Abstract
A novel inorganic adhesive comprises components as follows: 60-70 parts of sodium silicate, 5-10 parts of glycerol epoxy resin, 4-6 parts of a urea solution, 10-17 parts of a diluent, 12-20 parts of filler, 9-13 parts of a curing agent and 4-9 parts of an accelerant. A preparation method comprises steps as follows: placing the sodium silicate, the glycerol epoxy resin and the diluent into a reactor, adding the filler, heating the mixture, and meanwhile, starting a stirrer to dissolve the filler; adding the urea solution to the reactor at the temperature of 75-95 DEG C for 30-60 min, then adding the curing agent and the accelerant, and continuously stirring the mixture for 25-45 min to obtain the inorganic adhesive. The prepared inorganic adhesive has the advantages that the inorganic adhesive is high-temperature-resistant, flame-retardant, waterproof, good in viscosity, non-toxic, pollution-free and environment-friendly and is more suitable for the green and environmental protection theme nowadays, and the preparation method is simple and easy to operate.
Description
Technical field
The present invention relates to a kind of tackiness agent and preparation method thereof, particularly a kind of inorganic adhesive and preparation method thereof.
Background technology
Water glass, is commonly called as sodium silicate, and be a kind of water-soluble silicate, its aqueous solution is commonly called as water glass, is a kind of ore deposit tamanori.Its chemical formula is R
2onSiO
2, R in formula
2o is alkalimetal oxide, and n is the ratio of silicon-dioxide and alkalimetal oxide mole number, is called the number that rubs of water glass.Architectural conventional water glass is water glass (Na
2onSiO
2) the aqueous solution.Water glass adopts silica powder (SiO usually
2) add soda ash (Na
2cO
3), under the high temperature of 1300 ~ 1400 DEG C, calcine produce liquid water glass, become particle 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 water glass product.In recent years, resistant to elevated temperatures environmental protection inorganic tackiness agent causes the common concern of people.
Inorganic adhesive is the viscosity that organism polymer increases water glass, and only from viscosity angle, organism polymer content within the specific limits water glass still can normally use; Organic content within the specific limits time, it can increase the viscosifying power of water glass, but exceedes this specialized range constantly when its content, and the viscosifying power of water glass slightly declines on the contrary.Along with production technology level improves constantly, inorganic adhesive uses field also more and more wider, and its market is also increasing, and some high-performance, high-quality, high added value product innovation are gone into operation in succession.
At present, about few really by the relevant information of modified water glass development inorganic adhesive.So-called modified water glass, in water glass (water glass), add the material that can change water glass characteristic on a small quantity exactly, it has extremely wide application prospect in industrial and agricultural production and daily life.Sodium silicate aqueous solution, can make tackiness agent and be used alone, but adhesiveproperties and water resistance etc. is all poor.So often add some subsidiary material to improve its performance in sodium silicate aqueous solution.Gelatin viscosity can be improved as added salt; Add urea, borax, soda ash can improve bonding strength; Add casein food grade, starch, sugar can improve bonding strength and toughness; Add lime and can improve water tolerance.
Summary of the invention

Wherein, described filler is the one in mica powder, Graphite Powder 99, kaolin powder.
Wherein, described solidifying agent is Sodium Silicofluoride.
Wherein, described promotor is SBS/SEBS antiseize resin Carity-120.
A preparation method for novel inorganic tackiness agent, comprises following operation:
(1) required each component raw material is taken by portion rate;
(2) reactor put into by water intaking glass, glycerol epoxy resin, thinner, adds filler, and heating, starts agitator simultaneously, filler is dissolved;
(3) in reactor, add urea soln when temperature is 75 ~ 95 DEG C, the joining day is 30 ~ 60min, then adds solidifying agent and namely obtains product with promotor continuation stirring 25 ~ 45min.
Compared with prior art, beneficial effect of the present invention:
The present invention, on the basis of inorganic adhesive water glass, adds a small amount of urea soln and glycerol epoxy resin, develops novel inorganic adhesive, makes it have stronger binding property, and has high thermal resistance; Inorganic adhesive obtained by the present invention has the benefit of high temperature resistant, fire-retardant, water-fast, the good nontoxic pollution-free of viscosity, environmental protection, be more suitable for the theme of environmental protection now, and process of preparing of the present invention is simple, easy to operate.
