeter to test its suspension, tested viscosity value>=2200 into
mPasattapulgite clay powder.
Hydrogen peroxide is commonly called as hydrogen peroxide, and outward appearance is colourless transparent liquid, is a kind of strong oxidizer, and the present invention selects massfraction >=35% of industrial hydrogen peroxide.After mixing with carbide slag and the batching such as Attapulgite potter's clay powder with air purification function, understand a large amount of bubble of generation.
Aluminium hydroxide can not only be fire-retardant as fire retardant, and can prevent from being fuming, do not produce dropping, do not produce toxic gas.
Polyoxyethylenated alcohol sodium sulfate is soluble in water, has good decontamination, emulsification, foam performance and anti-performance of hard water, is a kind of anion surfactant.
Micronized polyethylene alcohol powder is a kind of white, powdery, stable, nontoxic high molecular weight water soluble polymer, can be dissolved in fast in normal-temperature water, forms stable colloid, and water is the solvent that polyvinyl alcohol is good.Polyvinyl alcohol has the good film of making, the film forming has excellent adhesion, solvent resistance, rub resistance, tensile strength and oxygen barrier performance, can improve the viscosity of foam, there is certain steady bubble effect, and can improve the product bulk strength that adopts flame-retardant expanded dose of production of coal ash compound type.
Dimethyl silicone oil surface tension is little, water insoluble, chemical stability is good, nontoxic, be a kind of defoamer and remover, the invalid bubble generating for eliminating foaming process, improve the make rate of abscess, also help cast quick demoulding and prevent from the mould that collapses from carrying out flame-retarding fire-extinguishing for fire-extinguishing location when foam materials, can not add dimethyl silicone oil.
