Abstract

The invention discloses a PC sheet material with a coating and a preparation method of the PC sheet material. The PC sheet material comprises a sheet material main body layer which is a PC sheet material main body layer, and a heat insulating coating, wherein the heat insulating coating and the sheet material main body layer are extruded and formed, and the heat insulating coating is prepared by mixing an infrared absorption agent and PC; the percentage by weight of the infrared absorption agent is 0.5-5%, and the PC sheet material with the coating is prepared by the following method; a double screw extruder is used for compounding the infrared absorption agent to PC resin so as to prepare PC agglomerates; on a PC sheet material extruder, the PC agglomerates are uniformly coated to the upper surface of the sheet material main body layer. The PC sheet materials with the coating, prepared by the method disclosed by the invention, has the advantages of low proportion of an infrared additive, simple preparation method, good thermal insulation effect, high transmittance and low product cost.

Description

technical field [0001] The invention relates to a PC board, more specifically a coated PC board. Background technique [0002] Due to the continuous rise of ambient temperature and the problem of energy loss, heat insulation and energy saving have become a social issue of concern. The development of heat insulation panels and their high potential market prospects have become a matter of great concern to people. Plates are widely used and can be used in ships, vehicles, construction plants and houses, etc. For the current environment of energy shortage, its economic benefits are also more significant. [0003] In hot summer or cold winter, the outdoor temperature is unbearable for ordinary people. Therefore, in summer, it is often necessary to turn on the air conditioner indoors to reduce the temperature to a comfortable level for the human body. In winter in the north, collective heating equipment is needed to heat the house. In this case, a poorly insulated room from the o...
