Abstract

An adhesive suitable for cement, wood, ceramic, paper, steel, glass and plastics contains components A and B, and is prepared by mixing them together. A and B all are adhesive. The B is a colour-less transparent one and has stronger adhesion to said materials. Its advantages include easily available raw materials, low cost, easy application, high adhesion, and short solidifying time. The workpieces bound with the adhesive can resist against water, saline, and the solution of strong acid or weak alkali.

Description

Tackiness agent

The present invention relates to a kind of tackiness agent.It sticks into one with a lot of materials such as cement, timber, ceramic tile, paper, steel, glass, plastics, pottery etc., and stronger cohesive force is arranged, and has extremely strong sealing water proof and preservative activity.

It has the good adhesion performance tackiness agent, various materials can be sticked into securely the material of one.Tackiness agent can divide (one) natural materials such as animal skin glue, gelatine etc. (two) high molecular synthetic material from material, as the normal temperature cured adhesive, epoxy glue, alpha-cyanoacrylate ester gum (three) mineral compound material such as phosphoric acid salt, silicate etc. are arranged.The present invention seeks to a kind of seccotine stick.The starting material that the present invention is used and last different, tackiness agent A component it neither simple high molecular synthetic material, it or not again simple mineral compound material, it is by fiery molecular compound and mineral compound solubilizing agent, additive and make after reacting, performance is highly stable, avoided macromolecular compound to grow with time and aging becoming fragile, the B component is formed with aromatic solvent, No. 30 petroleum ether dissolutions by polymer rubber body and porous plastics, sylvic acid etc.Though because its bonding of A component, anticorrosion, the water proof ability is all fine, it exists extensibility to still have some deficits, the temperature resistance ability is not more than 60 ℃, in order to improve above shortcoming, after A component and B component are miscible, can improve significantly and extend and the temperature resistance ability.

Abundant raw materials of the present invention is easy to get, and cost is low, and price is general tackiness agent Manufacturing process is not too complicated, and easy to use, set time is shorter.Cohesive force is stronger, be particularly suitable for not only requiring the bonding jail, and require long term operation in water, salt solution, strong acid, weakly alkaline solution after the bonding, and have anticorrosion and the sealing impermeable role, component B tackiness agent has stronger cohesiveness to cement, ceramic tile, timber, paper, plastics, steel, glass etc.

Tiling glue requires to solidify at several minutes, so increase oxidized bitumen, wilkinite, suitably reduces clarified oil, owing to require solvent to volatilize fast, make ceramic tile paste the jail, therefore adopt the most volatile more No. 30 sherwood oils, in order to improve the heatproof requirement of tiling, strengthen B component content.

The tackiness agent of sticking cement spare, requiring increases viscosity, makes cement preform bonding firmly, so suitably increase clarified oil, reduces oxidized bitumen and wilkinite, because preform does not require very fast curing, so the most No. 120 general solvent oils of volatility that adopt of solvent.

Example 1, to grow * wide * thick=two battens of 100 * 12 * 3 millimeters stick together with tackiness agent of the present invention, after this agent of external application on every side is coated with two times approximately after parching in 10 hours, be put in the glass that fills with supersaturated brine and in, from in April, 1993 up to now, in also, take out this batten, two battens still agglutinating are very firm, with hand with sudden force lobe do not open, prove that this two battens bubble reaches more than 4 years at salt solution, this tackiness agent stops the brinish etch fully, and tackiness agent is done above similar test with the B component, with sample above situation is arranged.The superpower multi-purpose adhesive that mutually anticaustic Shijiazhuang City Great Wall tackiness agent is produced, use bond with quadrat method after, be put in the salt solution, after only steeping a whole day, exert oneself slightly with hand, two battens have been opened with regard to lobe, behind epoxy resin coating, fall to the greatest extent substantially less than two months, the outer field glue of two battens.

Example 2: with length * wide * thick=100 * 50 * 20 millimeter cement block, with the cement box of the gluing growth of the present invention * wide * thick=100 * 50 * 50 millimeter, in to be coated with this glue thick be 0.5 millimeter, in put existing 5 years of salt solution, the interior salt solution of box does not ooze out outside the box.

Example 3: with three battens of length * wide * thick=200 * 60 * 10 millimeter and two battens of 60 * 60 * 10 millimeters, with box of the gluing one-tenth of the present invention, this box is coated with this glue outward twice, contains in the basin of filling water, so far the existing time more than 2 years, the water in the basin does not advance in this tub all the time.

Example 4: with mosaic, ceramic tile, cement plate box with the gluing growth of the present invention * wide * thick=500 * 500 * 80 millimeter, in be filled with water 2.5 years and do not seep water.

Example 5: with one of 50 * 1 millimeters cardboard of , with glue of the present invention lower rim on the paper is coated with about 0.5 mm thick, after doing, be coated with this glue up, this paper be attached to the steel pipe below of 100 millimeters of 32 * 3 millimeters long, about 2～3 hours, this pipe is put in the cement box of example 2, still piles saturated brine in the box, so far water breakthrough not in the time pipe more than 2 years, after illustrating that this glue is applied to cardboard and steel pipe, salt solution fails that in the time more than 2 years cardboard and steel pipe are had erosion.

Example 6: glue of the present invention reaches large-area construction roofing and hypogee under-20 ℃ of severe cold in the winter time, and the time more than 4 years does not find that a place has roof leaking local so far.

Suffice to show that more than glue of the present invention not only has the advantages of good caking property energy, and extremely strong anticorrosion and sealing impermeable role is arranged, it will be widely used in:

(1) bonding of iron and steel, cement, timber, glass, ceramic pipe fitting and equipment, anticorrosion and waterproof.

(2) crack of iron and steel, timber, pottery, cement, glass, ceramic, repairing that can both be very fast well can withstand voltage 0.3Mpa, temperature can reach more than 100 ℃, and can be durable in use.

(3) antifouling paste of woodwork, the tung oil that can replace wooden boat to use.Also can make the priming paint of boats and ships.

(4) subsides newly or repairing ceramic tile not only can be decorated but also have concurrently water isolating, or be used for the anti-acid flooring, and the B component of this glue is white transparent adhesive tape, can make glass cement, floor glue, tiling glue etc.

(5) the working water-resisting agent in winter roofing and underground structure.

(6) cream of squeegeeing of rigid roofing.

Clarified oil: at the bottom of the catalytic cracking fractionating tower slurry oil through settling section or settling vessel are settlement separate go out catalyst fines after, the oil of drawing from top is called clarified oil.

Take out surplus solvent oil: make raw material with platformate raffinate or straight-run spirit, make through fractionation and other process for purification, initial boiling point is not less than 60 ℃, and 98% recovered temperature is not higher than 90 ℃, as the extraction solvent of vegetables oil processing.

No. 30 sherwood oils: oils, the mixture of the hydro carbons of lowest molecular weight (mainly being pentane and hexane), achromaticity and clarification, the smell that resembles ether is arranged, water insoluble, be dissolved in most of organic solvents, can dissolve oil ﹠ fat etc., the about 0.63-0.66 of proportion is got through fractionation by natural oil, and boiling spread 30-90 ℃ mainly contains two kinds of No. 30 and No. 60, the former boiling point 30-60 ℃, the latter be 60-90 ℃ main as solvent, molten volatile and catch fire, should be during use in attention.
