Problems solved by technology
c. After the current PVC adhesive is dried and cured, due to its poor adhesion, there is no covering and recoating performance. Therefore, when the adhesive coating on the crown cover is too thin or the coating is uneven, it cannot be recoated. , would produce a substandard crown cap
d. Due to the confidentiality of the technology of the manufacturers, there is no company that can produce and supply anti-rust inner coating and adhesive together, which affects the manufacture of crown caps

Abstract
The invention discloses an adhesive, an adhesive-based crown cap and a preparation method of the crown cap. The adhesive contains epoxy resin, phenolic aldehyde, polyethylene, diacetone alcohol, a solvent, isophorone, a defoaming agent, a flatting agent and a catalyst. The adhesive-based crown cap is composed of a cap body, the adhesive and a washer, wherein the cap body is prepared from chromium-plated iron or tin-plated iron; the adhesive is coated on the inside of the cap body and has corrosion resistance and binding property; and the washer is a polyethylene washer and sticks to the inside of the cap body through the adhesive. By adopting the mode, the technological process of the crown cap can be simplified, the damage of polyvinyl chloride can be overcome and the adhesive has both a bonding function and an antirust function.
Description
technical field [0001] The invention relates to the field of adhesives, in particular to an adhesive, an adhesive-based crown cap and a manufacturing method for the crown cap. Background technique [0002] The crown cap is mainly used for sealing glass bottled beer or soda. In order to make a good seal between the bottle mouth and the crown cap and prevent liquid leakage in the bottle, a soft gasket is usually installed inside the crown cap. The installation method is mainly Use adhesives for bonding. [0003] The material of the crown cover in the prior art is mainly tin-plated iron or chrome-plated iron. The manufacturing process is as follows: firstly, a primer is applied on the back of the sheet, and after curing at 200°C / 15 minutes, it is cooled to room temperature, and then a layer of adhesive is applied. As the gasket is mainly polyvinylchloride (PVC) gasket at present, the adhesive is PVC adhesive. After the adhesive is printed, it is cured at 180°C / 15 minutes. Fin...
