The preparation method of full-service fluid glue
Technical field
The present invention relates to a kind of preparation method of full-service fluid glue.
Background technology
Liquid glue has good viscosity, can be used for the adhesive paper goods, is office and the study article of a high-quality.
But liquid glue commonly used just is used for pasting paper, and the material require of other side is when pasting, more use be 502 glue, hundred glue such as glue.
502 glue are based on ethyl, add tackifier, stablizer, toughner, stopper etc., by the synthetic single-component instantaneous solidification tackiness agent of vanguard technology.
502 glue are a kind of super glue, water white transparency, and good fluidity, volatile, meeting water is polymerizing curable.And 502 glue are single-component, curing speed is fast, easy to use, bonding force is strong, adhesives is extensive, can be used for iron and steel, non-ferrous metal, rubber, leather, plastics, pottery, glass, timber etc., but be used for polyethylene, polypropylene, polytetrafluoroethylproducts products, material surface needs through special processing.Be widely used in electrical equipment, instrument, machinery, electronics, light instrument, medical treatment, the civilian industry by the time of light industry.
But, 502 glue, hundred the organic solvent that contains of glue such as glue is toluene, benzene, acetone, influential to person health, the limitation of use is also more intense.
Summary of the invention
The technical issues that need to address of the present invention just are to overcome the defective of prior art, a kind of preparation method of full-service fluid glue is provided, technology of the present invention is simple, the liquid glue of preparation is a kind of single-component liquid glue, easy to use, have multiduty function, its viscosity is strong, of many uses, main bonding paper, fiber board, fabric, cork, leather, timber, pottery, coloured glaze, card and plastic or other material.The human consumer be as long as buying one bottle just can use in many-side, do not need to paste to glue the glue that a kind of material will adapt with purchase.Its heavy metal detects and meets relevant criterion fully.
For addressing the above problem, the present invention adopts following technical scheme:
The invention provides a kind of preparation method of full-service fluid glue, pressing row weight part proportioning adds raw materials used: under normal temperature condition, in anti-still, add 5 parts of deionized waters, polyvinyl alcohol 10-15 part, be warming up to 90 ℃, add N-BUTYL ACETATE 20-25 part, glycerol 15-20 part, insulation reaction 1 hour after the dissolving fully, being down to normal temperature adds ethanol 8-15 part, polyvinyl acetate 15-20 part again, adds an amount of sanitas and defoamer, static froth breaking again.
Described sanitas is Ka Song and Bu Luo bohr, and described defoamer is silicone oil.Technology of the present invention is simple, only need the proportioning weighing is accurate, temperature to be controlled well, and the reaction times has been controlled well just.In whole process, there is not any waste, pollution-free generation, production keeps clean.
Full-service fluid glue environment-protecting asepsis, burning-point height, the viscosity height of the present invention's preparation; Of many uses, be suitable for daily, the home decoration of the daily life of a family etc., main bonding paper, fiber board, fabric, cork, leather, timber, metal, pottery, coloured glaze, card and plastic or other material.
The liquid glue of the present invention's preparation is a kind of single-component liquid glue, and is easy to use, has multiduty function, and its viscosity is strong, and is of many uses, main bonding paper, fiber board, fabric, cork, leather, timber, pottery, coloured glaze, card and plastic or other material.The human consumer be as long as buying one bottle just can use in many-side, do not need to paste to glue the glue that a kind of material will adapt with purchase.Its heavy metal detects and meets relevant criterion fully.
It is main raw material that the present invention adopts polyvinyl acetate, is added with reactions such as PVA, ethanol, glycerol, N-BUTYL ACETATE and generates.Compare with the general-purpose glue on the market:
1, full-service fluid glue of the present invention is environment protection type multifunctional glue, and nontoxic, burning-point is low.
The general-purpose glue that market is used has dense smell, and to the people of life-time service, health has certain influence.And the general-purpose glue burning-point height on the market, when producing, very big danger being arranged, the friction of doughnut during answering cell phone, causes possibly and catches fire.
2, to add glycerol mainly be to improve boiling point in the present invention, makes the formation ternary azeotropic, improves the burning grade, thereby improve burning-point, and when producing, any Mars can not cause and catches fire.
Embodiment
In the following example, sanitas is Ka Song and Bu Luo bohr, and defoamer is silicone oil.
