Novel acrylic flame-retardant board manufacturing process

Abstract

The invention discloses a novel acrylic flame-retardant board manufacturing process. The novel acrylic flame-retardant board manufacturing process comprises a flame retardant liquid preparation chamber and a hot press molding chamber, wherein the flame retardant liquid preparation chamber is composed of an inner tank and an outer tank, the outer tank coats the outer side of the inner tank, and anelectric motor is mounted at the top end of the flame retardant liquid preparation chamber. One side of a bearing machine frame is fixed to a material carrying platform through a bracket, and one endof a liquid pump is connected into the flame retardant liquid preparation chamber through a liquid pumping pipe in a sealing mode, a liquid injecting bin is located on one side of the flame retardantliquid preparation chamber, support legs are installed at four corners of the bottom of the liquid injecting bin, a board material body is disposed at a corresponding position below a liquid injectingnozzle, a notch is formed in the surface of the board material body, and a clamping groove is formed in the board material body. According to the novel acrylic flame-retardant board manufacturing process, specially formulated flame retardant is added into monomer methyl methacrylate to be heated and pre-polymerized, liquid is prepared, then the liquid is injected into the clamping groove inside the board material body, and pressing and molding of the board material are achieved by a hot pressing process.

Description

technical field [0001] The invention relates to the technical field of flame retardant board manufacturing, in particular to a novel acrylic flame retardant board manufacturing process. Background technique [0002] Acrylic, also known as PMMA or plexiglass, has a chemical name of polymethyl methacrylate. It is an important plastic polymer material developed earlier. It has good transparency, chemical stability and weather resistance, easy to dye, easy to process, and beautiful appearance. It is widely used in the construction industry. Plexiglass products can generally be divided into cast sheets, extruded sheets and molding compounds. Acrylic products include acrylic boards, acrylic plastic pellets, acrylic light boxes, signboards, acrylic bathtubs, acrylic artificial marble, acrylic resins, acrylic (latex) paints, acrylic adhesives and other products, with a wide variety. Acrylic products that people often see are acrylic products that are assembled from raw materials s...
