Production process and painting equipment of composite heat-insulation board

Abstract

The invention discloses a production process and painting equipment of a composite heat-insulation board. The production process of the composite heat-insulation board comprises the following steps of: (a) cutting a heat-insulation layer, and coating an adhesive on the upper surface of the heat-insulation layer; (b) preparing protective layer slurry, injecting to a mold, carrying out pressure filtration and molding; (c) laminating the heat-insulation layer and the protective layer; (d) maintaining; and (e) coating paint on the upper surface of the laminated protective layer obtained in the step (d) of the heat-insulation board and drying. The painting equipment comprises a conveyer belt for conveying the heat-insulation board, wherein a coating roller wheel which is in driving connection with a driving device is arranged above the front end of the conveyer belt, a gap, matched with the thickness of the heat-insulation board is formed between the coating roller wheel and the conveyer belt, a charging device for supplementing the paint is arranged above the coating roller wheel, the coating roll wheel comprises a roller wheel shaft at the center and an elastic roller body, and a silk screen is coated on the external surface of the roller body. According the invention, the working procedure is simple, the production efficiency is high, and the painting equipment has good coating effect and high coating efficiency.

Description

technical field [0001] The invention relates to the technical field of building thermal insulation products, and specifically relates to a production process and coating equipment of a composite thermal insulation board. Background technique [0002] Roof engineering is an important part of modern energy-saving buildings. The thermal energy consumption of the roof accounts for 30% to 40% of the total energy consumption of the top floor. The thermal insulation performance of the roof engineering is directly related to the energy-saving effect and living comfort of the top floor residents. good or bad. [0003] In recent years, the practice of inverted roofing has been widely used, which is characterized in that the waterproof material is placed above the structural layer, below the thermal insulation material, and doubles as an air barrier. It can not only make up for the traditional roofing method where the thermal insulation material is placed between the air barrier layer...

AI Technical Summary

Problems solved by technology

From the perspective of a large number of practical engineering applications, although the inverted roof has many advantages compared with the traditional roofing method, there are still shortcomings that need to be continuously studied and improved. For example, due to the need for roof drainage, the roof surface must be It is made into a wave shape, and the laying of large insulation boards is prone to problems such as false paving, warping, and thermal bridges caused by disconnection of insulation boards at the water line.

Second, the use of fine stone concrete as the protective layer has a large amount of wet work, complicated procedures and inconvenient maintenance.

The third is to use pebbles and natural stones or prefabricated concrete blocks on the top. The disadvantages of these methods are that the stability between the protective layer and the insulation layer is poor, and the surface is prone to warping and cracking. Ergonomics

[0006] The color finishing layer of composite insulation boards is generally realized by coating paint. The surface beautification of existing composite insulation boards is mostly done manually, and some insulation boards are provided with patterns on the surface, which are uneven. Uneven, poor coating quality, low efficiency
