Abstract

The invention discloses montmorillonite-enhanced solid acrylate resin and a preparation method thereof. The preparation method comprises the following steps: (1) preparing modified montmorillonite suspension liquid by 2-5 parts of octadecyl dimethylallyl ammonium chloride, 150-250 parts of deionized water, 0.2-2 parts of sodium carbonate, and 6-15 parts of montmorillonite; (2) preparing acrylate mixed liquor by 80-140 parts of ethyl acrylate, 60-90 parts of butyl acrylate, 15-30 parts of acrylonitrile, 1-5 parts of acrylic-2-hydroxy ethyl, 0.001-0.5 parts of 1-dodecanethiol, and 0.2-5 parts of azodiisobutyronitrile; (3) adding 150-250 parts of the deionized water, 0.01-2 parts of polyving akohol, and 0.05-0.5 parts of formaldehyde sodium thiosulfate to the suspension liquid in the step (1), and adding the mixed liquor in the step (2), reacting to obtain a mixture, filtering, washing, and drying to obtain a product. The solid acrylate resin has good strength and barrier property.

Description

technical field [0001] The invention relates to a method for preparing a modified montmorillonite reinforced solid acrylate resin. The solid acrylate resin is widely used in coatings, and can be applied to various purposes such as various plastic coatings, metal coatings, printing inks, and the like. Background technique [0002] Montmorillonite, also known as jiaolingite and microcrystalline kaolinite, is a natural mineral of silicate. [0003] According to the dispersion state of silicate sheets in the polymer matrix, polymer / montmorillonite nanocomposites can be divided into two categories: [0004] The first is the intercalated nanocomposite. For the intercalated nanocomposite, the polymer enters between the silicate sheets, which increases the distance between the sheets, resulting in a significant increase in the interaction area. The silicate sheets are in the Keep order at short range, disorder at long range; [0005] The second is the exfoliated nanocomposite. In...
