Problems solved by technology

[0005] The Chinese invention patent with the publication number CN104324628A discloses a static mixing device used in the preparation process of two-component polyurea, which adopts synchronous double plunger push rods, which better solves the problem of the synchronization of the A lifting pump and the B lifting pump. Requirements, but because of the same single-cylinder piston pump used, it can only absorb and spray materials intermittently. When the material is sucked, stop spraying, and materials A and B are easy to polymerize and block in the mixing tube (5)
For this reason, it is still difficult to operate
[0006] Imported polyurea spraying equipment has the same basic structure as domestic equipment except for the addition of precision electronic control devices. The operation is complicated and the price is high, which domestic construction teams cannot afford.
The existing domestic polyurea spraying equipment cannot be used by workers without three or five years of practical experience
[0007] Polyurea spraying is in the ascendant, but it is difficult to operate and easy to damage. Existing polyurea spraying equipment has become a bottleneck restricting the development and application of polyurea spraying

Description

technical field [0001] The invention relates to a polyurea spraying equipment, a spraying method and a corresponding polyurea composite waterproof layer mechanism. Background technique [0002] Polyurea elastomer waterproof material is a two-component elastomer material formed by the polymerization of components A and B. It can be used alone or combined with other materials as waterproof coatings on the surface of concrete or other substrates, linings, and medium-resistant materials. Forms hard coating films of different thicknesses and can be applied to various occasions and to treat suitable substrates. [0003] However, the polyurea elastomer waterproof material needs to be sprayed with special spraying equipment. The commonly used domestic polyurea spraying equipment includes A bucket, B bucket, A pump, B pump, compressed air tank and spray gun, and A bucket. The pump, B lifting pump, and compressed air tank are respectively equipped with inlets and outlets. The spray g...
