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.
