Problems solved by technology

However, some problems have been encountered when soft PVC is used to make baby inflatable bathtubs: baby inflatable bathtubs need to be in constant contact with hot water, and PVC has poor heat resistance and thermal stability, and the higher the temperature, the lower its chemical stability; The baby inflatable bathtub will move around when used, and will contact and rub against the ground or wall with high hardness, while the wear resistance of PVC is average, and the wear will be serious after a long time of use, shortening its service life

Description

Technical field: [0001] The invention relates to a PVC composite material, in particular to a PVC composite material for a heat-resistant baby bathtub and a preparation method thereof. Background technique: [0002] PVC, or polyvinyl chloride, is a thermoplastic resin with good mechanical properties and dielectric properties. It is divided into soft and hard PVC. Soft products are flexible and tough, and have a wide range of applications. However, some problems have been encountered when soft PVC is used to make baby inflatable bathtubs: baby inflatable bathtubs need to be in constant contact with hot water, and PVC has poor heat resistance and thermal stability, and the higher the temperature, the lower its chemical stability; The baby inflatable bathtub will move around when used, and will contact and rub against the ground or wall with high hardness, while the wear resistance of PVC is average, and the wear will be serious after a long time of use, shortening its service ...
