Description

Technical Field

[0002] Servo motors can control speed and position with very accurate accuracy, and can convert voltage signals into torque and speed to drive the controlled object. The rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, it is used as an actuator and has the characteristics of small electromechanical time constant, high linearity, and starting voltage. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors. Its main characteristics are that there is no self-rotation when the signal voltage is zero, and the speed decreases at a uniform speed as the torque increases. At present, the front cover of the servo motor is usually directly rigidly connected to the fixed seat.

Therefore, by providing the water-resistant inner sheath 18 on the inner side of the metal composite belt 19, the interior of the shock-absorbing layer 12 can be prevented from being penetrated by water, thereby reducing the probability of the interior of the shock-absorbing layer 12 being penetrated by water, and then by filling the interior of the water-resistant inner sheath 18 with cable paste, the prevention of water intrusion is further strengthened.

[0048] The present embodiment describes a servo motor installation damping mechanism, wherein the outer wall of the shell of the servo motor body is coated with a continuous cool fabric. Since the shell of the servo motor body is basically a metal shell, the shell of the servo motor body is relatively hot after long-term operation or exposure to direct sunlight, which is inconvenient for operators to carry, assemble or disassemble. By coating the outer wall with the continuous cool fabric, not only the heat dissipation effect can be improved, but also the operator can operate the servo motor body conveniently, preventing the shell of the servo motor body from being hot and affecting the work, thereby improving work safety and convenience; the continuous cool fabric comprises a fabric base woven from cool polyester and a water-based polyurethane coating coated on the surface of the fabric base, and the cool polyester is composed of the following raw materials in parts by weight:

[0049]

[0050] The present invention uses cool polyester fibers doped with mica powder. The polyester fibers have the characteristics of being strong and durable, elastic, not easy to deform, corrosion-resistant, insulating, and crisp. At the same time, their low hygroscopicity will also make their moisture conductivity relatively less affected by mica powder. The present invention solves the problem of poor moisture conductivity of polyester fibers and no longer focuses solely on the properties of the fibers themselves, but on the fabric structure. In addition to the hygroscopicity of a single fiber, the moisture transfer efficiency between fibers can also affect the moisture conductivity of the fabric. This problem has not yet been paid attention to. The present invention coats a layer of water-based polyurethane coating on the surface of the fabric. The water-based polyurethane will form an efficient physical connection between the single polyester fibers, and moisture can diffuse through the polyurethane coating, thereby improving the moisture diffusion efficiency between the fibers.

[0051] The waterborne polyurethane coating coating treatment of the present invention is different from the hydrophilic finishing of general polyester fibers. Polyester has poor hygroscopicity but not poor moisture conductivity. The hydrophilic finishing of polyester refers to the bonding of the hydrophilic finishing agent with the polyester surface so that the surface has hydrophilic groups, which changes the dyne value of the polyester surface so that it is easily wetted by water, and then diffuses and evaporates in the polyester, thereby improving the moisture absorption and dehumidification performance. The waterborne polyurethane coating of the present invention also has the effect of modifying the polyester surface, and can also increase the moisture absorption rate of polyester fibers by the same mechanism, but from this mechanism, the degree of improvement is not as good as that of general silicone hydrophilic finishing agents. The more important role of the waterborne polyurethane coating of the present invention is to form a physical bridge between single fibers, so that moisture can cross between single fibers through the polyurethane coating, thereby greatly improving the moisture diffusion efficiency, that is, improving the moisture conductivity.

[0052] The mica powder has a flake diameter of 8-12 μm and a flake thickness of 0.5-1.5 μm.

[0053] The antioxidant is composed of antioxidant 1010 and antioxidant 168 in a weight ratio of 1:1.

[0054] Wherein, the ultraviolet absorber is one or more of salicylate absorbers, benzotriazole absorbers and hindered amine absorbers.

[0055] Wherein, the lubricant is one or more of zinc stearate, calcium stearate and talc.

[0056] The preparation method of the cool polyester is as follows: the raw materials constituting the cool polyester are mixed, fed into a screw extruder for melting, then ejected through the spinneret holes on a spinneret, air-cooled, and then subjected to a texturing process to obtain the cool polyester.

[0057] The method for making the above-mentioned continuous cool feeling fabric comprises the following steps:

[0058] (1) adding 100 parts by weight of polytetramethylene glycol, 40-50 parts by weight of toluene diisocyanate and 0.1-0.5 parts by weight of an organotin catalyst into a round-bottom flask, raising the temperature to 80-120° C. and maintaining the reaction for 3-4 hours to prepare a polyurethane prepolymer;

[0059] (2) adding 40-60 parts by weight of an organic solvent and 10-20 parts by weight of a hydrophilic chain extender to the polyurethane prepolymer, reacting at a temperature of 50-60° C. for 2-3 hours, and then adding 100 parts by weight of water and 1-2 parts by weight of a silane coupling agent to prepare a waterborne polyurethane coating;

[0060] (3) Weaving the cool polyester into a fabric base, dipping the fabric base into the waterborne polyurethane coating at a bath ratio of 1:10-12 for 30-60 minutes, taking out the cool polyester, and drying it in an oven at 60-80° C. to obtain the continuous cool fabric.

[0061] The properties of waterborne polyurethane coatings are quite diverse, and not all waterborne polyurethane coatings can meet the requirements of the present invention. To this end, the present invention provides a waterborne polyurethane coating and a method for applying the same to a fabric base, i.e., a method for making a continuously cool fabric. The waterborne polyurethane coating prepared by the above method of the present invention can not only improve the hydrophilicity of the fiber surface, but also fill the gaps between the fibers, effectively improve the water transfer efficiency between the fibers, thereby significantly improving the hygroscopicity of the polyester fiber, and solving the problem of poor hygroscopicity of the cool polyester.

[0062] Wherein, the organic tin catalyst is dibutyltin dilaurate.

[0063] The hydrophilic chain extender is composed of 1,4-butanediol-2-sodium sulfonate and trimethylolpropane polyethylene glycol monomethyl ether in a weight ratio of 1-2:1.

[0064] Wherein, the organic solvent is one of ethyl acetate, acetone, N-methylpyrrolidone and dimethylformamide, and the silane coupling agent is KH550.

[0065] The present invention uses cool polyester fibers doped with mica powder. The polyester fibers have the characteristics of being strong and durable, elastic, not easy to deform, corrosion-resistant, insulating, and crisp. At the same time, their low hygroscopicity will also make their moisture conductivity relatively less affected by mica powder. The present invention solves the problem of poor moisture conductivity of polyester fibers and no longer focuses solely on the properties of the fibers themselves, but on the fabric structure. In addition to the hygroscopicity of a single fiber, the moisture transfer efficiency between fibers can also affect the moisture conductivity of the fabric. This problem has not yet been paid attention to. The present invention coats a layer of water-based polyurethane coating on the surface of the fabric. The water-based polyurethane will form an efficient physical connection between the single polyester fibers, and moisture can diffuse through the polyurethane coating, thereby improving the moisture diffusion efficiency between the fibers.

[0087] (2) adding 40 parts by weight of an organic solvent and 10 parts by weight of a hydrophilic chain extender to the polyurethane prepolymer, reacting at a temperature of 50° C. for 3 hours, and then adding 100 parts by weight of water and 1 part by weight of a silane coupling agent to prepare a waterborne polyurethane coating;

[0088] (3) Weaving the cool polyester into a fabric base, immersing the fabric base in the waterborne polyurethane coating at a bath ratio of 1:10 for 30-60 minutes, taking out the cool polyester, and drying it in an oven at 60° C. to obtain the continuous cool fabric.

[0089] Example 3

[0090] The difference between this embodiment and embodiment 1 is that:

[0091] The method for making the above-mentioned continuous cool feeling fabric comprises the following steps:

[0092] (1) Add 100 parts by weight of polytetramethylene glycol, 50 parts by weight of toluene diisocyanate and 0.5 parts by weight of an organotin catalyst into a round-bottom flask, raise the temperature to 120° C. and keep reacting for 3 hours to prepare a polyurethane prepolymer;

[0093] (2) adding 60 parts by weight of an organic solvent and 20 parts by weight of a hydrophilic chain extender to the polyurethane prepolymer, reacting at 60° C. for 2 hours, and then adding 100 parts by weight of water and 2 parts by weight of a silane coupling agent to prepare a waterborne polyurethane coating;

[0094] (3) Weaving the cool polyester into a fabric base, dipping the fabric base into the waterborne polyurethane coating at a bath ratio of 1:12 for 60 minutes, taking out the cool polyester, and drying it in an oven at 80° C. to obtain the continuous cool fabric.

[0095] Comparative Example 1

[0096] The base fabric is the cool polyester woven fabric of Example 1 without surface treatment.

[0097] Comparative Example 2

[0098] The difference from Example 1 is:

[0099] The cool polyester fiber is conventionally finished with a silicone hydrophilic finishing agent and then woven into a fabric base without being subjected to a polyurethane coating treatment.

[0100] Comparative Example 3

[0101] The difference from Example 1 is:

[0102] The cool polyester fiber is impregnated with the water-based polyurethane coating in the same way, dried, and then woven into fabric.

[0103] Comparative Example 4

[0104] The difference from Example 1 is:

[0105] The fabric base is finished with a silicone hydrophilic finishing agent and is not coated with a polyurethane coating.

[0106] The thermal resistance and moisture resistance of the fabrics of Example 1 and Comparative Examples 1-3 were tested according to ISO11092:2004. The test results are shown in the following table:

[0107] <![CDATA[Thermal resistance (10 -3 k*m 2 *W -1 )]]> <![CDATA[Wet resistance (Pa*m 2 *W -1 )]]> Example 1 9.883 4.416 Comparative Example 1 9.117 5.557 Comparative Example 2 9.682 5.358 Comparative Example 3 10.152 5.424 Comparative Example 4 9.674 5.211

[0108] From the comparison in the above table, it can be seen that polyurethane coating or silicone hydrophilic finishing agent modification treatment of the fabric base will slightly affect the thermal conductivity of the fabric, while polyurethane coating of the fiber will significantly reduce the thermal conductivity. This is because the thermal conductivity of the polyurethane coating is not outstanding, and the impact will be more obvious when no bridging structure is formed between the fibers. Similarly, after the cool polyester fiber is coated with polyurethane, the improvement in moisture conductivity is not as good as that of the fabric treated with silicone hydrophilic finishing agent.
