Abstract

The invention discloses a modification method of an easily-to-grab anti-skid swim ring. The modification method comprises the following steps: mixing graphene oxide and modified molybdenum disulfide,adding deionized water, sealing, carrying out ultrasonic stirring, adding ammonia water to adjust the pH value to be neutral, adding waterborne polyurethane, and uniformly mixing to obtain pretreatedwaterborne polyurethane; adding modified nano calcium carbonate and modified silicon dioxide into the obtained pretreated waterborne polyurethane, heating and magnetically stirring, adding plasticizerglycerol, continuously stirring, standing and degassing to obtain an antiskid wear-resistant coating; and uniformly coating the surface of a swim ring with the obtained antiskid wear-resistant coating by using a coating rod, naturally drying, and carrying out rewetting treatment in a constant-temperature and constant-humidity box to obtain the antiskid wear-resistant swim ring.

Description

technical field [0001] The invention belongs to the field of swimming rings, and in particular relates to a modification method of an easy-grip anti-slip swimming ring. Background technique [0002] Swimming rings are similar to life buoys and are used in water. Blow the air, the swimming ring will have buoyancy, the inside is full of air, put it on the waist, and then jump into the water, the swimming ring can be used to assist learning to swim. The swimming ring is suitable for the majority of children and the younger generation. The swimming ring has the characteristics of safety, hygiene and novelty. It is the best product for baby's fitness and games. It is cute in shape, fashionable in style, bright in color, easy to carry, and never gets tired of playing. It is the latest playmate for babies. [0003] Swimming ring has the advantages of cheap price, beautiful pattern, and is deeply loved by children and fashionable young men and women. It is inflated and easy to car...
