Continuous Production Plant of Polyurethane Rigid Slab Foam

Abstract

The invention discloses a continuous production device of hard blocky polyurethane foam. A continuous foaming rack is arranged at the rear part of a polyurethane foaming pouring device, and comprises a cross rod used for bearing load, a lower delivery track used for conveying continuous blocky foam and a clamp track used for fixing a left frame and a right frame of foam for formation; during the foaming process, the lower delivery track and the left-and-right clamp track are kept synchronous; a paper releasing device is arranged at the front end of the continuous foaming rack, and is divided into a paper releasing mechanism for lower-layer paper, a paper releasing mechanism for upper-layer paper, and a left-and-right plastic film paper releasing mechanism; a left-and-right paper collecting mechanism is arranged at the rear end of the continuous foaming rack, and is synchronous with the clamp track. The continuous production device realizes the continuous production of a factory, is stable in quality, low in cost and high in production efficiency, and can realize large-scale production; besides, a top pressing device is arranged in a production line, the upper surface of produced hard foam is relatively flat, the material cutting ratio is high, and the product cost is reduced.

Description

technical field [0001] The invention relates to a continuous production device of polyurethane rigid block foam. Background technique [0002] Polyurethane rigid foam is mainly used in the heat insulation layer of household appliances, roof insulation and waterproof spray foam, pipe insulation materials, building panels, refrigerated vehicles and cold storage insulation materials, etc.; in recent years, with the building energy saving system engineering In building energy conservation, the heat (cold) lost by the building envelope accounts for more than 50% of the total building loss, and the walls of the envelope account for 2 / 3. Therefore, the insulation of the walls should be It is an important part of building energy saving. Due to its excellent physical properties and special processing and application characteristics, polyurethane rigid foam has continuously increased its application share in the building energy-saving market. As the most excellent thermal insulation...

Problems solved by technology

The main problems are: low production capacity, more labor, high labor intensity, low degree of automation, difficult quality control, which is not conducive to large-scale production, and the performance of foam is far inferior to that of continuous foaming block foam

At present, the production line related to polyurethane rigid foam has the application number of 201220195619.9 Chinese patent rigid foam polyurethane composite board automatic production line, which mainly produces composite board production line with polyurethane rigid foam as the core material and one side covered with cement fiber surface layer. The thickness of the produced board is relatively thin, and at the same time, due to the use of composite surface layer, the cost is high; in addition, due to the limitation of process conditions and curing cycle, the dimensional stability of composite board is poor
