Problems solved by technology

However, the coating mainly uses talcum powder, mica powder, calcium carbonate, kaolin, barium sulfate, and montmorillonite to achieve sound insulation effects. Most of these materials are irritating to a certain extent, have an impact on human health, and are not environmentally friendly.

Abstract

The invention provides a sound-insulation styrene-acrylic emulsion based composite coating preparation method. The method includes steps: (1) soaking palm leaves into water, taking out, soaking into a composite solution, taking out, flushing, drying in air, soaking in a softening agent, taking out, drying, and opening to obtain crude fibers of the palm leaves; (2) adding the crude fibers of the palm leaves into a sodium hydroxide solution, heating, taking out, centrifugally dealkalizing, soaking in water, neutralizing, taking out, washing with water, and drying to obtain alkalized crude fibers of the palm leaves; (3) grinding the alkalized crude fibers of the palm leaves in a particle grinder, transferring to a microjet nano homogenizer for treatment, and drying to obtain fibers of the palm leaves; (4) adding styrene-acrylic emulsion into a stir reactor, starting stirring, adding a coupling agent, well mixing, adding fillers, a flame retardant and the fibers of the palm leaves, well mixing, adding water, a coalescing agent and a thickening agent, well mixing, grinding and dispersing. A sound-insulation styrene-acrylic emulsion based composite coating prepared according to the method has an excellent sound insulation performance and is harmless to human health and environment friendly.

Description

Technical field: [0001] The invention relates to a styrene-acrylic paint, in particular to a preparation method of a sound-insulating styrene-acrylic emulsion-based composite paint. Background technique: [0002] Styrene-acrylic emulsion is the abbreviation of styrene, acrylate, acrylic acid ternary copolymerization emulsion. Adhesives, etc., especially in recent years, it has been used as water-based anti-rust latex paint. It has the advantages of non-toxic, odorless, non-flammable, less pollution, weather aging resistance, light aging resistance, chemical corrosion resistance, and adjustable gloss. Anti-rust coatings have the disadvantages of being flammable, explosive, toxic, and seriously polluting the environment. However, ordinary styrene-acrylic coatings do not have sound insulation function and cannot be used in residential quarters, tunnels, road noise barriers, villas, high-end residences, hotels, schools, gymnasiums, concert halls, opera houses, factories and oth...
