Production technology of waterproof and heat-insulated integrated board

Abstract

The invention discloses a production technology of a waterproof and heat-insulated integrated board. The production technology comprises the following steps of: firstly, compositing an enhanced isolating material at one side of a waterproof roll; pre-heating the waterproof roll composited with the enhanced isolating material by a pre-heating device; compositing an heat-insulated material at one side of the waterproof roll composited with the enhanced isolating material after pre-heating; and finally, covering another pre-heated waterproof roll on the surface of the heat-insulated material. By providing the enhanced isolating material at one side of the waterproof roll, not only can the bonding strength between the enhanced isolating material and the waterproof roll be enhanced, but also the waterproof roll and the heat-insulated material can be effectively isolated; the condition that the waterproof roll is contacted with the heat-insulated material for a long time to cause chemical reaction can be avoided; a plasticizer inside the roll is prevented from migrating; the quality of the product is ensured; a procedure of pre-heating the waterproof roll is added before the waterproof roll and the heat-insulated material are composited; and the phenomenon that a waterproof layer and an insulating layer are stripped after the board is molded can be avoided, and the performance and quality of the board are further improved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a production process of a waterproof and thermal insulation integrated board. Background technique [0002] At present, the general production method of waterproof insulation board is to spray polyurethane material on the surface of the waterproof membrane, and then cover a layer of waterproof membrane, and the whole is formed by foaming. For example, Chinese patent document CN 102454234A discloses a "preparation method of polyurethane waterproof insulation board", comprising the following steps: (1) first coating a waterproof adhesive layer on one side of the easy-to-stick layer to obtain a waterproof and easy-to-stick composite layer, (2) the shaft roll wound with waterproof coiled material or metal sheet, or the shaft roll of the waterproof and easy-to-paste composite layer obtained in step (1) is placed on the foaming and curing box inlet end. On the shelf, pull out the wat...

AI Technical Summary

Problems solved by technology

The disadvantage of the above method is that: after the waterproof insulation board is formed, the waterproof coiled material and the thermal insulation material are prone to peel off, which affects the appearance and performance of the product; some waterproof coiled materials and thermal insulation materials are difficult to bond, for example, polyethylene polymer coiled material It is difficult to bond with polyurethane materials, and the plasticizer contained in the membrane may migrate; some waterproof membranes will chemically react with insulation materials, for example, asphalt-based waterproof membranes will be compounded with polyurethane for a long time Highly likely to react chemically with polyurethane, affecting the performance and quality of the waterproof insulation board
