Description

technical field [0001] The invention relates to the technical field of preparation and application of a polymer material, in particular to an antistatic material, a self-cleaning light diffusion plate prepared from the antistatic material and a preparation method of the light diffusion plate. Background technique [0002] At present, with the enhancement of awareness of environmental protection and energy saving, LED lamps are widely used due to their remarkable energy-saving effect. And to make the light of LED lights soft, it is usually designed to add LED lamp shades. However, these lampshades have insufficient light softness and loss of light energy to varying degrees during use, and especially after long-term use, a large amount of dust accumulates due to electrostatic adsorption, which aggravates the above defects. [0003] At present, the lampshades used are generally made of polystyrene resin (PS), polymethyl methacrylate (PMMA), polycarbonate (PC) and other similar...

Problems solved by technology

However, these lampshades have insufficient light softness and loss of light energy to varying degrees during use, especially after long-term use, a large amount of dust is accumulated due to electrostatic adsorption, which aggravates the above defects

[0003] At present, the lampshades used are generally made of polystyrene resin (PS), polymethyl methacrylate (PMMA), polycarbonate (PC) and other similar materials. PC, PMMA, and PS have high light transmittance. , although the loss of light energy can be effectively avoided, but the light cannot be effectively soft enough for human eyes. LED lights still have strong and dazzling defects, and the problem of light energy loss caused by electrostatic adsorption of dust accumulation after long-term use

[0004] For this reason, materials for processing and modifying PC, PMMA or PS have appeared one after another in recent years. The processing modification is mainly carried out by adding some inorganic additives, such as: silicon dioxide, barium sulfate , adding these inorganic nanoparticle additives, the light will undergo countless light refraction through the surface of these tiny particles to achieve light diffusion, that is, play the role of uniform light to make the light soft, but when applying such modified materials, due to Light cannot penetrate these inorganic nanoparticles, and the light penetration is greatly weakened, resulting in a large loss of light energy. At the same time, there is also the defect that electrostatic adsorption and accumulation of dust affect the light transmittance and loss of light energy.

[0005] In addition, in order to avoid the above defects, there is a technology of adding organic light diffusing agent to materials such as PC, PMMA or PS for processing and modification. Invention patent ZL201010218327.8 discloses a high-haze and high-transparency LED lamp tube The material and its preparation method mainly take PC as the matrix, add PMMA microbead light diffusing agent, color protection agent and other auxiliary agents, and extrude granulation through melt blending; There has been some progress in light transmittance, but it cannot avoid the influence of electrostatic adsorption and accumulation of dust during use, so it is not suitable for long-term use and promotion

Invention patent ZL201010140129.4 provides a high luminous flux, anti-glare polycarbonate and its preparation method, first prepare polycarbonate resin light diffusion masterbatch, and then add polycarbonate on the basis of polycarbonate resin light diffusion masterbatch Resins and additives, mainly based on PC, using spherical methyl silicone resin or cross-linked methyl methacrylate microspheres or one or two composite light diffusing agent additives; the invention is effective to a certain extent It eliminates glare glare, low light loss and high luminous flux. However, it still has the problem of electrostatic adsorption, which seriously affects its long-term use effect.

Invention patent ZL201110151541.0 also discloses a flame-retardant light-diffusing polycarbonate resin composite material for LED lamps and its preparation method, which effectively improves the flame-retardant performance of light-diffusing PC materials. Similarly, electrostatic adsorption and light loss cannot be avoided. question

In addition, invention patent ZL200880106372.5 discloses a resin composition for a light diffusion plate, a light diffusion plate and its manufacturing method. Although the invention raises the antistatic problem of the light diffusion plate, its single-layer structure and manufacturing method are not Did not effectively solve the antistatic problem, and did not achieve better results
