Problems solved by technology

Acrylic adhesive is one of the most used types of glue, which has played a major role in national economic construction, national defense construction and people's daily life, and has become one of the most reliable types of glue. The wide use of adhesives and the pursuit of higher quality products are the needs of production and development. Traditionally produced adhesives for rafting boats are not strong in weather resistance, water resistance, adhesion and medium resistance, resulting in serious degumming. Affect the normal work and life of the drifting boat

Description

technical field [0001] The invention relates to an adhesive, in particular to a water-resistant high-viscosity adhesive for a drifting boat. Background technique [0002] Rafting, originally a primitive way of wading, became a real outdoor sport after World War II. Rafting originally originated from the kayaks of the Eskimos and the bamboo rafts of China, but at that time they were all to meet the needs of people's life and survival. Rafting became a real outdoor sport, which began to develop after World War II. Some people who like outdoor activities tried to use decommissioned inflatable rubber boats as rafting tools, and gradually evolved into today's water rafting. In current rafting sports, most of the carriers are rafting boats, which are made of inflatable polymer materials. In the process of preparing rafting boats, adhesives are needed to bond parts. The quality closely affects the quality and life of the drifting boat. [0003] Acrylic adhesives have a wide rang...
