Problems solved by technology

[0003] At present, the plastic material of plastic spectacle frames commonly used in the market is PA12, and some manufacturers often use PA12 direct injection molding to produce transparent spectacle frames. Although PA12 material has good toughness, there is still room for improvement in its toughness and light transmittance. At the same time, the spectacle frame directly injected with PA12 has poor yellowing resistance, so a high-elastic transparent spectacle frame material is proposed

Abstract

The invention discloses a high-elasticity transparent mirror frame material, and relates to the technical field of modified polyamide. The high-elasticity transparent mirror frame material is prepared from the following raw materials in parts by weight: 80-90wt% of PA12, 5-20wt% of polyethylene, 0.5-3.0 wt% of antioxidant, 0.1-0.5 wt% of anti-reflection agent and 1.0-3.0 wt% of white oil, and the anti-reflection agent is one or a mixture of more of 4-tert-butylbenzoic acid, sodium benzoate, organophosphate, adipic acid, diphenylacetic acid and sodium succinate. The high molecular weight polyethylene and the anti-reflection agent are matched for use, so that the crystallization behavior of the PA12 can be effectively changed, the crystallization rate of the PA12 is increased, the crystallization density of the PA12 is increased, the grain size of the PA12 is promoted to be micronized, meanwhile, the crystallization proportion of the PA12 is reduced, the modified PA12 has better transparency, and meanwhile, the toughness is improved on the premise that the rigidity of the PA12 is kept .

Description

technical field [0001] The invention relates to the technical field of modified polyamide, in particular to a highly elastic transparent mirror frame material. Background technique [0002] The spectacle frame is an important part of the glasses. It mainly plays the role of supporting the spectacle lens. The spectacle frame with a beautiful appearance can also play an aesthetic role. Its materials mainly include metal, plastic or resin, natural materials, etc. According to the style, it can be Divided into full frame, half frame, frameless and other types, glasses frame materials are required to have certain hardness, softness, elasticity, wear resistance, corrosion resistance, light weight, luster and good color, etc., so the use of light weight It is a good choice to make glasses frames with plastic with good performance. [0003] At present, the plastic material of plastic spectacle frames commonly used in the market is PA12, and some manufacturers often use PA12 direct ...
