Abstract

The invention discloses a plastic with the flame-retardant characteristic and high transmittance within a specific wavelength range, and a manufacturing method thereof. The plastic comprises, by weight, 60%-97% of a plastic raw material, 0.1%-35% of a flame retardant, 0.2%-2% of a surface-treating agent, 0.2%-2% of an auxiliary agent and 0.2%-2% of an absorbent with a specific wavelength of 300-2,500 nm. A preparation technology of the plastic is shown in the description. The plastic has excellent flame-retardant performance, and has high transmittance within the specific wavelength range.

Description

technical field [0001] The invention relates to plastics, in particular to plastics with flame-retardant properties and high transmittance of wavelengths within a specific range and a manufacturing process thereof. Background technique [0002] At present, there are plastics with high transmittance in certain wavelength ranges obtained by adding small organic molecules in China, but most of them are conventional plastic raw materials, which do not have flame retardant and fireproof properties, which limits their scope of use. The addition of ordinary flame retardant additives will directly affect the transmittance of plastics. We add special flame retardant additives and specific electromagnetic wave absorbing materials to make these materials have a higher transmittance without affecting the original high transmittance within a specific range. High flame retardant and fireproof performance, thus expanding its application range and improving electrical performance. And by s...
