Low-VOC environment-friendly sterilizing adhesive tape
PendingCN108441131AWith softnessImprove fitFilm/foil adhesivesEster polymer adhesivesAdhesiveCompound structure
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.

Pressure sensitive adhesive with high stripping force and preparation method thereof
ActiveCN110041860AImprove peel forceGood initial adhesionEster polymer adhesivesRosin adhesivesIsooctyl acrylate1-dodecanethiol
The invention discloses a pressure sensitive adhesive with the high stripping force. The pressure sensitive adhesive is prepared from the following raw materials, in parts by weight: 45-55 parts of 2-ethylhexyl acrylate, 4-9 parts of acrylamide, 40-50 parts of butyl acrylate, 7-12 parts of hydroxypropyl acrylate, 3-7 parts of methyl acrylate, 70-90 parts of ethyl acetate and butanone with the massratio being 1 to 1, 1.3-2.2 parts of azodiisobutyronitrile, 0.6-1 part of 1-dodecanethiol and 3-5 parts of tuluene diisocynate. The pressure sensitive adhesive with the high stripping force has the good initial adhesion and persistent adhesion, the 180-degree stripping force is high and can be held at the temperature of 90 DEG C, and the pressure sensitive adhesive can adhere firmly, and has thegood anti-plasticizer property and temperature resistance. No benzene and methylbenzene serves as solvents in the synthesis process of the pressure sensitive adhesive, and the pressure sensitive adhesion is low in toxicity, environmentally friendly, and wide in application range.
