Production line of glass wool rock wool composite PU hard foam thermal insulation plate

Abstract

The invention provides a production line of a glass wool rock wool composite PU hard foam thermal insulation plate. The production line comprises a lower cement plate feeding device arranged on the front end of a first transmission device; the first transmission device is provided with a glue spraying and curing device, a composite plate adhering and rolling device, and an upper surface plate feeding device in sequence from front to rear; a dual crawler pressing machine is arranged between the tail end of the first transmission device and a second transmission device; the second transmission device is sequentially provided with a primary trimming and cutting chamber and a tracking-cutoff and cutting device from front to rear; and the tail end of the tracking-cutoff and cutting device is connected to a material receiving device through a secondary trimming and cutting device. The production line has the advantages of convenient construction, good thermal insulation effect, and low production cost, and the produced thermal insulation plates meet the national environmental protection standards.

Description

technical field [0001] The invention belongs to the technical field of thermal insulation composite boards for external walls, and in particular relates to a continuous production line of glass wool and rock wool composite PU rigid foam thermal insulation boards. Background technique [0002] In my country's wall thermal insulation technology, more than 90% of the traditional thermal insulation technology uses organic materials such as EPS, XPS, and PU. Because the use of organic thermal insulation materials is prone to fire accidents, it does not meet the fire protection requirements. Therefore, it has been changed to mainly use inorganic thermal insulation materials, but most of the inorganic thermal insulation materials have problems such as high thermal conductivity, poor thermal insulation performance, and water absorption failure of the insulation layer; There are also problems with mechanical properties in use. At present, the energy-saving standard of residential bu...

AI Technical Summary

Problems solved by technology

In the prior art, the double sides of inorganic fireproof materials such as rock wool or glass wool are compounded with cement paste materials. The manufacturing process of this kind of composite insulation board is complicated. The maintenance period is long, resulting in a large production plant, low efficiency, high cost, and poor waterproof performance; there are also inorganic insulation boards pasted and fixed on the outer wall. Although the problem of fire prevention is solved, due to its high thermal conductivity and thermal insulation Defects such as poor performance, water absorption failure of the insulation layer and easy cracking and falling off, short service life, complicated construction, long construction period, high application cost, high maintenance and replacement costs
