Detailed Description
For a thorough understanding of the present invention, the present invention will be described in detail with reference to the following specific examples, and the accompanying drawings. The objects, features and effects of the present invention will be apparent to those skilled in the art from the disclosure of the present specification. It is to be understood that the invention may be practiced or carried out in other embodiments and that various modifications and alterations may be made in the details of the description herein without departing from the spirit or scope of the invention. The drawings of the present invention are merely schematic illustrations, and are not drawn to actual dimensions. The following embodiments will further illustrate the related art content of the present invention in detail, but the disclosure is not intended to limit the claims of the present invention. The description is as follows:
the high-temperature-resistant anti-leakage glue provided by the embodiment of the invention is mainly used for the surface coating of the fastener so as to improve the locking anti-leakage capacity of the fastener. The high-temperature-resistant leak-proof adhesive comprises the following components: 20 to 30 parts by weight of a resin, 10 to 15 parts by weight of a carbonate and 15 to 25 parts by weight of graphite.
The resin is preferably an acrylic resin (acrylic resin), which is a generic term for polymers of acrylic acid, methacrylic acid and derivatives thereof, which is a main body of the high temperature resistant leakage preventing glue, mainly imparting compression elastic ability to the glue. When the colloid is coated on the surface of the fastener, the high-temperature-resistant anti-leakage colloid taking the acrylic resin as a main body can be compressed to fill gaps, so that the anti-leakage function is achieved.
Carbonate refers to carbonate-containing salts such as sodium carbonate or calcium carbonate. In this example, calcium carbonate (CaCO) is used 3 ) Also known as limestone or limestone, can promote the connection of colloid and fastenerThe bonding function of the joint and the shearing force resistance.
Graphite (Carbon) has high temperature resistance and high strength properties, thus providing colloid temperature resistance.
With reference to fig. 1, the following will describe a method for preparing the high temperature resistant and leakage resistant glue of the present invention.
As shown in fig. 1, in step S101, a resin (preferably, an acrylic resin) is first dispersed by adding a water-soluble dispersant, and diluted. In this example, 20 to 30 parts by weight of water was added to disperse, dilute the acrylic resin, and stirred to mix well. However, the present invention is not limited thereto, and the ratio of water may be adjusted, or other water-soluble solvents may be used as the dispersing agent, the diluent.
In step S102, a carbonate (preferably calcium carbonate) is added as an auxiliary material. The calcium carbonate has adhesiveness when meeting water, and can increase adhesiveness of colloid.
Finally, in step S103, graphite is added. Graphite has porosity and is a high temperature resistant material. When graphite is added, other components enter the pores of the graphite structure and are protected at high temperatures.
Further, the preparation method of the high-temperature-resistant leak-proof adhesive can further comprise the following steps: in step S104, the glue formed by mixing is coated on the seat surface of the fastener, and in step S105, the fastener is baked at a temperature of 70 ℃ to 90 ℃.
The fastener of the present invention having the aforementioned high temperature resistant leakage preventing glue will be described next.
As shown in fig. 2, the fastener 100 with high temperature resistant and glue leakage preventing of the present embodiment includes: head 1, screw rod portion 2 and high temperature resistant leak protection glue 3.
The head 1 has a diameter slightly larger than that of the screw portion 2, and when the fastener 100 with the high-temperature-resistant leakage-proof glue is locked to an object, the head 1 is exposed to the object.
The surface of the screw part 2 is provided with a plurality of screw teeth 22, and the upper section 21 of the screw part 2 is connected to the head part 1. In this embodiment, the screw thread 22 is a self-tapping thread, so that the hole of the object is cut and extruded without the matched internal thread, thereby achieving the purpose of locking. However, the present invention is not limited thereto, and the screw thread 22 may be of other types.
The high temperature resistant leak-proof glue 3 prepared by the method is coated on the seat surface of the head part 1 in a surrounding way.
Next, it is explained how the fastener 100 with high temperature resistant glue leakage prevention of the present invention achieves leakage prevention after drilling.
As shown in fig. 3, at the initial stage of drilling, a motor (not shown) rotating at a high speed drives the fastener 100 having a high temperature resistant and glue leakage preventing property to contact the surface of the plate a and applies downward axial pressure. The screw portion 2 rubs against the surfaces of the plates a and B and generates a high temperature (600 ℃ to 900 ℃), the metal in the vicinity of the screw portion 2 rapidly softens, and the heated material extends upward along the taper of the screw portion 2.
As the motor continues to drive the fastener 100 with the high-temperature-resistant and glue-leakage-preventing material to drill down, the screw teeth of the screw part 2 are engaged with the plates a and B to fasten the plates a and B, and the fastener 100 with the high-temperature-resistant and glue-leakage-preventing material is driven to rotate at a high speed, so that the screw teeth of the screw part 2 are fused with the plates a and B, thereby fastening the plates a and B. Thus, the high temperature resistant glue is still not fused and abutted between the fastener 100 with the high temperature resistant glue and the plate A under the condition of high temperature generated by the rapid rotation friction, and is compressed to fill the gap, so as to achieve the anti-leakage effect.
The experimental results of the high temperature resistant leak-proof glue of the invention compared with other groups of glue are described below.
TABLE 1
Table 1 shows the composition of the high temperature resistant anti-leakage glue of the invention, the first control group and the second control group. Wherein the units of the numbers in the table are parts by weight.
After the drilling locking is carried out, the high-temperature-resistant anti-leakage adhesive can maintain stability and non-melting and non-breaking properties through the high temperature during drilling, and can resist the shearing force of the friction between the adhesive and the seat surface during locking of the fastener, so that the anti-leakage property is maintained.
In contrast, the graphite of the first control group has reduced weight and reduced high temperature resistance, and the formulation is crushed to lose leakage resistance due to colloid abnormality caused by high temperature when the drilling locking is performed.
On the other hand, the weight of the calcium carbonate of the second control group is reduced, so that the bonding function and the shearing force resistance are reduced, and the formula cannot bear the friction shearing force between the colloid and the seat surface during locking when the drilling locking is performed, so that the formula is brittle and deformed, cannot be attached to the seat surface, and also cannot prevent leakage.
The present invention has been disclosed in the foregoing in terms of preferred embodiments, however, it will be understood by those skilled in the art that the embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that all changes and substitutions equivalent to the described embodiments are intended to be included in the scope of the present invention. Accordingly, the scope of the invention is defined by the appended claims.
