Removable traceless glue and manufacturing process thereof

Abstract

The invention relates to removable traceless glue and a manufacturing process thereof, which belong to the technical field of sticky glue. The removable traceless glue comprises a sticking layer and a base material layer, wherein the sticking layer is prepared from polyurethane synthetic resin which comprises the following raw materials in parts by weight: polyether polyol resin, acrylic resin, unsaturated polyester resin, tung oil, amino resin, rosin resin, epoxy resin, chemigum, phenolic resin, xylene, calcined kaolin, zinc oxide, an antioxidant, a stagnation agent, an anti-ultraviolet agent, a curing agent, a light stabilizer, a photoinitiator, organophosphorus, a vulcanizing agent, an anti-aging agent and a tackifier. According to the matching of the removable traceless glue, the whole preparation of the raw materials of the polyether polyol resin is environmental friendly and the raw materials are low in price, and no harm to human bodies is generated, and secondary pollution to the environment cannot be caused, in addition, the removable traceless glue can be recycled through reproduction, and any residual glue cannot be left after long-term sticking and use, and the removable traceless glue can be repeatedly torn and used, and the surface of the removable traceless glue can be directly cleaned with tap water or a detergent when dust is adhered to the surface.

Description

technical field [0001] The invention relates to the technical field of viscous glue, in particular to a removable traceless glue and a manufacturing process thereof. Background technique [0002] With the continuous improvement of people's living standards, the use of various digital products continues to increase, especially mobile phones, tablet computers, handheld game consoles, etc. When people play handheld game consoles, they can stick the handheld game consoles on tables, chairs or For pasting places such as the head of the bed, the existing pastes use suction cups or superglue, etc. The suction cups have strong adsorption force and can be removed as needed, but the smoothness of the pasting surface must be high, otherwise it cannot be adsorbed; the superglue takes a long time after pasting If it is removed by force, it will inevitably leave sticky marks, including sticky marks on the pasted object and the wall. In severe cases, it will even damage the wall or the pas...

Problems solved by technology

[0004] The first type of SEBS (TPR) artificial rubber, because it does not have long-term effective surface viscosity, so it must be dissolved into a liquid at high temperature during the preparation process before adding white oil and white oil tackifier, but white oil and white oil increase If the adhesive is added too much, it will be difficult to cure, and the surface will leak oil when pasting, so that the effect of seamless pasting cannot be achieved. Therefore, the sticking force of SEBS (TPR) artificial rubber system stickers has great limitations, and the aging resistance is not enough. , the original surface viscosity will be lost in a short period of time after ultraviolet light irradiation, so the scope of use is limited

[0005] The second type of hot-melt pressure-sensitive adhesive system stickers, the resin system is semi-solid or solid, containing synthetic rubber, pressure-sensitive resin and rubber oil, mixed and heated into a molten state before coating, because the molten state is thicker and Severe wire drawing, yellowish colloid, not transparent enough, not easy to coat, and the coating thickness error is large, surface flatness is not good, aging resistance, temperature resistance is insufficient, the most important thing is that the hot melt pressure sensitive adhesive system sticks for a long time There will be glue remaining on the surface of the adhered object, so the effect of truly seamless paste cannot be achieved

[0006] In addition, the invention patent with the patent publication number "CN103937197A" discloses a polyurethane synthetic resin for preparing non-marking adhesive tape and the non-marking adhesive tape prepared by using it. The effect is poor, and its weather resistance and anti-aging performance are poor

The overall preparation method of the invention is simple, and the traditional curing method cannot effectively control the stickiness of the product, and this preparation method cannot control the product efficiency, but will increase the defective rate of the product
