Problems solved by technology

However, the flame retardant performance of the light-diffusing PP material itself is not good, and there will be a greater safety hazard in terms of fire prevention; in addition, due to the characteristics of the material, the PP material is easy to be scratched when it is touched by hard objects such as nails. , which seriously affects the appearance and affects the light diffusion effect; making the light diffusion PP material have more restrictions in use

Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] An embodiment of the present invention provides a flame-retardant and scratch-resistant light-diffusing PP material, which includes the following components by weight:

[0017]

[0018]

[0019] The above-mentioned light-diffusing PP material of the present invention uses PP material as the base material, and adds various synergistic functional additives such as nanometer antimony trioxide, organosilicon polymer, and acid absorbing agent, so as to achieve a stable improvement in the flame retardancy of the PP material. After improved scratch resistance, it can also have excellent light effect performance.

Abstract

The invention provides a flame-retardant scraping-resistant photodiffusion PP material and a preparation method thereof. The flame-retardant scraping-resistant photodiffusion PP material comprises the following components in parts by weight: 75-95 parts of PP, 2-10 parts of a brominated flame retardant, 0.5-5 parts of nano antimonous oxide, 0.2-5 parts of an organosilicon polymer, 0.2-1 part of flame-retardant oil, 0.1-0.5 part of an antioxidant, 0.1-0.5 part of a photostabilizer, 0.1-0.5 part of a transparent nucleating agent, 0.1-0.5 part of a lubricant, and 0.1-0.5 part of an acid absorbent. By selecting specific type of functional additives and under synergistic mechanism of all raw materials, the PP material finally has the advantages of high transparency and haze, flame retardance, scraping resistance, low cost, excellent toughness, light density, excellent yellowing resistance, high thermal deformation temperature, no toxicity and the like and is recyclable, and the usage performance of the PP material can be greatly promoted.

Description

technical field [0001] The invention belongs to the technical field of engineering plastics, and in particular relates to a flame-retardant, scratch-resistant, light-diffusing PP material and a preparation method thereof. Background technique [0002] When the light passes through the diffusion layer of the plastic substrate and encounters a medium (diffusion particles) with a different refractive index, multi-angle and multi-directional refraction, reflection and scattering will occur, so that the point light source can achieve the effect of light diffusion , to provide a more uniform and comfortable light output effect for lighting fixtures. The materials of the mainstream diffusers on the market are PMMA, PC, PET and so on. [0003] Under the premise of ensuring the light diffusion effect and light transmittance (85%), the light-diffusing PP material has a lighter density of 0.90 (PC density 1.2, PMMA density 1.19) than PMMA and PC materials on the market, and 100% can ...
