Problems solved by technology

It has the following defects: 1. The degree of environmental protection does not meet the standards of the food and daily chemical industry
2. The adhesion to plastic PP with low polarity is small, and the adhesion strength is not enough
3. There will be wire drawing during operation. These glue wires will not only make it difficult to clean the outside of the parts, but also cause the entire working environment to be untidy
4. Unable to carry out automatic assembly line operation, low production efficiency

Abstract

The invention discloses a hot melt adhesive for food and daily chemical product bottle caps. The hot melt adhesive is prepared from the following components in parts by weight: 40-60 parts of amorphous poly alpha olefin, 20-40 parts of hydrogenated petroleum resin and 0.5-1.5 parts of an anti-aging agent. The invention further discloses a preparation method of the hot melt adhesive. By adopting the technical scheme, the hot melt adhesive for food and daily chemical product bottle caps is good in affinity to non-polar plastic and metal, high in adhesive force and good in high-temperature resistance and low-temperature resistance, meets the requirement for environment-friendliness of the food and daily chemical product industry, is applicable to automatic assembly line operation, is smooth in operation process and free of wire drawing phenomenon, the production efficiency is greatly improved, and the tidiness of processed parts and operation environments can be well maintained.

Description

technical field [0001] The invention relates to hot-melt adhesives, in particular to hot-melt adhesives for food and daily chemical bottle caps and a preparation method thereof. Background technique [0002] Early food and daily chemical bottle caps (such as beverage bottle caps, wine bottle caps, sprayer bottle caps, cosmetic box caps, etc.) are bonded between alumina and PP plastic sheets, and epoxy resin glue is used. It has the following defects: 1. The degree of environmental protection does not reach the standards of the food and daily chemical industry. The raw materials it contains, such as reactive diluents, curing agents, etc., have varying degrees of toxicity and irritation. 2. The adhesion to plastic PP with low polarity is small, and the adhesion strength is not enough. 3. There will be wire drawing during operation. These glue wires will not only make it difficult to clean the outside of the parts, but also cause the entire working environment to be unclean. ...
