Technical Field
The invention belongs to the technical field, and particularly relates to an anti-skid adhesive for stacking and a preparation method thereof.
Background
Along with the normalization of transportation with a clamping plate in the logistics industry and the requirements of production and storage of enterprises, stacking safety is more and more emphasized. The traditional anti-slip agent product is mainly applied to the ground, has high viscosity and strong adhesive force, and is not suitable for stacking of clamping plates. The anti-slip adhesive product for stacking is adhered to the surface of a packaging base material through a glue spreader, so that the friction force between packaging materials is increased, the products are not easy to displace after use, and the height and the stability of stacking can be effectively guaranteed. The stacking anti-skid adhesive needs to have good adhesive force and moderate adhesive force on the surfaces of various base materials, the stability of stacking is improved, the easy separation of the adhesive surfaces of products is ensured, and the base materials cannot be damaged during separation.
The related technology of the existing anti-slip adhesive for stacking is less, the invention discloses a method for preparing anti-slip adhesive by using potato powder in patent CN201710830090.0 and application, and the anti-slip adhesive is formed by heating potato starch and water for gelatinization; the invention discloses a method for preparing an anti-skid adhesive by using mung bean starch CN2017108301176 and an application thereof, wherein the anti-skid adhesive is formed by heating and gelatinizing the mung bean starch and water; the two are suitable for the mutual adhesion between the packing cartons of products, especially the anti-slip adhesion in the stacking process between the cartons without bright surfaces, can ensure the stability of stacking, and are easy to separate. However, the anti-slip adhesive prepared from the anti-slip adhesive and the preparation method thereof has poor adhesion to the surface of a base material and low bonding strength, is not suitable for base materials with smooth surfaces such as PE bags and the like, and greatly limits the application of the anti-slip adhesive for stacking.
Disclosure of Invention
The invention aims to solve the technical problem of providing the anti-slip adhesive for stacking, which is suitable for various base materials such as cartons, PE bags, woven bags and the like, has good film forming property, good film coating adhesive force and moderate adhesive strength, is easy to separate, does not damage the surface of the base material, and can effectively improve the stacking height and stability.
The technical scheme of the invention is as follows:
the anti-slip adhesive for stacking comprises the following components in percentage by mass: 4-6% of barley, 16-20% of sweet potato powder, 3-8% of absolute ethyl alcohol and the balance of water.
The preparation method of the anti-slip adhesive for stacking comprises the following steps: soaking fructus Hordei vulgaris in water for 24-36 hr, filtering to obtain residue, naturally air drying at room temperature, and grinding into powder; adding water and sweet potato powder, stirring, heating to 85-90 deg.C, stirring for 15-30min, cooling to room temperature, filtering to obtain filtrate, adding anhydrous ethanol, and stirring.
The invention has the following beneficial effects:
the sweet potato powder selected by the invention has good viscosity, gel property and shearing resistance, the barley powder has good expansibility, water absorbability and aging resistance, the two are compounded, the amylopectin content is high, water is easy to permeate, and the barley powder is swelled and split at high temperature to form a uniform pasty solution with certain viscosity, so that the adhesive is good in film forming property, high in transparency, suitable in bonding strength after curing, good in substrate adhesive force, large in transverse shearing force of a cured film, excellent in anti-skid property, capable of effectively improving the stacking height and stability, small in longitudinal tension of the cured film, easy to separate, and free of damaging the substrate surface after separation. The absolute ethyl alcohol has good volatility, and can improve the transparency, film-forming property and curing speed of the adhesive.
The preparation method of the adhesive is simple, and the viscosity of the adhesive can be controlled by adjusting the gelatinization temperature and the gelatinization time, so that the adhesive force and the adhesive force of the adhesive are adjusted, and the adhesive is suitable for the surfaces of various base materials.
Detailed Description
The present invention will be described in detail with reference to examples, which are only preferred embodiments of the present invention and are not intended to limit the present invention.
