Abstract
The invention discloses an adhesive used for a waterproof carton and a preparation method thereof. The adhesive is composed of waterborne polyurethane, cassava starch, light calcium powder, ceramic powder, a cross-linking agent TAIC, mineral oil, isopropyl distearoyl aluminate, 2-methylimidazole, methylbenzotriazole, borax, hydroxypropyl methyl cellulose and water. Waterborne polyurethane and cassava starch are used as main materials. By pre-treating the cassava starch, excellent performance of the cassava starch is improved; water resistance of the adhesive is increased greatly; and the service life of the adhesive is prolonged. Besides, the adhesive is simple in preparation method, low in cost and suitable for large-scale production.
Description
Technical field
The invention belongs to production of adhesive technical field, be specifically related to a kind of water tolerance carton and stick with glue agent and preparation method thereof.
Background technology
At present, the product of printing industry, material is a lot, quality in order to ensure wrapped product, prevent toxic substance, the application of wrapped product inferior, must get hold of the use of tackiness agent, starch adhesive is more and more subject to the favor of carton production firm as environmentally friendly natural adhesive, but at present at carton production industry starch adhesive used, mainly with starch, water, sodium hydroxide, the starting material such as oxygenant are made, shortcoming is that rate of drying is slow, bonding strength is low, poor water resistance and storge quality are unstable etc., thereby limited to a certain extent its application in carton production industry.
Summary of the invention
The object of the present invention is to provide a kind of water tolerance carton to stick with glue agent and preparation method thereof.
The present invention adopts following technical scheme:
Water tolerance carton sticks with glue agent, and the weight part of its constitutive material is: aqueous polyurethane 55-65, tapioca (flour) 20-25, light calcium carbonate powder 35-40, ceramic powder 18-22, linking agent TAIC 0.8-1.0, mineral oil 2.5-3.0, sec.-propyl distearyl acyl-oxygen base Aluminate 4.3-4.8,2-Methylimidazole 8.0-10.0, methyl benzotriazazole 0.4-0.6, borax 14-18, Vltra tears 1.7-2.3 and water 480-550.
Water tolerance carton sticks with glue agent, and the weight part of its constitutive material is: aqueous polyurethane 60, tapioca (flour) 22, light calcium carbonate powder 38, ceramic powder 20, linking agent TAIC 0.9, mineral oil 2.8, sec.-propyl distearyl acyl-oxygen base Aluminate 4.5,2-Methylimidazole 9.0, methyl benzotriazazole 0.5, borax 16, Vltra tears 2.0 and water 510.
Water tolerance carton sticks with glue the preparation method of agent, comprises the following steps:
(1) processing of tapioca (flour): the weight part by constitutive material takes tapioca (flour), add water heating gelatinization to process, then the Sodium Persulfate, 1-2% MALEIC ANHYDRIDE, the 1-2% vinylbenzene that add tapioca (flour) total mass 1.0-3.0%, stirring reaction 20-30min, after cooling, use again ultrasonication 2-3h, take out and get final product;
(2) by the weight part of constitutive material, take each constitutive material, tapioca (flour), aqueous polyurethane and remaining water after first above-mentioned steps (1) being processed mix, and stir, and then add successively other constitutive material, then stirring reaction 2.0-2.5h, obtain.
Beneficial effect of the present invention:
It is major ingredient that the present invention adopts aqueous polyurethane and tapioca (flour), by anticipating tapioca (flour), improved the premium properties of tapioca (flour), in formula, increase mineral oil, greatly improved the water tolerance of product, postpone the work-ing life of tackiness agent, and preparation method of the present invention has been simple, cost is low, is applicable to scale operation.
