Abstract

The invention discloses a photodiffusion polycarbonate composite material and a manufacture method of a photodiffusion light guide plate for building materials. The composite material is composed of the following components: 85-95% of polycarbonate resin, 0.5-0.8% of photodiffusion agent, 0.2-3% of silicone master batch, 0.3-3% of light stabilizer, 0.1-1% of heat stabilizer and 0.1-1% of processing aid. The manufacture method comprises the steps of: (1) preparing the photodiffusion polycarbonate composite material; (2) manufacturing into a light guide plate mold according to component drawings; and (3) carrying out one-time extrusion shaping on the photodiffusion polycarbonate composite material in a universal extruder by virtue of the light guide plate mold to obtain the component; assembling, testing and packaging to obtain a finished product. The invention has the advantages that: by the addition of the photodiffusion agent, the haze of the light guide plate is increased, the transmittance is maintained, the lighting property is maintained and the injury of strong light to eyes is avoided; by the addition of the composite light stabilizer, the service life of the light guide plate is prolonged; and by the addition of the silicone master batch, the melt flowability and demolding property are improved and the shaping and processing performances of the light guide plate are improved.

Description

[0001] technical field [0002] The invention relates to the technical field of polymer materials, in particular to a method for manufacturing a light-diffusing polycarbonate composite material and a light-diffusing light guide plate for building materials. Background technique [0003] Polycarbonate resin, referred to as PC, is one of the five major engineering plastics. As a widely used material, PC is an amorphous thermoplastic resin with excellent comprehensive properties. It has excellent electrical insulation, extensibility, dimensional stability and Chemical corrosion resistance, high strength, heat resistance, transparency and cold resistance; at the same time, it also has the advantages of self-extinguishing, flame retardant, non-toxic, and colorable. [0004] As a transparent material, PC can be used as a light guide plate for homes, factories, and carports. As a material for outdoor use, it has high requirements on light aging resistance, strength and toughness. ...
