Description

Binder

The present invention relates to a kind of tackiness agent production method, particularly a kind of production method with mineral-type tackiness agent of higher bond strength.

Existing organic class adhesive bond strength is higher, becomes the direction of development.But unstable properties, as be heated come unglued, the machine solvent of meeting comes unglued, storage period is short etc., and in producing and using, exist very important drawback, as the toxic gas that volatilizees, have that the three wastes are drained, contaminate environment is more serious in producing, organic raw material is relatively more expensive simultaneously, and some need also very easily cause major accidents such as fire, blast from external import in the production.And the raw material ratio of mineral-type tackiness agent is more cheap, and is all low weight to the pollution of the harm of human body and environment, and production safety, but its bond strength is not as organic class tackiness agent height, and use range mainly is confined between the object of low bonding strength.So people's expectation provides, and a kind of energy is kept the safety in production, pollution is little, with low cost, the tackiness agent that bond strength is higher.

The objective of the invention is at the problems referred to above, a kind of production safety, harmless is provided, environmentally safe, raw material sources are extensive, with low cost, the higher and good mineral-type tackiness agent of use properties of bond strength.

Production method provided by the invention, water glass with cheapness is a major ingredient, add compositions such as properties-correcting agent, weighting agent, antioxidant, wetting Agent for Printing Inks, tackifier, thickening material and make, production method is as follows: at first with following component: solid-state water glass 30-60%(weight), potassium aluminium sulfate 0.05-10%(weight), Sodium Silicofluoride 0.01-5%(weight), high reactivity white lime 0.1-15%(weight), water 30-70%(weight)

Potassium aluminium sulfate in the said components can be substituted by the potassium chromium sulfate of weight percent 0.03-8% or be substituted by potassium aluminium sulfate that respectively accounts for weight percent 0.01-4% and potassium chromium sulfate.

Sodium Silicofluoride in the said components can be substituted by the magnesium silicofluoride of weight percent 0.01-5% or be substituted by Sodium Silicofluoride that respectively accounts for weight percent 0.01-3% and magnesium silicofluoride.

High reactivity white lime in the said components can be substituted by in zinc sulfide white, Walocel MT 20.000PV, titanium dioxide, the light calcium carbonate any, and weight percent is 0.1-15%; Perhaps by at least a substituting in high reactivity white lime and the said components, each weight percentages of components is 0.1-15%.

Each component is mixed in proportion in the input container, is heated to 100-150 ℃, be pressurized to the 0.5-0.7 MPa, reaction kept 30-60 minute, after sampling and testing is qualified, glue is discharged to gets supernatant liquor after leaving standstill in the subsider, drop into heated and stirred in the reactor, Heating temperature is 60-110 ℃.

The tackiness agent that is used for the woodenware class:

With supernatant concentration to 37-41 ° of Be '.

The tackiness agent that is used for leather, composite plate class:

Total amount adds the jelly powder of weight percent 0.03-2% and the tragacanth gum of 0.01-2% outward, is concentrated into 35-42 ° of Be '.

The tackiness agent that is used for trade mark:

Total amount adds the Semen Maydis powder of weight percent 0.05-5% or the starch of 0.03-5% outward, is concentrated into 35-43 ° of Be '.

The tackiness agent that is used for silicate products such as glass, pottery, marble, terrazzo, cement:

Total amount adds the copper sulfate of weight percent 0.05-5% and the ferrous sulfate of 0.05-5% outward, is concentrated into 40-45 ° of Be '.

Advantage of the present invention is: production and safe in utilization, and the no three wastes are drained, and do not have the volatilization toxic gas, raw material sources are wide, with low cost, bond strength is higher, and oxidation-resistance, erosion resistance, moisture-proof mildew resistance etc. are all more intense, easy to use, storage period is long, and naked light can not be lighted, and is safe and reliable, high-and low-temperature resistance has ideal social benefit and economic benefit.
