Description
Technical field
The present invention relates to whipping agent, be specifically related to compound flame-retardant expanded dose of a kind of medical stone.
Background technology
Along with the reinforcement day by day of global safety environmental consciousness, people are more and more higher to the fire-retardant requirement of fire safety and 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 to be some fire retardants of representative with bromine system, phosphorus nitrogen system, nitrogen system and red phosphorus and compound, and inorganic mainly is 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.
Though fire retardant and whipping agent kind are many, use also extensivelyr, exist performance comprehensive inadequately, can not satisfy the drawback of actual production and environmental protection needs, the function that existing fire retardant and whipping agent do not purify air.
Summary of the invention
The objective of the invention is to overcome weak point in the prior art, compound flame-retardant expanded dose of a kind of medical stone is provided.
Medical stone is made up of medical stone powder, 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 for compound flame-retardant expanded dose.
The production method that medical stone is compound flame-retardant expanded dose: be paste with stirring in the compound flame-retardant expanded dose of paste batching of the medical stone input low-speed mixer earlier, be the compound flame-retardant expanded dose finished product of medical stone with stirring in the compound flame-retardant expanded dose of batching input homogenizer of medical stone again.
Medical stone is a kind of to biological nontoxic, harmless and have certain bioactive composite minerals or medicinal rock, and the main chemical compositions of medical stone is inorganic silico-aluminate.Medical stone has dual adsorptivity, be because it is based on silicate on the one hand, has good adsorptivity, on the other hand because medical stone contains clay minerals such as kaolinite more, it is the spongy special construction of porousness, strong electrostatic attraction is arranged, remain very strong adsorption, exchange interaction and adsorptivity; Medical stone have stronger adsorptive power to harmful several units such as cadmium, mercury, arsenic, lead, in water, to heavy metal ion with cause harmful toxin very strong adsorptive power is arranged, can remove objectionable impuritiess such as heavy metal such as mercury in the water, lead, cadmium, arsenic, fluorine and muriate, prussiate, residues of banned pesticides, leucoaurin.
Attapulgite potter's clay powder with air purification function is made up of the sticking attapulgite clay of height, attapulite constant humidity amendment, natural-minerals adsorptive filter medium, Leafy twigs of Oriental Arborvitae, aluminium silicate fiber peacekeeping polyacrylamide; Have cohesiveness, plasticity-, thixotropy, resistivity against fire and thermostability preferably; Effectively objectionable impuritiess such as formaldehyde, ammonia and benzene in the absorbed air are protected environment and are promoted the healthy of people.
High sticking attapulgite clay is the attapulgite clay that adopts the complete processing production that improves viscosity of attapulgite clay, attapulgite clay soil property exquisiteness, oily soapy is arranged, light weight, property are crisp, fracture is conchoidal or irregular shape, and water-absorbent is strong, tool viscosity and plasticity-when wet, its viscosity can reach more than the 3000mPas, is conducive to the bonding between the raw material.
High sticking attapulgite clay powder refers to get 28.0g attapulgite clay powder sample, add in the suspension cup of homogenizer, add 372g water again, the suspension cup is placed on the homogenizer, under 11000 rev/mins rotating speed, stirred 20 minutes, to pour in the beaker of 250ml the viscosity of using NDJ-1 type rotational viscosimeter to test its suspension, tested viscosity value 〉=2200 again through the high-speed stirring sample suspension into
MPasThe attapulgite clay powder.
