Abstract
The invention discloses a talcum composite flame-retardant foaming agent. The technical scheme is characterized in that the talcum composite flame-retardant foaming agent is prepared from talcum powder, attapulgite argil powder with an air purifying function, hydrogen peroxide, aluminum hydroxide, fatty alcohol polyoxyethylene ether sodium sulfate, ultrafine polyvinyl alcohol powder, dimethicone and water. Firstly, talcum composite flame-retardant foaming agent cream ingredients are mixed and stirred to form paste, and then fixed and stirred to form a finished product of talcum composite flame-retardant foaming agent. The talcum composite flame-retardant foaming agent and water are stirred at a high speed to forms porous foamed mud. Thus, a combustible material can be rapidly isolated from air, so as to reach the flame-retardant and fire-extinguishing targets. The product produced by the talcum composite flame-retardant foaming agent not only has the effects of heat preservation, thermal insulation and sound insulation, but also has the function of purifying the air; and the talcum composite flame-retardant foaming agent is can be used for producing fire-retardant light boards, light walls and noise-reduction products.
Description
Technical field
The present invention relates to whipping agent, be specifically related to compound flame-retardant expanded dose of a kind of talcum.
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 talcum is provided.
Compound flame-retardant expanded dose of talcum is made up of talcum 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.
The production method that talcum is compound flame-retardant expanded dose: first will stir as paste in compound talcum flame-retardant expanded dose of paste batching input low-speed mixer, then will stir the finished product for compound flame-retardant expanded dose of talcum in compound talcum flame-retardant expanded dose of batching input homogenizer.
Talcum is a kind of common silicate minerals, is irregular bulk, white, yellow-white or pale blue grey, odorless, tasteless, there is wax sample gloss, the soft exquisiteness of matter, hand touches with lubricious sense, no hygroscopicity, puts and in water, does not collapse loosely, and thermal insulation and insulativity are strong, and talcum powder is conventional products on building materials market.
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.
