Summary of the invention
The object of the invention is to overcome weak point in prior art, compound flame-retardant expanded dose of a kind of mica is provided.
Compound flame-retardant expanded dose of mica is made up of sericite in powder, the Attapulgite potter's clay powder with air purification function, hydrogen peroxide, magnesium hydroxide, polyoxyethylenated alcohol sodium sulfate, micronized polyethylene alcohol powder, dimethyl silicone oil and water.
The production method that mica is compound flame-retardant expanded dose: first will stir as paste in compound mica flame-retardant expanded dose of paste batching input low-speed mixer, then will stir the finished product for compound flame-retardant expanded dose of mica in compound mica flame-retardant expanded dose of batching input homogenizer.
Mica has the characteristics such as good elasticity, toughness, insulativity, high temperature resistant, acid and alkali-resistance, corrosion-resistant, strong adhesion and satin luster, sericite has high resistance, excellent insulating material and fire-retardant filler, sericite can significantly change the series of physical modulus of material, form or change the visco-elasticity of material, this class material is absorbing vibrational energy, weakening shock wave and sound wave expeditiously, is used to prepare noise elimination, sound insulation, damping coating, and the present invention selects sericite.
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 sericite in powder and the batching such as Attapulgite potter's clay powder with air purification function, understand a large amount of bubble of generation.
Magnesium hydroxide is a kind of white amorphous powder, during by decomposes, discharge in conjunction with water, absorb a large amount of latent heat, reduce synthetic materials that it the fills surface temperature in flame, there is the polymer unwinds of inhibition and produced inflammable gas is carried out to cooling effect, decomposing the magnesium oxide generating is again good refractory materials, also can help to improve the fire resistance of synthetic materials, and the water vapour that it is emitted simultaneously also can be used as a kind of smoke suppressant; That magnesium hydroxide has is fire-retardant, press down cigarette, fill the outstanding fire retardant of triple functions.
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, and the film of formation 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 the compound flame-retardant expanded dose of production of mica.
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.
