Abstract
The present invention belongs to heat insulation and preservation materials for devices and buildings, and a production method thereof. The present invention is characterized in that composite silicate heat insulation and preservation paint is produced by various light nonmetallic minerals, and particularly, mountain cork is developed and applied; furthermore, a fiber paste form material containing hydrated magnesium aluminum silicate as a main component is produced by a wet process and a static electricity technology. Products of the present invention have the advantages of superior physicochemical performance, small thickness for use, convenient use for construction, good comprehensive economic result, simple production technology, less energy consumption, etc.; in addition, the present invention can be widely used for the heat insulation and preservation of devices, kilns, pipelines and buildings, the surface temperature of which is below 700 DEG C, and can also be used for sound isolation and fire prevention.
Description
The invention belongs to equipment or buildings used heat-insulation and heat-preservation material and production method thereof.
Existing heat-insulation and heat-preservation material can be divided into traditional material and type material two classes.Traditional material such as asbestos, vermiculite, diatomite, perlite, mineral wool and goods thereof etc.This class material unit weight is big, and thermal conductivity is big, constructing operation inconvenience, also contaminate environment that wherein has and injury human body.Type material such as aluminum silicate fiber, rock wool, glass wool, litaflex, microporous calcium silicate and goods thereof etc.This class material thermal conductivity is little, and materials thickness is thin slightly, but the production technology difficulty, the investment of founding the factory is high.No matter traditional material, or type material all exists energy expenditure many, and materials thickness is thick, constructing operation inconvenience, shortcomings such as comprehensive method of investment height.
Task of the present invention is, a kind of efficient, economic, free from environmental pollution, easy construction is provided, reaches a kind of heat-insulation and heat-preservation material and the production method thereof of energy-conservation purpose.
Theme of the present invention is through Chinese science and technology Institute of Social Science Information Chongqing branch international online retrieval, the patent documentation that does not provide a contrast.Product of the present invention and existing chemistry painting industry on using method roughly the same, all there is basic difference other aspects.
Product of the present invention is the fiber paste-like material that a kind of main component that is composited by multiple silicate minerals is the electrostatic of hydrous magnesium silicate aluminium.Its component and amount ranges (weight %) are: make orthopaedics with the positively charged ion chrysotile, consumption is 5.5-6.5; Make filler with multiple light body non-metallic minerals: mountain cork, alumina-silicate ceramic fibre, diatomite, wilkinite, pearlstone, total consumption is 3.8-4.4; Water consumption (not comprising the water yield in the tackiness agent) is 80-82; Anionic permeate agent consumption 1.2-1.32; Tackiness agent: by concentration is 6.25% polyvinyl alcohol water solution 6, and the sodium silicate aqueous solution 0.7 of concentration 40% and proportion are 1.8, and the aluminum phosphate solution 0.04 of PH=3 is formed.Wilkinite is done also can play thickening and adherent effect outside the filler usefulness.Mountain cork is a place of production title, do not name up to having both at home and abroad, and be that a kind of main component is the light body non-metallic minerals of hydrated aluminium silicate calcium magnesium.Its component is: aluminium sesquioxide 13%, silicon-dioxide 60%, magnesium oxide 4%, calcium oxide 4%, loss on ignition 17%.Be the extremely light (0.022-0.046 ton/m of a kind of unit weight
3), water-intake rate greatly (for the 3-18 of dry basis doubly), have micropore and elastic fibrous mineral.This mineral are still belonged to the first time as the heat-insulation and heat-preservation material.Product of the present invention becomes the closed porosity reticulated elastomeric material that a kind of solid substrate connects after use is heated or is poured into a mould drying.Pore opening, different.
Product processes of the present invention is taked wet work, uses electrostatic technique.Production technique can be divided into five stages: feedstock production, metering, immersion, stirring to pulp, leave standstill froth breaking.(1) feedstock production: the impurity elimination of loosening, classify of positively charged ion chrysotile, alumina-silicate ceramic fibre opener; Mountain cork is crushed to below 2 millimeters, and diatomite grog, wilkinite are pulverized-120 orders.(2) measure respectively by group component.(3) soak: positively charged ion chrysotile, alumina-silicate ceramic fibre, anionic permeate agent (part) are soaked with high-temperature water (95-100 ℃), and insulation is more than 24 hours.(4) stirring to pulp: add surplus (group component deducts consumption) anionic permeate agent and surplus (group component deducts and uses the high temperature water yield) water (normal temperature), stir more than 20 minutes, to becoming the foam pasty state.Add mountain cork, diatomite, wilkinite, pearlstone then, stir 3-5 minute to even.Add polyvinyl alcohol water solution, sodium silicate aqueous solution then, drink while stirring and add the phosphoric acid aluminum solutions, the potential of hydrogen that fiber is stuck with paste is measured on the limit, ends when being slight alkalinity (PH=7-8).(5) leave standstill more than 24 hours.The mechanism of action in the production process is: when soaking, utilize the different electrical gravitation with material of high-temperature water, strengthen the infiltration to fibrous magnesium silicate of permeate agent and water, short its acceleration is loosened.When stirring,, all be full of negative ion at the center and the outside surface of fibrous magnesium silicate because the permeate agent negative charge amount is considerably beyond asbestos positive charge amount.Under same sex charge repulsion and mechanical agitation, fibrous magnesium silicate is fully rationally loosened, make slip become electronegative fiber paste.Add several tackiness agent composite copolymerizations,, adapt to adherent requirement under the differing temps to increase denseness and the bounding force that fiber is stuck with paste.Control acid adhesive add-on is stuck with paste whole fiber and is slight alkalinity (PH=7-8).Take the measure of leaving standstill, allow its natural froth breaking (air pocket), reach steady state.
Product construction of the present invention is used and can be taked brush to smear or spraying method, and the also pourable goods that are dried to use.
Product of the present invention has good physicochemical property.Leave standstill under the normal temperature do not dewater, strong (coating is electronegative, the metal medium positively charged for not stratified, cohesive force, producing electrostatic attraction strengthens cohesive force greatly), no toxic dust, pollution-free, do not have a corrosion (hygrometric state coating is slight alkalinity, and acid is neutralized into neutrality during use and in the atmosphere).Product of the present invention is after use is heated or is poured into a mould drying, it is light to have unit weight, thermal conductivity is little, thermal stability height (700 ℃), chemical stability good (water-fast, oily, sour, alkali), flexible (can be flexible) with coated equipment or buildings, advantages such as nontoxicity (asbestos use and be heated after, become the forsterite fiber).
