Compared with the prior art, the invention has favourable weatherability and environment protection, can be reused, is favourable for protecting environment and conforms to the current material developing tendency.

Description

technical field [0001] The invention relates to a sanitary product, in particular to a completely recyclable all-thermoplastic sanitary product and a preparation method thereof. Background technique [0002] The current bathroom products are mainly made of ceramics, metals and fiberglass. Ceramics come from nature, and waste sanitary products have less impact on the environment, while metal waste sanitary products can also be recycled, so ceramic and metal sanitary products have less impact on the environment. The manufacturing process of FRP bathroom products is simple and the manufacturing cost is low, so the market share is increasing. However, while the bathroom products made of glass fiber reinforced plastics bring competitive prices, they also bring huge environmental problems. Since the skeleton material of FRP bathroom products is glass fiber-reinforced thermosetting resin such as unsaturated resin, such materials cannot be melted and processed after cross-linking ...
