Problems solved by technology

[0003] Most of the environmentally friendly tapes on the market are designed from the perspective of low VOC, using non-woven fabric substrates and low VOC adhesives to reduce their environmental pollution. On the one hand, the existing environmentally friendly tape products do not have special sterilization Design, on the other hand, due to the existing environmentally friendly adhesive tapes emphasize environmental affinity and appropriately reduce the adhesive performance of the adhesive as a sizing material, resulting in a decline in the adhesive performance of the adhesive tape itself relative to other adhesive tapes, although it can greatly reduce the impact on the environment. pollution, but it is easy to reduce the adhesive performance of the tape due to the glue components and the thickness of the tape

preparation example Construction

[0038]In the present invention, the preparation method of the bactericidal layer comprises the following steps:

[0039] 1) First mix nano-scale titanium dioxide, nano-scale aluminum oxide, nano-scale boron oxide, nano-scale silicon dioxide, and deionized water according to the formula amount, then stir at 800-1000rpm for 34-45min, and stir evenly Standby, obtain standby mixture 1;

[0040] 2) Stir the polyacrylate emulsion and propylene glycol in the formula amount for 10-20min at 400-600rpm, stir evenly for later use, and obtain the standby mixture 2;

[0041] 3) Then, mix the standby mixture 1 and standby mixture 2, and add a defoamer and stir at 600-800rpm for 10-20min;

[0042] 4) Then, while the stirring speed is constant, add cellulose and nano-scale calcium carbonate in the formula and stir for 8 minutes;

[0043] 5) Finally, add the thickener in the prescribed amount, and stir at 400-600rpm for 10-20min to prepare the bactericidal layer.

[0044] The bactericidal l...

Abstract

The invention discloses a low-VOC environment-friendly sterilizing adhesive tape which comprises a base material layer, sterilizing layers, low-VOC adhesive layers and a release type layer, wherein the base material layer is of a double-layer compound structure and comprises a nonwoven fabric layer and a PET membrane layer; the sterilizing layers are respectively covered to the upper surface and the lower surface of the base material layer to form a first sterilizing layer and a second sterilizing layer; the low-VOC adhesive layers are respectively adhered to the other surface of the first sterilizing layer and the other surface of the second sterilizing layer to form a first low-VOC adhesive layer and a second low-VOC adhesive layer; the release type layer is adhered to the other surfaceof the second low-VOC adhesive layer. By means of the compound base material layer, the adhesive tape disclosed by the invention has certain softness and excellent fit and further has certain strength; by means of the design of the sterilizing layers, the adhesive tape not only has a function of inhibiting bacteria and virus breeding, but also has functions of adsorbing VOC gas and decomposing organic pollutant; by means of the low-VOC adhesive layers, VOC organic pollutants are greatly reduced.

Description

technical field [0001] The invention relates to the field of environment-friendly tapes, more specifically, to a low-VOC environment-friendly sterilization tape. Background technique [0002] With the rapid development of industry, the existing adhesive tapes on the market have met some of people's needs to a certain extent, but environmental problems have become more and more prominent in recent years. And more and more environmentally friendly tapes are used in automotive electronic components systems in aviation, aerospace and other fields. [0003] Most of the environmentally friendly tapes on the market are designed from the perspective of low VOC, using non-woven fabric substrates and low VOC adhesives to reduce their environmental pollution. On the one hand, the existing environmentally friendly tape products do not have special sterilization Design, on the other hand, due to the existing environmentally friendly adhesive tapes emphasize environmental affinity and ap...
