Abstract

The invention relates to a medical adhesive tape and a preparation method thereof, and belongs to the technical field of high polymer materials. The medical adhesive tape provided by the invention comprises the following raw materials by weight: a component A including 10-20 parts of latex, 2-8 parts of methyl methacrylate, 1-2 parts of a defoaming agent, 0.5-1.0 part of a wetting agent and 10-20 parts of tap water; a component B including 20-30 parts of an organic silicone emulsion and 20-30 parts of tap water; a component C: 10-18 parts of benzoyl peroxide, 5-10 parts of glycerol ester of rosin and 80-100 parts of an acrylic pressure sensitive adhesive; and a component D including a certain amount of n-woven cloth and brown paper. The medical adhesive tape provided by the invention uses nonwoven fabric as the substrate for hospital adhesive tape to save a lot of cotton, and the adhesive prepared from acrylic pressure-sensitive adhesive, glycerol ester of rosin and benzoyl peroxide has good softness and paintability.

Description

technical field [0001] The invention relates to an adhesive tape and a preparation method thereof. More specifically, the invention relates to a medical adhesive tape and a preparation method thereof, belonging to the technical field of polymer materials. Background technique [0002] Traditionally, the base materials of medical tapes are basically made of cotton cloth. Due to the limited arable land available to humans, the large-scale cultivation of cotton is limited, which affects the supply of cotton cloth used as the base material of traditional medical tapes. In addition, pure cotton substrates also have disadvantages such as high cost and poor further processing performance. [0003] The State Intellectual Property Office published an invention patent with the publication number CN1152470 on June 25, 1997, named "Hot-melt Acrylate Medical Pressure-Sensitive Adhesive". The patent uses 60-90% butyl acrylate, 15-25% methyl Acrylic butyl acrylate and 3-5% acrylic acid a...
