Problems solved by technology
[0002] At the present stage, most acrylic bathtubs are manufactured by heating and softening the entire acrylic sheet and fixing it on an automatic molding machine. The molding machine will attach the softened sheet to the surface of the bathtub mold cavity through vacuum adsorption, and then cool and demould to obtain The acrylic layer (surface layer) of the bathtub is sprayed with an adhesive buffer layer, a glass fiber reinforced plastic insulation layer, a structural reinforcement layer and an adhesive buffer layer on the back of the bathtub surface layer to form an inner layer, and finally the production of the bathtub can only be completed after cutting edges, opening holes, and grinding and polishing Preparation, has the disadvantages of cumbersome manufacturing process, poor aesthetics, and poor environmental protection

Embodiment Construction
[0016] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the best embodiments.
[0017] The present invention comprises the following steps:
[0018] a. Slurry pre-polymerization: 1000 kilograms of MMA monomers are put into the reactor, and an appropriate amount of initiator is added while stirring. The initiator used in this embodiment is azobisisobutyronitrile, and the consumption is 14 grams. Heat the temperature of the reactor to 99-101°C and keep it warm for 1 minute to obtain a mixture. When the mixture has a large number of bubbles, cool the reactor to below 36°C to obtain a pre-polymerized slurry. The pre-polymerized slurry prepared in this example is coated with four The cup viscosity is 100±10 seconds. In order to prevent the slurry from continuing to react and solidify, it should be stored in a storage tank for later us...

The invention relates to the field of bathtub production processes, in particular to a production method of an integrated acrylic bathtub. The production method of the integrated acrylic bathtub comprises the following steps of pre-polymerizing a sizing agent, preparing the sizing agent, injecting, polymerizing and curing, cutting and trepanning, and grinding and polishing. Compared with a traditional acrylic bathtub structure, the acrylic bathtub produced by the invention is of a single-layer structure; by utilizing the method provided by the invention, the manufacturing process of the acrylic bathtub can be effectively simplified, and the production efficiency is improved; no functional strengthened coating and reinforced glass fiber is used as a lining material, so that recovery processing can be carried out, and the pollution on the environment is low; and meanwhile, the acrylic bathtub produced by using the method is smooth and flat in surface and attractive in appearance.
