Problems solved by technology

[0004] (1) When the polyurethane glue is prepared manually, the polyurethane glue is usually filtered manually, and the artificial filtration speed is slow. After the filtration is completed, it is manually stirred. Manual stirring is time-consuming and laborious, thereby reducing the preparation efficiency of the polyurethane glue;
[0005] (2) When the existing polyurethane glue production equipment is preparing polyurethane glue, the polyurethane glue is usually filtered directly through the filter device, and after the filtration is completed, it is rotated or vibrated and stirred by the stirring device, while the existing polyurethane glue production equipment Insufficient stirring will easily lead to low fusion speed and fusion efficiency of polyurethane glue

Embodiment Construction

[0036] In order to make the technical means realized by the present invention, creative features, goals and effects easy to understand, the following combination Figure 1 to Figure 8 , to further elaborate the present invention.

[0037] A preparation process of polyurethane glue, the specific preparation process is as follows:

[0038]S1. Equipment inspection: check the equipment before using the polyurethane glue production equipment to make polyurethane glue;

[0039] S2. Gluing treatment: After the equipment inspection is completed, the polyurethane glue to be filtered is manually placed in the screening device 3, so that the screening device 3 performs screening processing on the polyurethane glue to be filtered;

[0040] S3. Stirring treatment, after the screening is completed, the filtered glue falls to the stirring device 4, so that the stirring device 4 performs stirring treatment on the filtered glue;

[0041] S4. Quality inspection and blanking: After the mixing ...

Abstract

The invention relates to a polyurethane glue preparation process. An adopted device comprises a workbench, a pressurizing device, a screening device and a stirring device, the pressurizing device is installed at the upper end of the workbench, a screening device is arranged at the lower end of the pressurizing device, the screening device is installed in the middle of the upper end of the workbench, and the stirring device is arranged on the inner side of the screening device. The invention provides the polyurethane glue preparation process. According to the invention, polyurethane glue can beprepared manually; firstly, polyurethane glue is manually filtered; manual filtering speed is low, after the filtering is completed, the stirring is performed; time-consuming and labor-consuming manual stirring, therefore, the preparation efficiency of the polyurethane glue is reduced; when the existing polyurethane glue preparation equipment is used for preparing the polyurethane glue, usually,polyurethane glue is directly filtered through a filtering device and then is rotated or vibrated and stirred through a stirring device after being filtered, and the problems that existing polyurethane glue manufacturing equipment is insufficient in stirring, the polyurethane glue fusion speed is low, and the fusion efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of glue preparation, in particular to a polyurethane glue preparation process. Background technique [0002] Polyurethane glue is a glue containing urethane and isocyanate groups in the molecular chain. Due to the strong polar isocyanate and urethane groups, it has high reactivity and can be cured at room temperature, so it is suitable for metal, rubber, glass, ceramics, etc. , plastic, wood, fabric, leather and other materials have excellent adhesive properties. The low temperature resistance of polyurethane is extremely excellent, and it is the best among the existing glues. Polyurethane glue has a simple process, can be cured at room temperature and heating, and has little influence on thermal stress when different materials are glued together, and is widely used in various fields. Polyurethane glue has poor water resistance and heat resistance. During the process of polyurethane glue, it needs to be fi...
