Problems solved by technology

[0004] The problem to be solved by the present invention is that when the two-component nanometer material is sprayed, the material is not mixed uniformly in the spray gun, and it is easy to stick, agglomerate and block, and it is impossible to control the ratio of the two-component material and the spraying amount, and the structure of the spray gun is complicated and inconvenient to assemble, disassemble and clean. or replace

Embodiment approach 1

[0021] The present invention is based on the technical scheme and its attachments Figure 1~6 , Using high-quality steel, refined by mechanical manufacturing methods, the connection part of the nozzle and the gun body is connected by a matching thread, but the entire spray gun system should be made according to the pressure system, and the production and installation of the spray gun and parts should be accurately matched. In addition, the spray gun is composed of a pressured two-component nanomaterial storage tank and a guide tube connected to the spray gun.

[0022] in Figure 1~6 The main structure of the entire spray gun is: there is a spray head 1 with a positive rotation mixing reaction chamber 16 and a reverse rotation mixing reaction chamber 13; there is a spray head 1 connected to the spray head 1 with a first gun body silo 26 It is connected with the second gun body silo 30, the first gun body silo introduction channel 6 and the second gun body silo introduction channel 7 ...

Embodiment approach 2

[0028] If the spray gun made according to the first embodiment is used for filling and plugging the gaps in coal mine roadways, mining areas, etc., a nano material storage tank should be made, and a material storage tank should be filled or injected with polyurethane elastic prepolymer 3~ 5Kg and trichloroethylene solvent 0.5~2.5MPa, another material storage tank is filled or injected with diamine or glycol crosslinking agent 0.5~2Kg, the pressure in the material storage tank is 1.5~2.5MPa, in the material storage tank There are valves and guide tubes connected to the spray gun. When spraying, open the valve on the material storage tank, and then introduce the first gun body silo on the spray gun body into the flow channel 6 and the second gun body silo into the flow channel The first gun body silo introduction runner control valve 4 and the second gun body silo introduction runner control valve 5 on 7 are opened and adjusted the material ratio, and then adjust the size of the spr...

Embodiment approach 3

[0030] Using the spray gun made in Embodiment 1, according to the method of use in Embodiment 2, if a temporary insulation tent is set up in the rescue and relief process, the nano material storage tank can be filled or injected with MDI: 5-10kg, aerosol (one Chlorodifluoromethane): 0.5~1.0kg, pressure: 1.5~2.5MPa; another material storage tank (1) is flushed with spraying combination polyether; 4~8kg, aerosol (monochlorodifluoromethane): 2 ~3kg, pressure: 1.5~2.5MPa, spraying on the frame with straw mat, woven belt, canvas, etc. as the base material can quickly build a temporary tent with cold insulation and heat preservation.

Abstract

The double component nanometer material spray gun has one nozzle with material mixing reaction bin; one gun body with the first material bin and the second material bin, material bin leading flow channel and flow channel controlling valve; and one gun handle hinged to the gun body and with gun switch and spray amount controller. The material mixing reaction bin makes the nanometer materials mix and react homogeneously. The spray gun is matched with pressurized material supply system for spraying various kinds of double component material.

Description

Technical field [0001] The invention relates to a self-spraying two-component material spray gun, in particular to a two-component nano material spray gun comprising a spray head, a gun body and a handle. Background technique [0002] In the prior art, the spray gun applied to nano-scale materials has a wide range of spray materials and spray objects. Especially when the material reaches the nano-level, the material is very fine and can be double-grouped in the spray gun. The self-spraying spray gun that mixes evenly divided nano-materials has not been reported. CN2505181Y's "foam caulking agent spray gun" utility model patent, including gun barrel, gun body and handle, its main structure is that the part of the handle contacting the palm of the human hand is arc-shaped outwardly protruding. The contact side is provided with a blocking block, which is located near the bottom of the handle end when the trigger approaches the handle. When the hand is gripped, the blocking block can...
