background technology:
The application of carton, Corrugated Box is more and more extensive.First the quality of Corrugated Box depends on the quality of corrugated cardboard, and the corrugated cardboard of high-quality is the prerequisite of making qualified carton.Quality of corrugated is relevant with the state of the art of temperature, web tension, tackiness agent and operator in making processes.
At present, in Corrugated Box production line, the tackiness agent of corrugated cardboard is mainly used Starch Adhesive, body paper is to consist of multiple fiber molecule, and starch adhesive is penetrated into fiber and forms the glue nail of root top shape from the surperficial pore of paper, between lining paper and stupefied peak, by glue, is followed closely effectively and is bonded together.And Starch Adhesive prepared by the raw ripe adhesive process of tradition can not adapt to the demand of high-speed production far away, high-strength corrugated board papery is better, tightness is high, and top sizing pore is blocked, and general glue perviousness is poor, easily occur false sticky, bubble, the quality problems such as come unstuck, consume starch too much, thereby cause that productivity is low, production cost is high, unstable product quality.
summary of the invention:
The deficiency existing in order to solve prior art, the invention provides a kind of glue for Corrugated Box high-speed production, and bond properties is good, paperboard bonding quality is improved, at utmost to adapt to the processing requirement of Corrugated Box high-speed production lines.
For solving the problems of the technologies described above, the present invention takes following technical scheme: a kind of glue for Corrugated Box high-speed production, and the raw material that contains following parts by weight:
175 ~ 225 parts of starch
700 ~ 800 parts, water
4.5 ~ 6.5 parts, caustic soda
3 ~ 4.5 parts of boraxs
4 ~ 6 parts of stablizers
3 ~ 5 parts, siccative
The present invention for the preferred parts by weight of glue Raw of Corrugated Box high-speed production is: 200 parts of starch, 750 parts, water, 5.5 parts, caustic soda, 3.5 parts of boraxs, 5 parts of stablizers, 5 parts, siccative.
Described starch is W-Gum or tapioca (flour).
The consumption situation of described siccative is adjusted according to the variation of weather.
The method of the glue for Corrugated Box high-speed production described in preparation comprises the following steps:
(1) caustic soda is added to the water and is reacted, make caustic soda completely soluble in water;
(2) starch is stirred after 5min, slowly add water-soluble caustic soda to stir and reach finite concentration;
(3) in uniform stirring, add borax, stablizer, siccative, and mix stirring 20min, get product.
Glue for Corrugated Box high-speed production prepared by the present invention, to add starch additive as auxiliary material, make up the defect of rubber making method, not only improved paperboard bonding quality, improved cardboard soft, bending, be unable to lift the problems such as high speed, make the Corrugated Box high-speed production lines speed of a motor vehicle bring up to 50%, and technical process is simple, safe and reliable, low production cost, thus be adapted to the processing requirement of Corrugated Box high-speed production lines.
