Flexible coil facing polyurethane thermal insulation and decoration integrated board and its preparation process

Abstract

The invention discloses a polyurethane thermal insulation and decoration integrated panel with a flexible coil finish and a preparation process thereof. The integrated panel comprises: a bottom reinforcement layer, a three-dimensional grid cloth skeleton, a polyurethane thermal insulation layer and a flexible coil decorative surface layer. Its preparation process: preparation of flexible coiled material decorative surface layer; laying the bottom surface reinforcement layer on the lower layer of the polyurethane assembly line, and then laying the three-dimensional mesh cloth skeleton and the flexible coiled material decorative surface layer on the bottom surface reinforcement layer in sequence, and finally laying the three-dimensional mesh cloth skeleton Medium-sprayed polyurethane foam forms a flexible coil facing, heat preservation and decoration integrated board. Through the above method, the present invention can continuously supply materials by crimping, the process is simple, the efficiency is high, the quality is stable, and the production efficiency of the factory is significantly improved; not only the overall impact resistance of the board is improved, the system is safe, and it is easy to promote, and it can be directly cut on the insulation layer The tongue and groove, the installation of fasteners, does not damage the insulation layer, and abandons the backing material, which significantly reduces the engineering cost.

Description

technical field [0001] The invention relates to the field of building heat preservation, in particular to a polyurethane thermal insulation and decoration integrated panel with a flexible coil facing and a preparation process thereof. Background technique [0002] The traditional thermal insulation and decoration integrated board needs a rigid liner to improve the impact strength of the integrated board and provide a tongue and groove for keel installation. The commonly used rigid lining boards are calcium silicate boards, cement fiber boards or stone materials. These materials cannot be curled and continuously supplied, and the production efficiency of the factory is low; and the decorative integrated boards made are too heavy, which is extremely inconvenient for transportation and construction; This type of board also requires a special keel, which significantly increases the project cost. [0003] The prior art discloses a production method of a rigid polyurethane therma...

Problems solved by technology

The commonly used rigid lining boards are calcium silicate boards, cement fiber boards or stone materials. These materials cannot be curled and continuously supplied, and the production efficiency of the factory is low; and the decorative integrated boards made are too heavy, which is extremely inconvenient for transportation and construction; It requires a special keel, which significantly increases the project cost

[0003] The prior art discloses a production method of a rigid polyurethane thermal insulation and decoration integrated board with the application number 201210079977.8, which is to first lay a grid cloth thick film cement mortar on the polymer coil, and then lay the grid cloth Brushing the finishing layer to form a flexible coil, this method has many procedures, and the polymer cement mortar is too flexible, the impact strength of the decorative plate cannot pass; the polymer cement mortar is too flexible, and the winding is easy to crack and fall off , and the integrated board proposed in this patent is directly constructed with a thin plastering system, which poses a great safety hazard
