Description
Technical field
The present invention relates to whipping agent, be specifically related to compound flame-retardant expanded dose of a kind of Attapulgite.
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 take 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.
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 Attapulgite is provided.
Compound flame-retardant expanded dose of Attapulgite is made up of Attapulgite potter's clay powder, hydrogen peroxide, aluminium hydroxide, polyoxyethylenated alcohol sodium sulfate, micronized polyethylene alcohol powder, dimethyl silicone oil and the water with air purification function.
The production method that Attapulgite is compound flame-retardant expanded dose: first will stir as paste in compound Attapulgite flame-retardant expanded dose of paste batching input low-speed mixer, then will stir the finished product for compound flame-retardant expanded dose of Attapulgite in compound Attapulgite flame-retardant expanded dose of batching input homogenizer.
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, outward appearance is colourless transparent liquid, be a kind of strong oxidizer, the present invention selects massfraction >=35% of industrial hydrogen peroxide, after mixing, can generate a large amount of bubbles with the batching such as Attapulgite potter's clay powder and aluminium hydroxide with air purification function.
