Problems solved by technology

In actual work, the viscosity of glue A and glue B is significantly affected by the ambient temperature, for example, the temperature difference between day and night can reach 10°C in a day, and the temperature can reach 40°C or even greater throughout the year, and The viscosity of glue A and glue B is directly affected by the temperature. In the existing technology, glue A and glue B are pushed to the rubber mixing part by air pressure for mixing. Since the viscosity of glue A and glue B changes with the ambient temperature, the two are mixed. It is difficult to control the ratio of AB glue stably, resulting in poor curing effect of AB glue, poor bonding effect, and affecting product quality

Embodiment 1

[0032] This embodiment discloses a method of mixing AB glue with constant pressure and temperature adjustment. The commercially available AB glue is purchased from Dongguan Yantai Adhesive Co., Ltd., and the production model is TA-860. Clean the moisture, dust, oil stains, rust spots and other dirt on the surface of the bonded object, and keep it clean, dry and smooth. When using, mix and stir components A and B according to the ratio of 1:1, and apply it on the surface of the adherend. When bonding, it can be rotated and matched as much as possible. The glue is initially solidified in 3-6 minutes, and the usable strength can be reached in 1 hour. 24 hours to reach optimal strength. Can be used at -60°C to +110°C. (do not mix a large amount of glue at one time)

[0033] A method of isobaric and temperature-adjusting mixed AB glue, used to realize the device of the present embodiment such as Figures 1 to 4 shown, including the following steps:

[0034] A. Provide an A rubb...

Embodiment 2

[0049] The main difference between this embodiment and embodiment 1 is that the constant heating temperature of A glue is T 1 , the constant heating temperature of glue B is T 2, the air pressure in the A rubber hose 2 and the B rubber hose 3 is P, and the flow rate V of the A glue and the B glue 1 And the flow rate V of AB glue 2 , see Table 1 for details.

Embodiment 3

[0051] The main difference between this embodiment and embodiment 1 is that the constant heating temperature of A glue is T 1 , the constant heating temperature of glue B is T 2 , the air pressure in the A rubber hose 2 and the B rubber hose 3 is P, and the flow rate V of the A glue and the B glue 1 And the flow rate V of AB glue 2 , see Table 1 for details.

Abstract

The invention discloses a method of mixing AB glue through isobaric temperature regulation, which includes: A) providing an A glue tube and a B glue tube in same size and shape; B) providing a gas source, which communicates the upper ends of the A glue tube and the B glue tube, wherein the barometric pressures into the A glue tube and the B glue tube by the gas source are equal; C) regulating thetemperature of A glue in the A glue tube to be T1, constantly, with a group of constant temperature heating members, and regulating the temperature of B glue in the B glue tube to be T2, constantly, with another group of constant temperature heating members, so that the A glue and B glue are same in viscosity; D) turning on the gas source which communicates the A glue tube and the B glue tube, sothat the flow rates of the A glue, pushed from the A glue tube by air pressure, and the B glue, pushed from the B glue tube by equal air pressure, are equal; E) enabling the A glue and B glue to be mixed on a mixing component in a contact manner. The method, at constant temperature, stably controls the flow rates of the A glue and B glue by regulating the barometric pressures, thus accurately controlling the ratio of the A glue and B glue. A device is simple in structure and low in cost.

Description

technical field [0001] The invention relates to a mixing device, in particular to a method for mixing AB glue with constant pressure and temperature regulation. Background technique [0002] The two-component adhesive is also called AB glue. The glue and the hardener are mixed and hardened to obtain a normal temperature hardening glue. AB glue with acrylic acid, epoxy, polyurethane and other components is commercially available. [0003] The mixing method of the existing AB glue has different viscosities between the glue and the hardener at different temperatures. In order to maintain a suitable ratio between the glue and the hardener and have a good and stable bonding effect, it is necessary to adjust the glue and the hardener frequently. Only when the flow rate is high, the ratio of the two can be ensured, which is inconvenient to use. [0004] Glue A and glue B should be mixed evenly in proportion to ensure complete curing. In actual work, the viscosity of glue A and gl...
