Embodiment 1

[0019] (1) Separation of the nacre: Soak the pearl shells in 3% NaOH solution for 4 days at room temperature. After the horny layer, prismatic layer and nacre of the pearl shells are completely separated, wash the nacre with clean water and dry them;

[0020] (2) Preparation of nacre granules: crush the nacre into particles with a diameter of 1-1.5 mm, then polish and separate them with corn cobs;

[0021] (3) Make pearl glitter plexiglass board:

[0022] A. Preparation of prepolymer: Measure 90mL of MMA (methyl methacrylate), pour it into a 250mL conical flask, add 0.3g of BPO (benzoyl peroxide), stir and dissolve; put the stopper on the conical flask and place it in a constant temperature water bath at 80°C , shake regularly; when the viscosity of the polymerization system is close to that of glycerin, immediately remove the Erlenmeyer flask, cool to room temperature, pour the pearl layer particles in step (2) into the freshly prepared prepolymer, and stir evenly;

Abstract

The invention relates to a manufacturing method of a pearl flash organic glass plate, and belongs to the technical field of organic glass production. The method comprises the following steps of: soaking pearl shells in a NaOH solution at ordinary temperature, washing the pearl layer after completely separating of a horny layer, a prismatic layer and the pearl layer of each pearl shell, drying the pearl layers, and stamping the pearl layers into particles; utilizing a corn cob to polish, pouring the particles of the pearl layers into the prepared prepolymer, uniformly stirring the particles of the pearl layers, pouring into a mould, sealing the mould, putting the particles into a thermostat so as to polymerize, and demoulding the particles so as to obtain the product. A pearl flash organic glass plate is poured by the particles of the pearl layers, the particles of the pearl layers have nacreous luster, the organic glass plate has brilliant rays under illumination, compared with other chemical materials, the color is natural and intensive, and cheerful enjoyment is provided for the people in vision; a raw material is extracted from the waste pearl shells, the source is wide, the price is low, the manufacture is simple and convenient, and the raw material belongs to a green environment-friendly material.

Description

technical field [0001] The invention relates to a method for making a pearl glitter organic glass plate, belonging to the technical field of organic glass production. Background technique [0002] There are currently four types of plexiglass: colorless, colored, pearlescent, and embossed plexiglass. Among them, pearlescent plexiglass is cast by adding pearlescent powder or fluorescent powder to ordinary plexiglass, which has a unique artistic effect. However, pearlescent pigments are expensive, and the treatment will cost a lot, and pearlescent pigments are non-renewable chemical raw material resources, which have a certain impact on China's sustainable development. [0003] Pearl flash plexiglass board is made of nacre particles, which have pearly luster, and can emit the unique light of pearls and natural bright iridescence under the light. Compared with other chemical materials, the color is more natural and richer, giving people A visual delight. And its raw material ...
