Abstract

The invention discloses a microcellular foaming self-cleaning type plastic plate. The microcellular foaming self-cleaning type plastic plate is prepared from raw materials in parts by weight as follows: 3-4 parts of dibutyl phthalate, 1-2 parts of azodicarbonamide, 3-4 parts of pentaerythritol, 0.4-1 part of zinc dialkyl dithiophosphate, 1-2 parts of calcium ricinoleate, 10-14 parts of titanium tetrachloride, 3.7-4 parts of ferric chloride, 6-8 parts of hydrogen peroxide with concentration of 25%-30%, 7-9 parts of methyl methacrylate, 0.1-0.2 parts of azodiisobutyronitrile, 100-130 parts of polyvinyl chloride, 0.7-1 part of a silane coupling agent kh5600, 0.3-1 part of stannous sulfide, 0.7-1 part of tert-butyl hydroquinone, 3-5 parts of ammonium polyphosphate, 0.6-1 part of polysorbate 80 and 2-4 parts of calcium borate. Added Fe-doped titanium dioxide has quite good photocatalysis capacity, and pollutants attached to the surface of the plate can be degraded and removed, so that self-cleaning performance is realized.

Description

Technical field [0001] The invention relates to the technical field of board, in particular to a micro-foaming self-cleaning plastic board and a preparation method thereof. Background technique [0002] Titanium dioxide is a transition metal oxide and also a semiconductor material. Because of its good biocompatibility, resistance to chemical corrosion, and harmlessness to the human body, it is also rich in materials due to the rich content of titanium sources. And because of its low price, it has attracted widespread attention. The application of titanium dioxide is reflected in all aspects of people's lives. At present, the use of titanium dioxide inorganic products has reached the world's leading level. Due to the characteristics of titanium dioxide, it can be used as a very important inorganic chemical material, so it has a huge influence and application in many fields such as national defense aviation, industrial production, and cutting-edge technology. Titanium dioxide can ...
