Problems solved by technology

However, the construction environment is often different. When the temperature is low, the waterproof coating solidifies faster. During the separate construction of the waterproof coating and the defoaming layer, it is easily affected by the faster solidification of the waterproof coating. Between the waterproof coating and the defoaming layer The adhesive force of the waterproof layer is weak, which causes bubbles to appear easily between the waterproof coating and the defoaming layer. After the air in the bubbles is heated and expanded, the bubbles in the waterproof layer rupture, and a large number of penetrating pores will be generated, resulting in the failure of the waterproof layer.
Therefore, the existing technology has the problem that the waterproof effect of the waterproof layer is poor after construction.

Abstract

The invention discloses a waterproof coating construction method, which comprises the following steps: pretreatment, waterproof coating smearing and composite layer laying, and also provides a laying device, which comprises a rack, an uncoiling assembly and a laying assembly. The waterproof coating has the beneficial effects that before the waterproof coating is laid on the base layer, the cooling time of the waterproof coating is shortened, and meanwhile, the heat of the waterproof coating is prevented from being absorbed by the base layer before the waterproof coating is in contact with the carrier layer, so that the waterproof coating can be effectively prevented from being cooled in advance, and hollowing caused by insufficient bonding force between the waterproof coating and the carrier layer is prevented; and the waterproof effect of the waterproof layer after construction is relatively high.

Description

technical field [0001] The invention relates to the technical field of construction methods, in particular to a construction method of waterproof paint and a laying device for implementing the method. Background technique [0002] Waterproof coating is a kind of civil engineering material, which is used to waterproof the building surface by spraying or brushing. In the traditional construction method of painting the waterproof coating on the cement base surface, the cement base surface is pretreated to reduce the air bubbles formed after the waterproof coating is painted, so as to improve the waterproof performance of the waterproof coating after cooling and solidification. [0003] The Chinese invention patent application document with the announcement number of CN113898186A discloses a water-vapor isolation-based defoaming method for waterproof coatings, which includes step 1: pretreatment of the base layer; step 2: laying waterproof paint on the surface of the base layer ...
