Abstract

The invention discloses a high strength non-woven adhesive tape and a preparation method thereof. The non-woven adhesive tape is composed of the following raw materials in parts by weight: 40 to 60 parts of butadiene, 20 to 30 parts of styrene, 10 to 20 parts of polyester fiber, 10 to 30 parts of butyl acrylate, 10 to 20 parts of acrylic acid, 0.1 to 0.8 part of dibutyl phthalate, 2 to 8 parts of benzoyl peroxide, 5 to 10 parts of rosin, 1 to 10 parts of carboxylic acid, 2 to 6 parts of emulsifier, 0.1 to 1 part of dispersant, 0.05 to 0.15 part of stabilizing agent, 1 to 5 parts of reinforcing agent, and 100 parts of water. The properties of the non-woven latex are stable. The bonding force is strong. The thermal stability of the latex is stable. The color is not changed after 24 hours of reflux at a temperature of 50 DEG C. No gel is generated. The freeze-thaw stability is high. The non-woven adhesive tape is thawed after 50 days of freezing at a temperature of -20 DEG C, the color is not change, no gel is generated, and the requirements on production, storage, and transportation in different seasons can be met. The preparation method is simple. The non-woven adhesive tape prepared from the latex has the advantages of high tensile strength and high elongation at rupture and is resistant to cracking.

Description

technical field [0001] The invention belongs to the technical field of non-woven tapes, and in particular relates to a high-strength non-woven tape and a preparation method thereof. Background technique [0002] By adding latex and other auxiliary materials to the fibers, a strong and elastic non-woven tape can be obtained. At present, there are more than 500 kinds of non-woven tapes in the world, which are generally daily necessities and medical supplies, and are developing in the direction of "disposable". Therefore, the demand for non-woven latex is increasing. . Non-woven tape has many advantages, such as: strong ventilation performance; filtering performance; thermal insulation; strong water absorption; strong water performance; stretchability; not messy when used; non-woven tape feels good and soft; Lightweight; non-woven tape is elastic and recoverable; non-woven tape has no directionality of fabric; non-woven tape is inexpensive and mass-producible. At present, no...
