Problems solved by technology

[0002] At present, the traditional production process of adhesives is through three stages of dispersion, vacuum defoaming and filling in a vacuum mixer. The disadvantages are long production time, low production efficiency and insufficient fineness.
Moreover, the traditional production uses a vacuum disperser with only one motor, which is time-consuming and low in production efficiency.

Embodiment 1

[0024] Step 1, high-speed dispersion: first add epoxy resin E42 with a mass part ratio of 40 parts into the first material tank of the high-viscosity vacuum mixer. The high-viscosity vacuum mixer is equipped with a heating jacket, and the stirring motor is started. At a temperature of 40°C, stir at a speed of 300 rpm. While stirring, start the scraping motor to start the scraping parts, and then add epoxy resin CY with a mass ratio of 4 parts in sequence while stirring. -183, 1 part of silane coupling agent, 15 parts of quartz powder, 20 parts of precipitated barium sulfate and 0.2 part of fumed silica, after adding all the materials, stir for 0.5h.

[0025] Step 2, high-pressure extrusion: Take out the first material cylinder from the vacuum mixer described in step 1, then put the first material cylinder into a high-viscosity hydraulic extruder, and under the condition of a pressure of 12MPa, the hydraulic cylinder The piston rod is moved downward under the action, and the mi...

Embodiment 2

[0030] Step 1, high-speed dispersion: first add the mixture of epoxy resin E44 and epoxy resin E51 with a mass part ratio of 60 parts into the first material tank of the high-viscosity vacuum mixer. The high-viscosity vacuum mixer has a heating clamp set, start the stirring motor to stir, and stir at a temperature of 60°C at a speed of 1000 rpm. While stirring, start the scraping motor to start the scraping parts, and then add mass parts in sequence while stirring. The ratio is 10 parts of epoxy resin CY-184, 5 parts of silane coupling agent, 30 parts of quartz powder, 35 parts of precipitated barium sulfate and 0.5 part of fumed silica. After all materials are added, stir for 0.5 h.

[0031] Step 2, high-pressure extrusion: Take out the first material cylinder from the vacuum mixer described in step 1, then put the first material cylinder into a high-viscosity hydraulic extruder, and under the condition of a pressure of 16MPa, in the hydraulic cylinder The piston rod is move...

Embodiment 3

[0036] Step 1, high-speed dispersion: first add the mixture of epoxy resin E42 and epoxy resin E51 with a mass part ratio of 50 parts into the first material tank of the high-viscosity vacuum mixer. The high-viscosity vacuum mixer has a heating clamp set, start the stirring motor to stir, and stir at a temperature of 50°C at a speed of 700 rpm. While stirring, start the scraping motor to start the scraping parts, and then add mass parts in sequence while stirring. The ratio is 7 parts of epoxy resin CY-184 and epoxy resin CY-183 mixture, 3 parts of silane coupling agent, 22 parts of quartz powder, 27 parts of precipitated barium sulfate and 0.4 parts of fumed silica, After all the materials were added, it was stirred for another 0.5h.

[0037] Step 2, high-pressure extrusion: Take out the first material cylinder from the vacuum mixer described in step 1, then put the first material cylinder into a high-viscosity hydraulic extruder, and under the condition of a pressure of 14MP...

Abstract

The invention discloses an adhesive production process method. The adhesive production process method comprises the following steps: carrying out high-speed dispersion, namely putting a mixture in a first material cylinder of a vacuum mixer so as to mix the mixture; carrying out high-pressure extrusion, namely taking out the first material cylinder from the first material cylinder, and putting the first material cylinder in an extruding machine, extruding the mixture obtained by mixing from the first material cylinder, and enabling the extruded mixture to enter a grinding machine through a feeding port of a grinding machine; grinding the mixture entering the grinding machine, enabling the ground mixture to enter a second material cylinder from a discharging port of the grinding machine, after completely extruding the mixture obtained by the mixing from the first material cylinder and ending grinding, enabling the ground mixture to enter the second material cylinder for later use; putting the second material cylinder in the vacuum mixer so as to carry out vacuum defoaming; and extruding out the mixture subjected to the vacuum defoaming by using the extruding machine and filling. The adhesive production process method has the advantages that the production time is shortened, the product quality is improved, and the prepared adhesive is thorough in defoaming and has high fineness.

Description

technical field [0001] The invention relates to an adhesive, in particular to a production process of the adhesive. Background technique [0002] At present, the traditional production process of adhesives is through three stages of dispersion, vacuum defoaming and filling in a vacuum mixer. The disadvantages are long production time, low production efficiency and insufficient fineness. Moreover, the traditional production uses a vacuum dispersing machine with only one motor, which is time-consuming and low in production efficiency. Contents of the invention [0003] In order to solve the deficiencies of the traditional adhesive production process, the object of the present invention is to provide a production process for the adhesive. Through the production process, the production time is shortened and the product quality is improved. Advanced adhesive, complete defoaming, high fineness, higher quality. [0004] The technical scheme provided by the invention is: [000...
