Description
Technical field
The present invention relates to a kind of adhesive and preparation method thereof, particularly to a kind of inorganic adhesive and preparation method thereof.
Background technology
Sodium silicate, is commonly called as sodium silicate, is a kind of water-soluble silicate, and its aqueous solution is commonly called as waterglass, is a kind of ore deposit adhesive.Its chemical formula is R2O·nSiO2, R in formula2O is alkali metal oxide, and n is the number that rubs of the ratio of silicon dioxide and alkali metal oxide molal quantity, referred to as waterglass.Architectural conventional waterglass is sodium silicate (Na2O·nSiO2) aqueous solution.Waterglass generally uses silica flour (SiO2) plus soda (Na2CO3), under the high temperature of 1300～1400 DEG C, calcining generates liquid sodium silicate, becomes granule from the outflow of furnace discharge mouth, clamp dog or shrend.Dissolve in high temperature or high-temperature high pressure water again, obtained solution shape waterglass product.In recent years, resistant to elevated temperatures environmental protection inorganic adhesive causes the common concern of people.
Inorganic adhesive is the viscosity that Organic substance macromolecule increases waterglass, and only in terms of viscosity angle, Organic substance macromolecule content waterglass within the specific limits remains to normally use；Content of organics within the specific limits time, it can increase the cementitiousness of waterglass, but when its content exceedes this prescribed limit constantly, and the cementitiousness of waterglass is declined slightly on the contrary.Along with production technology level improves constantly, inorganic adhesive uses field wider, and its market is the most increasing, and some high-performance, high-quality, high added value new product are gone into operation in succession.
At present, the most few about being developed the relevant information of inorganic bond by modified water glass.So-called modified water glass, it is simply that addition can change the material of waterglass characteristic on a small quantity in waterglass (sodium silicate), and it suffers from the most wide application prospect in industrial and agricultural production and daily life.Sodium silicate aqueous solution, can make adhesive and be used alone, but adhesive property and water resistance etc. are the most poor.So often adding some auxiliary materials in sodium silicate aqueous solution to improve its performance.Gelatin viscosity can be improved as added Sal；Addition carbamide, Borax, soda can improve adhesive strength；Addition casein, starch, sugar can improve adhesive strength and toughness；Add Calx and can improve resistance to water.
Summary of the invention
The present invention solves above-mentioned technical problem, a kind of inorganic adhesive of invention so that gained inorganic adhesive has high temperature resistant, fire-retardant, water-fast, and viscosity is good, nontoxic pollution-free, the effect of environmental protection.
A kind of inorganic adhesive, according to portion rate, comprises following components raw material:
Wherein, urea liquid is to take the urea granules of 1～6 part to put into dissolve in the water of 65～95 parts and form.
Wherein, described diluent is the one in ethanol, acetone.
Wherein, described filler is the one in mica powder, graphite powder, kaolin powder.
Wherein, described firming agent is prodan.
Wherein, described accelerator is SBS/SEBS antiseize resin Carity-120.
The preparation method of a kind of inorganic adhesive, comprises following operation:
(1) required each component raw material is weighed by portion rate；
(2) water intaking glass, glycerol epoxy resin, diluent are put in reactor, add filler, heating, start agitator simultaneously, make filler dissolve；
(3) adding urea liquid when temperature is 75～95 DEG C in reactor, the joining day is 30～60min, is subsequently adding firming agent and continues stirring with accelerator and 25～45min i.e. obtain product.
Compared with prior art, beneficial effects of the present invention:
The present invention, on the basis of inorganic adhesive waterglass, adds a small amount of urea liquid and glycerol epoxy resin, the inorganic bond developed so that it is has higher cohesive, and has heat-resisting quantity；Inorganic adhesive obtained by the present invention has high temperature resistant, fire-retardant, water-fast, the good nontoxic pollution-free of viscosity, the benefit of environmental protection, is more suitable for the theme of environmental protection now, and process of preparing of the present invention is simply, easily operate.
