Abstract

The invention discloses a preparation method of a PMMA / ABS composite material for a bathtub. The preparation method comprises the following steps: putting PMMA resin, ABS resin and MBS resin into a dryer for drying; putting the dried PMMA resin, ABS resin and MBS resin into a high mixing machine; adding a compatilizer, a filler, a lubricant, an antioxidant and a stabilizer into the high mixing machine after the resins are mixed to obtain a mixture; adding the mixture into a co-rotating twin-screw extruder, feeding glass fibers from a third area, melting and extruding, cooling by passing through cold water and slicing to obtain the PMMA / ABS composite material. According to the method, the PMMA is modified by using the ABS resin, the MBS resin and the glass fibers, so that the prepared bathtub has the advantages of excellent high temperature resistance and wear resistance, good impact resistance, no scratches, excellent anti-aging performance and capabilities of greatly improving overallperformance and prolonging service life.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a method for preparing PMMA / ABS composite materials for bathtubs. Background technique [0002] A bathtub is a plumbing fixture used for bathing or showering, usually in a domestic bathroom. [0003] Older bathtubs are usually made of rust-resistant treated steel or iron. [0004] Most of the existing bathtubs are made of acrylic materials. The main reason is that the bathtubs made of acrylic materials have rich shapes, light weight, good surface finish, and the price is lower than traditional steel or iron bathtubs. Easy to clean. [0005] However, most of the existing preparation methods are made of a single acrylic material, and the bathtubs made of it are not resistant to high temperatures, have poor wear resistance, and are particularly prone to aging. Contents of the invention [0006] In view of this, the invention provides a method for preparing a PMMA / AB...
