Abstract
The invention relates to a preparation method of hot melt glue. The preparation method comprises the following steps: (1) adding 10kg-20kg of animal gelatin into 25kg-40kg of water, and stirring at the speed of 220-350r/min for dissolving the gelatin to obtain a solution; (2) adding 8kg-15kg of dimethicone oil, 6kg-12kg of rosin, 0.5kg-2kg of tributyltin chloride and 0.2kg-1.5kg of attapulgite into the solution, stirring to be uniform, adding 35kg-50kg of EVA (Ethylene Vinyl Acetate) resin, heating while stirring until the EVA resin is completely dissolved, after the EVA resin is completely dissolved, and continuously stirring for 10-30 minutes. The preparation method is simple, a volatile solvent is not used, and the hot melt glue is safe and nontoxic.
Description
Technical field
The invention belongs to chemical field, be specifically related to a kind of making method of thermally melting glue.
Background technology
Glue be exactly can bonding two objects material.Glue is not self-existent, and it must be coated in competence exertion bonding effect between two objects.Chemical composition in glue, in aqueous environments.Polymer body in glue (vinyl acetate between to for plastic in white glue is a kind of of petroleum derivative) is all rounded particle, and the radius of general particle is between 0.5～5 μ m.Object bonding, realizes by the pulling force between the polymer body in glue.After printing, binding process technology is after particularly reforming and opening up to the outside world mid-term at the beginning of the eighties in last century, develops very rapidly, no matter is all with in the past to differ widely in technique or in each side such as equipment and materialss.Particularly in the last few years, used this bindery of hot melt adhesive bonding books more and more.Annual by this nearly 3,000,000,000 of quantity of hot melt adhesive bonding books, nearly 8000 tons of hot melt adhesive amount used.This technique has become the main method of bonding book, and the trend also making further progress from now on.
But in hot melt adhesive production process, tend to use volatile solvent now, the producer or user's health are worked the mischief.
Summary of the invention
The making method that the object of this invention is to provide a kind of thermally melting glue, is not used volatile solvent, safety and environmental protection in production and application process in the course of processing.
The present invention is achieved through the following technical solutions:
A making method for thermally melting glue, comprises the following steps: (1), get animal gelatin 10-20kg and add in 25-40kg water, under agitation make gelatin dissolve, stirring velocity is 220-350r/min; (2), in above-mentioned solution, add dimethyl silicone oil 8-15kg, rosin 6-12kg, tributyltin chloride 0.5-2kg, attapulgite 0.2-1.5kg, stir, then add EVA resin 35-50kg, under stirring, heat, dissolve completely to EVA resin, dissolved rear continuation and stirred 10-30min.
Beneficial effect of the present invention: glue production method provided by the invention is simple, in making processes, use gelatin and EVA mixed with resin, compare with simple EVA plastics, the viscosity of glue has improved 25%, use attapulgite to carry out modification to glue, increased glue setting time, improved glue time of drying, make glue shortening time of drying in use, can improve the speed of bonding.Glue production method is simple, does not use volatile solvent, safety non-toxic.
