The production method is suitable for continuous operation. The hot-melt adhesive has the advantages of no solvent, no pollution, wide adhesive surface, fast curing, no need of drying, and convenient use, etc., and the product also has the characteristics of easy storage and transportation.
Description
Technical field
Product of the present invention belongs to chemical field, particularly relates to a kind of preparation method binding books and periodicals hot melt adhesive.
Background technology
By being divided into open hour and set time, hot melt adhesive ordered by low speed glue to the hot melt adhesive that bookbinding books and periodicals use, hot melt adhesive ordered by middling speed glue, hot melt adhesive ordered by high speed glue; Can be divided into limit glue and gum by purposes, limit glue is used for seal face, and compare gum soft, color is less demanding, and tack requirements is high; Gum to color require slightly high, hardness requirement is larger, its outward appearance is generally cylindrical particles, rounded grain or bulk, and the partially yellow viscosity of appearance color is stronger.In recent years, the development of bookbinding books and periodicals hot melt adhesive is rapid, the bindery of hot melt adhesive bonding books is used to get more and more, this technique has become the main method of bonding book, and also have the trend expanded further in use range from now on, the demand in market facilitates the fast development of bookbinding books and periodicals hot melt adhesive.The development course of the matrix material of books and periodicals is by using flour paste-synthetic resin glue Vinyl Acetate Copolymer-polyvinyl alcohol-hot melt adhesive, especially the appearance of hot melt adhesive substantially increases the speed of the bookbinding processing of books and periodicals, shorten the cycle of publishing books, adapted to publish and social demand.The present invention is a kind of hot melt adhesive of binding books and periodicals and using, this product is that one does not need solvent, the solid fusible polymer of moisture-free 100%, it is solid at normal temperatures, heating and melting becomes can flow to certain temperature, and have the liquid of certain viscosity, in light brown or white after melting, its composition has by basic resin, tackifier, the composition such as viscosity modifier and oxidation inhibitor, basic resin is with the resin of ethene and vinyl acetate between to for plastic copolymerization at high temperature under high pressure, the ratio that this resin uses and quality determine the fundamental property of hot melt adhesive, as the viscosifying power of glue, melt temperature, the effect of tackifier can improve the mobility of colloid and the wettability to adherend, improves adhesive property, reaches required cohesive strength, the effect of viscosity modifier is the mobility, the adjustment setting rate that increase colloid, to reach the firmly object that bonds fast, the effect of oxidation inhibitor is the premature aging in order to prevent hot melt adhesive, because colloid is temperature drift meeting oxygenolysis when melting, add oxidation inhibitor can ensure under the high temperature conditions, adhesive property does not change, and also can add the antiheat agent of cold-resistance agent or applicable tropical temperature in right amount.The bookbinding books and periodicals hot melt adhesive mixing rear production by a certain percentage with above-mentioned raw materials have not containing solvent, pollution-free, bonding wide, solidification rapidly, without the need to the advantage such as dry, easy to use, production method is applicable to continuous operations, and product is easy to store and transport.
Summary of the invention:
The invention provides a kind of preparation method binding books and periodicals hot melt adhesive, produce this tackiness agent with ethene and vinyl acetate resin, petroleum resin, Gum Rosin, polyethylene wax, pentaerythritol ester, barium stearate, antiheat agent R39 is raw material, with pulverizer, blending machine, Banbury mixer, high pressure homogenizer, coagulating pan, crusher is equipment, by the pulverizing of all preparing burden, blending, banburying, homogeneous, solidify, obtained finished product after broken, the raw material weight proportioning that the present invention uses is: ethene and vinyl acetate resin 68%-70%, petroleum resin 5%-7%, Gum Rosin 5%, polyethylene wax 6%, pentaerythritol ester 4%, barium stearate 7%, antiheat agent R39 3%.
The present invention can be achieved through the following technical solutions:
Bind a preparation method for books and periodicals hot melt adhesive, it is characterized in that being made up of following steps:
(1) ethene of formula ratio and vinyl acetate resin, petroleum resin, Gum Rosin, polyethylene wax, pentaerythritol ester, barium stearate, antiheat agent R39 being sent into pulverizing in pulverizer is powder, then sends into blending machine even blend.
(2) all materials in blending machine are sent into Banbury mixer, the temperature in Banbury mixer is adjusted to be 120-130 DEG C, banburying is stopped after banburying 1.2-1.4 hour, all materials in Banbury mixer are sent into high pressure homogenizer, carry out extruding under the condition of insulation, impact, decompression expansion triple role carries out homogeneous, the homogeneous time is 0.4-0.6 hour.
(3) all materials in high pressure homogenizer are sent into coagulating pan, at normal temperatures natural coagulation, solidify rear feeding crusher, after being broken for particulate state, obtain the hot melt adhesive of binding books and periodicals use.
Banburying temperature in Banbury mixer described in step (2) is 125 DEG C, and the banburying time is 1.3 hours.
Normal temperature in coagulating pan described in step (3) is 5-30 DEG C.
The invention has the beneficial effects as follows: provide a kind of preparation method binding books and periodicals hot melt adhesive, the method has advantages such as using general-purpose equipment, production technique are simple, low production cost, good product quality; Product have not containing solvent, pollution-free, bonding wide, solidification rapidly, without the need to the advantage such as dry, easy to use.
