Abstract

The invention provides a polyvinyl chloride lampshade with high light transmittance and a preparation method thereof. The lampshade comprises the following components in parts by weight: 100-120 parts of polyvinyl chloride, 10-13 parts of talcum powder, 10-13 parts of fumed silica, 1-2 parts of aluminum sulfate, 2-3 parts of sodium fluosilicate, 4-5 parts of polyurethane, 1-2 parts of polyether glycol, 4-5 parts of epoxy stearate, 0.3-0.5 part of lauryl dimethyl amine oxide, 0.1-0.2 part of zinc pyrithione, 0.4-1 part of diphenylmidazoline and 1-3 parts of polyamide wax micro powder. The lampshade provided by the invention is resistant to high temperature and poaching, and is high in light transmittance; most light emitted by a lamp can penetrate through the lampshade, so that a use ratio of electric energy is improved, a significant progression is achieved in the field of production of energy-saving and environment-friendly materials, and the lampshade is of great and practical significance.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a polyvinyl chloride lampshade with high light transmittance and a preparation method thereof. Background technique [0002] The lampshade is a protective device packaged around the lamp to protect the lamp. Due to its use characteristics, the lampshade must not only protect the lamp to a certain extent, but also have good light transmission and light scattering performance, so that the lamp The emitted light can be well diffused into the surrounding environment through the lampshade, so as to achieve a very good lighting effect or a beautiful landscape effect. The lampshade in the prior art has the technical defects of poor light transmittance and poor scattering performance, so that the light emitted by the lamp is blocked or absorbed, reducing the lighting efficiency of the lamp, and it is also a great waste of electric energy. Harness valuable energy resources. Contents o...
