Problems solved by technology

[0003] However, the current acrylic sheet has general light transmission performance and poor mechanical properties. Therefore, it is necessary to seek a method that can remove impurities such as polymerization inhibitors and moisture, increase the reflectivity of the sheet, reduce the degree of light decay, and thereby improve the light transmittance. It is necessary to make the acrylic sheet with a light transmittance of more than 94% and good mechanical properties

Abstract

The invention discloses a acrylic plate for light guiding and a production method thereof. The acrylic plate for light guiding is prepared from the following raw materials of, in parts by weight, 40-50 parts of methyl methacrylate, 20-30 parts of acrylic resin powder, 2-4 parts of stearyl amine, 6-9 parts of nano organic silicone resin powder, 1-3 parts of 2,2'-azobisisoheptonitrile, 2-4 parts oftalcum powder, 4-5 parts of modified nano silicon dioxide, 3-5 parts of chloromethyl acetate, 4-6 parts of lauryl sodium sulfate, 5-7 parts of calcium carbonate, 8-10 parts of styrene, 1-2 parts of pearlized paste, 3-5 parts of silicon oil, 5-7 parts of calcium lignosulphonate and 4-6 parts of hydroxypropyl methyl cellulose. The acrylic plate can remove impurities, such as a polymerization inhibitor and moisture, so that the reflexivity of the plate is improved, the light attenuation degree is reduced, accordingly the light transmittance is improved, and can reach 94% or more, and meanwhile the acrylic plate has good mechanical properties.

Description

Technical field [0001] The invention relates to an acrylic sheet for light guide and a production method thereof. Background technique [0002] "Acrylic" is a transliterated word, and English is ACRYLIC. It is a chemical material. The chemical name is "PMMA", which is a polyacrylate, commonly known as "specially treated plexiglass". In the application industry, acrylic raw materials generally appear in the form of particles, plates, pipes, etc. Acrylic, also known as specially treated plexiglass, is a replacement product of plexiglass. Acrylic sheets can be perfectly combined with aluminum composite panel profiles, advanced screen printing, etc., to meet the needs of businesses. Acrylic blister is to improve the store level and unify the corporate image. A good form of outdoor advertising. In addition, acrylic is also used to make light boxes, etc. because of its light-transmitting properties. Acrylic industry will be used in more and more industries. If the light transmittanc...
