Abstract

The invention relates to a method for preparing a photovoltaic matched PVC (polyvinyl chloride) tile by using a weather-resistant reinforced modified filler, which comprises the following steps of: mixing and stirring 100-125 parts by weight of PVC resin powder, 3-6 parts by weight of a stabilizer, 0.8-1.5 parts by weight of a processing aid, 6-8 parts by weight of a flexibilizer, 0.5-0.8 parts by weight of a lubricant, 0.1-2 parts by weight of pigment and 0.1-0.3 parts by weight of a weather-resistant aid at high speed for 3 minutes, then adding 10-100 parts by weight of modified calcium carbonate, continuing to stir for 5 minutes to obtain a mixture, pouring the mixture into an extruder, and heating, plasticizing and extruding to obtain a molten material; and feeding the prepared molten material into a flat die to form a hot sheet, then feeding the hot sheet into a tile die, and carrying out tile wave compression molding, cooling, traction and cutting to obtain a photovoltaic matched PVC tile prepared from a weather-resistant reinforced modified filler. Through inorganic and organic modification, the PVC tile is endowed with excellent weather resistance.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a method for making photovoltaic matching PVC tiles with weather-resistant enhanced modified fillers. Background technique [0002] Photovoltaic power generation is a clean energy and will gradually become mainstream. Photovoltaic panels are currently generally installed on the color steel roof of steel structure factories. The service life of color steel will not exceed 15 years. If it is in a corrosive industrial plant, the service life of color steel will be shorter, while the service life of photovoltaic panels is 25 years. This means that the watts must be replaced 2-3 times during the life cycle of the photovoltaic panel, which is troublesome to disassemble and assemble, and the cost is very high, causing a lot of waste. Based on this premise, the present invention provides a treatment method for weather-resistant enhanced modified fillers, and a PVC ...
