Problems solved by technology

[0002] At present, the water seepage of exterior walls, bathrooms and roofs commonly exists in various residential buildings after construction delivery. Although the existing polyurea waterproof materials can effectively solve this problem, the two-component materials Group A and Group B are in contact with the air. Mixing in a connected environment, but the polyurea waterproof construction equipment is heavy and bulky, and it is difficult to move and transfer during the construction process. During use, a three-phase four-wire 380V working voltage is required, and the working temperature is required to be controlled at 70°C. The output pressure is not lower than 36Mpa

Abstract

According to the method for mixing the bi-component polyurea in the spray gun and the bi-component polyurea spray gun, an A-group feeding pipe and a B-group feeding pipe are connected with a feeding port of a coupler, the coupler is connected with a mixing cavity, the mixing cavity is of a tubular structure, and the front end of the mixing cavity is connected with a discharging port of the coupler, so that materials sent out from the two discharging ports of the coupler are mixed in the mixing cavity; a plurality of X-shaped static mixers are installed in an inner hole of the tubular structure of the mixing cavity, and the rear end of the mixing cavity is connected with an atomizer. The double-component material mixing device has the advantages that double-component materials A and B which are mixed in the air originally are changed to be mixed in the mixing cavity, and the two materials can be mixed according to the proportion required by related technologies by respectively controlling the feeding speed and the feeding quantity of the materials A and B, so that the weight of the whole system equipment can be reduced, and the production cost is reduced. The double-component material is ensured to be mixed according to the proportion required by the technology, the mixing rate of the material A and the material B is improved, and the quality of the formed polyurea elastomer is further ensured.

Description

technical field [0001] The invention relates to a method for mixing two-component polyurea with a spray gun and a special spray gun thereof. Background technique [0002] At present, the water seepage of exterior walls, toilets and roofs is common in various residential buildings after construction delivery. Although the existing polyurea waterproof materials can effectively solve this problem, the two-component materials A and B are in contact with the air. Mixing is carried out in a connected environment, but the polyurea waterproof construction equipment is heavy and bulky, and it is difficult to move and transfer during the construction process. During use, a three-phase four-wire 380V working voltage is required, and the working temperature is required to be controlled at 70°C. The output pressure is not lower than 36Mpa. Contents of the invention [0003] The object of the present invention is to provide a method for mixing two-component polyurea with a spray gun an...
