Abstract

The technical proposal of the invention discloses a composite bathtub and a manufacture process thereof, and relates to the manufacture of the bathtub. The composite bathtub mainly comprises a flexible material shell, a shell, and a foamed polyurethane flexible material layer and a fiber bonding layer which are positioned between the flexible material shell and the shell as filling layers, wherein the flexible material shell is bonded to the foamed polyurethane flexible material layer and combined with the shell into a whole through the foamed polyurethane flexible material layer and the fiber bonding layer. The manufacture process for the bathtub is mainly characterized in that a mould for an inner shell of the bathtub is a mould for manufacturing the flexible material shell, and is an upper mould and a lower mould capable of absorbing the material of the flexible material shell; and in the flow of forming the bathtub, a polyurethane liquid is injected into an outer shell of the bathtub firstly, and then the upper mould absorbing flexible plates of the flexible material shell is placed into the outer shell of the bathtub, and the polyurethane liquid is foamed to become the foamed polyurethane flexible material layer. The product manufactured by the invention is flexible and full of elasticity, and improves the bathing comfort and using safety.

Description

technical field

[0001] The technical solution of the invention relates to the technical field of sanitary ware, in particular to a bathtub. Background technique

[0002] In my country's patent documents, there is an application number of 200510041549.6, which is called a patent document for a composite bathtub and its manufacturing process. The bathtub inner shell and bathtub outer shell are made of acrylic (PMMA / FRP) sheet, and the bathtub body is thick, which enhances the strength of the bathtub, but there are problems caused by the excessive hardness and smoothness of the surface of the bathtub bottom. Safety is poor during use, and comfort is unsatisfactory defective during bathing.

[0003] In my country, people are used to calling the artificial leather produced with PVC resin as PVC artificial leather; the artificial leather produced with PU resin as raw material is called PU artificial leather; the artificial leather produced with PU resin and non-woven fabric as raw ...
