Description

Technical Field

[0001] The invention relates to the technical field of electrical insulating tapes, in particular to a polyvinyl chloride electrostatic film tape. Background Art

[0002] Traditional polyvinyl chloride (PVC) tape has a wide range of applications in many fields, such as wire winding, insulation and fixation of electronic parts, etc. However, this material has some obvious defects. First, PVC tape is often difficult to peel off, which not only affects the convenience of use, but also may cause damage to the surface to which it is adhered. Secondly, the antistatic effect of PVC tape is not good, which is particularly problematic in the electronics industry because static electricity may damage sensitive electronic components. In addition, the storage stability of PVC tape is poor, and the insulation, heat resistance and antistatic properties are poor, which limits its application in electrical applications. In the packaging process of electronic products, although the existing antistatic tapes are widely used, they still have problems such as unsatisfactory antistatic performance, difficulty in tearing off, and environmental protection. Therefore, the development of a PVC electrostatic film adhesive that is easy to peel off and has good antistatic effect has become an important direction of technological development. This new material needs to overcome the shortcomings of traditional PVC tape and provide more superior insulation, heat resistance and antistatic properties to meet the higher requirements of modern industry for material properties.

[0010] Preferably, a polyvinyl chloride electrostatic film tape comprises the following steps:

[0011] Step 1, raw material preparation: weigh the raw materials in the formula ratio, including polyvinyl chloride, perchlorethylene resin, nano-scale fly ash, alkylamide phosphate betaine, hydroxysulfonpropyl betaine, carbon fiber, aluminum dihydrogen phosphate, lithium naphthenate and triallyl isocyanurate;

[0012] Step 2, mixing process: adding the weighed raw materials into a high-speed mixer and mixing;

[0013] Step 3: Extrusion granulation: feeding the uniformly mixed raw materials into a twin-screw extruder for extrusion granulation;

[0014] Step 4: Drying: The extruded particles are placed in an oven for drying;

[0015] Step 5, melt extrusion and calendering: melt-extrude the dried particles through an extruder, add a cross-linking agent and mix well, then spread them into a multi-layer film blowing machine and calender them into a film, cool them under natural conditions after film formation, and perform corona treatment;

[0016] Step 6: Pelletizing: The corona treated film is cut into tapes of desired shape and size by a pelletizer;

[0023] Compared with the prior art, the present invention provides a polyvinyl chloride electrostatic film tape, which has the following beneficial effects:

[0024] 1. The present invention can improve the comprehensive performance of the tape by selecting raw materials and adjusting the specific gravity range. Among them, the use of perchlorethylene resin can improve the antistatic performance of the tape, because it is not easy to burn and has stable chemical properties, which helps to reduce the generation and accumulation of static electricity, and nano-scale fly ash can reduce the adsorption between heavy metal particles on the surface of fly ash and fly ash, thereby improving the peel strength. The addition of carbon fiber can improve the adhesion performance of the tape, thereby increasing the peel strength, because the normal adhesion of carbon fiber composite materials on the silicon nitride surface is the highest. Betaine surfactants have good antistatic properties, washing foaming properties, thickening properties, hard water resistance, low irritation, conditioning properties, antibacterial properties and biodegradability. It is an amphoteric surfactant that can reduce the accumulation of static electricity. The above characteristics combined make the tape of the present invention perform well in antistatic performance and peel strength, and can be suitable for application scenarios requiring high antistatic performance and strong adhesion. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Figure 1 It is a flow chart of the steps of the present invention. DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1A polyvinyl chloride electrostatic film tape, the raw materials of the tape and their specific gravity range are: polyvinyl chloride 40% to 45%; perchloroethylene resin 11% to 14%; nano-level fly ash 12% to 16%; alkylamide phosphate betaine 2% to 5%; hydroxysulfonpropyl betaine 4% to 7%; carbon fiber 5% to 7%; aluminum dihydrogen phosphate 4% to 8%; lithium cyclohexane acid 3% to 6%; triallyl isocyanurate 1.52% to 1.94%.

[0028] Perchloroethylene resin: Perchloroethylene resin can improve the anti-static performance of the tape because it is non-flammable and chemically stable, which helps reduce the generation and accumulation of static electricity.

[0029] Nano-scale fly ash: Nano-scale fly ash can reduce the adsorption between heavy metal particles on the fly ash surface and the fly ash, thereby improving the peeling strength.

[0030] Carbon fiber: The adhesion performance of carbon fiber is affected by many physical properties such as the contact angle and roughness of the substrate. Among them, the normal adhesion of carbon fiber composite materials on the silicon nitride surface is the highest. Therefore, the addition of carbon fiber can improve the adhesion performance of the tape and thus increase the peel strength.

[0031] Betaine: Betaine surfactants have good antistatic properties, washing foaming properties, thickening properties, hard water resistance, low irritation, conditioning properties, antibacterial properties and biodegradability. Betaine is an amphoteric surfactant that can reduce the accumulation of static electricity.

[0032] Specifically, a polyvinyl chloride electrostatic film tape comprises the following steps:

[0033] Step 1, raw material preparation: weigh the raw materials in the formula ratio, including polyvinyl chloride, perchlorethylene resin, nano-scale fly ash, alkylamide phosphate betaine, hydroxysulfonpropyl betaine, carbon fiber, aluminum dihydrogen phosphate, lithium naphthenate and triallyl isocyanurate;

[0034] Step 2, mixing process: add the weighed raw materials into a high-speed mixer and mix (this step is to ensure that all ingredients are evenly distributed in the final product, thereby ensuring the performance consistency and reliability of the tape);

[0035] Step 3: Extrusion granulation: The uniformly mixed raw materials are fed into a twin-screw extruder for extrusion granulation (during the extrusion process, the temperature and pressure need to be strictly controlled to ensure that the material can be fully plasticized and form uniform particles);

[0036] Step 4: Drying: The extruded particles are placed in an oven for drying (to remove moisture and other volatile substances, which can improve the durability and stability of the tape);

[0037] Step 5, melt extrusion and calendering: melt-extrude the dried particles through an extruder, add a cross-linking agent and mix well, then spread them into a multi-layer film blowing machine and calender them into a film, cool them under natural conditions after film formation, and perform corona treatment (in the process of the multi-layer film blowing machine and the casting machine, the product is made in one time, which can improve production efficiency and product quality);

[0038] Step 6: Pelletizing: The corona treated film is cut into tapes of the required shape and size by a pelletizer (precise control to ensure the dimensional accuracy and surface quality of the tape);

[0039] Step 7: Post-processing: coating and printing the tape surface (to enhance its specific application performance).

[0040] Specifically, the setting conditions for mixing in step 2 are: the temperature is controlled at 36-42° C., and the mixing time is controlled at 16-20 min.

[0041] Specifically, when the mixing in step 2 is carried out to 2 / 3 of the total set time, an amide dispersion, an alcohol dispersion and triallyl isocyanurate are added in a weight ratio of 3:1:2 (to improve the dispersibility of the filler particles in the polymer and improve the stability and antistatic properties of the finished product).

[0042] Specifically, the extrusion conditions of step three are: the temperature is controlled at 220-230° C., the pressure is controlled at 1.5-3.0 MPa, and the particle size is controlled between 1.5-2.5 microns.

[0043] Specifically, triallyl isocyanurate is added during the melt extrusion process in step five (to increase the cross-linking degree of the material, thereby improving its heat resistance and mechanical properties).

[0044] Specifically, step five is corona treatment: corona treatment is performed for 3-5 minutes during the cooling and forming process of the film (so that the surface of the film is charged with static electricity during post-treatment to meet the needs of glue coating, which is beneficial to the combination of glue and film. The corona treatment does not increase the overall electrostatic function of the tape).

[0080] By comparing the raw material formulations of the adhesive tapes of the embodiments and comparative examples, the following information can be obtained:

[0081] Effect of perchlorethylene resin: Comparison of Example 1 with Comparative Example 1 shows that the addition of perchlorethylene resin (14%) can improve the peel strength of the tape, but reduce the elongation, heat resistance, antistatic effect, tensile strength, adhesion performance and thermal stability.

[0082] Comparison between polypropylene resin and perchlorethylene resin: Comparison between Example 2 and Comparative Example 2 shows that replacing perchlorethylene resin (13%) with polypropylene resin in Comparative Example 2 reduces peel strength and has an adverse effect on other properties.

[0083] Comparison of nano-scale fly ash and conventional particle size fly ash: Comparison of Example 3 with Comparative Example 3 shows that the use of nano-scale fly ash (13%) instead of conventional particle size fly ash in Example 3 can improve peel strength, elongation, heat resistance, antistatic effect, tensile strength, adhesion performance and thermal stability.

[0084] Effect of betaine type and ratio: Comparison of Example 4 with Comparative Example 4 shows that adjusting the ratio of alkylamide phosphate betaine and hydroxysulfonpropyl betaine can make the tape have an antistatic effect; among which, comparison of Example 6 with Comparative Example 6 shows that replacing other types of betaine with sulfonpropyl betaine will reduce the peel strength.

[0085] Effect of carbon fiber: Comparison of Example 5 with Comparative Example 5 shows that the addition of carbon fiber can improve the peel strength, elongation, heat resistance, antistatic effect, tensile strength, adhesion performance and thermal stability of the tape.

[0086] Effect of aluminum dihydrogen phosphate and lithium naphthenate: Comparison of the examples with the comparative examples shows that the addition of aluminum dihydrogen phosphate and lithium naphthenate helps to improve the heat resistance and thermal stability of the adhesive tape.

[0087] Effect of triallyl isocyanurate: Triallyl isocyanurate is used as a crosslinking agent, and the adjustment of its proportion will affect the mechanical properties and adhesion properties of the tape.

[0088] In summary, the performance of the tapes of the embodiments is generally better than that of the comparative examples, which indicates that the selection of raw materials and the specific gravity adjustment range of the present invention can improve the comprehensive performance of the tapes. Among them, the selection of types and proportions of perchlorethylene resin, nano-fly ash, carbon fiber and betaine can improve the antistatic performance of the tapes and increase the peel strength.
