BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Figure 1 This is a scene diagram of an example of application of the present invention. DETAILED DESCRIPTION

[0036] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0037] After the surface coating glue on the market is applied on the surface of the product, the coating has strong stickiness and can only be used for pasting. Some surface coating glues are applied on the surface of the product and dry, but have no stickiness at all, and can only be used to protect the surface of the product. The use is relatively single and cannot meet the requirements of mild sticky adsorption performance. The surface coating glue with continuous sticky effect can be adsorbed on the surface of plastic products after being applied on the surface of the product and dried, and can be removed. In response to this, the inventor proposed a surface-drying surface coating glue that can automatically adsorb plastic and a manufacturing process to solve the above problems.

[0038] The present invention provides the following preferred embodiments

[0039] The present embodiment provides a surface coating adhesive that can automatically absorb plastic after being dried on the surface. The coating adhesive includes a type A resin adhesive and a type B resin adhesive that is mixed with the type A resin adhesive by low-temperature thermal reaction. The type A resin adhesive ingredients mainly include beryllium oxide powder, nitric acid, water, hydrogenated rosin and additives. The proportions of beryllium oxide powder, nitric acid, water, hydrogenated rosin and additives are 50%, 15%, 3% and 2%. When preparing the type A resin adhesive, the beryllium oxide powder, nitric acid, water, hydrogenated rosin and additives with good proportions are first poured into a container in sequence, so that the beryllium oxide powder, nitric acid and water react to generate beryllium nitrate, which reacts with the hydrogenated rosin as an organic reaction catalyst, and the reaction is accelerated by the additives. After being melted at high temperature, the beryllium oxide powder, nitric acid, water, hydrogenated rosin and additives are cooled to form a liquid, so as to obtain the type A resin adhesive.

[0040] The ingredients of Class B resin glue mainly include borax, potato starch, water and additives. The ratios of borax, potato starch, water and additives are 50%, 10%, 38% and 2%. The main component is borax, and borax is easily soluble in water. After the borax reacts with potato starch and water, the produced glue has strong toughness and elasticity, anti-corrosion effect, and can inhibit the growth of bacteria and mold, ensuring that the glue can be used for a long time, increasing the service life of the glue, and accelerating the reaction through additives. The reaction is left to stand for a period of time to produce Class B resin glue.

[0041] It should be noted that, in this embodiment, the auxiliary agent may be a catalyst or a promoter.

[0042] In summary: the manufacturing process steps of the surface-drying and automatically adsorbable plastic surface coating adhesive are as follows;

[0043] S1. Disperse the prepared Class A resin glue in advance and stir it evenly. That is, stir the prepared Class A resin glue evenly first to prevent the Class A resin glue from agglomerating, which is convenient for subsequent processing;

[0044] S2, put the stirred Class A resin glue into a container, seal it with a plastic film, heat it to 80°C, and keep it warm for 1.5 hours;

[0045] S3, taking out the liquid type A resin glue formed in step S2 into another container, adding the type B resin glue according to proportion and stirring for 45 minutes;

[0046] S4. After stirring, seal with plastic film and heat to 50°C for 2.5 hours to obtain surface coating adhesive.

[0047] A lightly sticky surface coating adhesive is prepared by hot-melting a mixture of type A resin adhesive and type B resin adhesive. The surface coating adhesive is applied to the corresponding product and fixed to the product after drying, so that the product can be lightly adhered to the surface of plastic items and can be easily removed without losing its stickiness. Beryllium oxide powder, nitric acid, water and hydrogenated rosin are added to type A resin adhesive. Beryllium oxide powder is added to nitric acid to generate beryllium nitrate, which acts as an organic reaction catalyst to react with hydrogenated rosin, so that the produced glue has initial viscosity, compatibility, adhesion, aging resistance and antioxidant properties. Good performance, low brittleness and high thermal stability; Borax, potato starch and water are added to Class B resin glue to react, so that the produced glue has strong toughness and elasticity, anti-corrosion effect, and can inhibit the growth of bacteria and mold, ensuring that the glue can be used for a long time, thereby increasing the service life of the glue; by neutralizing Class A resin glue and Class B resin glue, the viscosity of the glue is reduced without eliminating the viscosity of the glue, making the glue slightly sticky, and at the same time making the glue have strong toughness, antioxidant, aging resistance, corrosion resistance and fire resistance after coating.

[0048] The surface coating glue prepared above is used as a surface coating for toy dartboards, cultural supplies, sporting goods, etc. The surface coating glue is taken out for coating, and then dried at 60°C to form an adsorption layer; for example, Figure 1 As shown, the prepared surface coating glue is coated on the bracket panel, and after being dried at 60°C, a slightly sticky adsorption layer is formed on the surface of the bracket panel. When the user throws toys or needleless darts or stationery or plastic products or silicone rubber products onto the bracket panel, the adsorption layer sticks and adsorbs the toys or needleless darts or stationery or plastic products or silicone rubber products onto the bracket panel. At the same time, the user can easily remove the toys or needleless darts or stationery or plastic products or silicone rubber products stuck on the bracket panel. Compared with other glues, the surface coating glue has low viscosity and can adhere to products with relatively small volume or weight; in particular, toy products, this can improve the fun and safety of the toys. When the surface coating glue is used in toy products, especially silicone rubber toy products, or shatter-resistant plastic toy products, when the toy is thrown onto a wall or other flat surface, the toy can be adsorbed on the wall or other flat surface, thereby improving the fun and safety of the toy.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
