Problems solved by technology

[0003] 1. The thermal insulation structure layer consists of the connection interface layer, the fiber spray layer (thermal insulation structure) and the waterproof mortar layer, which need to be constructed three times, which is complex, labor-intensive and expensive
[0004] 2. The waterproof mortar layer that plays a waterproof role is easily damaged by bumps during construction, and the waterproof mortar layer is easy to crack under the condition of external temperature changes. If it is damaged or cracked, the thermal insulation structure will reduce or even lose its thermal insulation performance after absorbing water or being damp.
[0005] 3. The construction process of waterproof mortar is seriously polluted

Abstract

The invention discloses a waterproof and insulating structure for a curtain wall. The waterproof and insulating structure is formed by mixing cellucotton which is subjected to waterproofing treatment by using organic silicon emulsion and adhesive of the cellucotton, and then directly spraying a mixture outside a wall body of the curtain wall, and is simple in structure and convenient to produce. The invention also discloses a manufacturing method for the waterproof and insulating structure. The method comprises the following steps of: performing waterproofing treatment on the cellucotton, spraying the cellucotton and the adhesive of the cellucotton out by respective pipelines, mixing in space from a sprayer to the wall body to ensure that the adhesive is uniformly coated on the surface of the cellucotton, and automatically adhering the cellucotton onto the wall body when reaching the wall body to form the waterproof and insulating structure. By the method, the insulating construction process of the wall body of a curtain wall structure is simplified, the manufacturing cost and time of engineering can be reduced greatly, and the defect that the adhesive is not coated uniformly, so that an insulation layer drops in the prior art can be avoided.

Description

technical field [0001] The invention relates to an external wall thermal insulation structure, in particular to an external wall thermal insulation structure provided with a curtain wall. Background technique [0002] In the patent No. ZL201020262165.3, a Chinese patent titled fireproof and thermal insulation curtain wall discloses a curtain wall thermal insulation structure commonly used at present. The thermal insulation structure layer of this curtain wall is composed of three layers: connecting interface layer, fiber spray layer (thermal insulation structure) and waterproof mortar layer. There are following disadvantages: [0003] 1. The thermal insulation structure layer consists of the connection interface layer, the fiber spray layer (thermal insulation structure) and the waterproof mortar layer, which need to be constructed three times, which is complicated, labor-intensive and expensive. [0004] 2. The waterproof mortar layer that plays a waterproof role is easi...
