High-flame-retardancy pressure-sensitive adhesive and manufacturing process thereof

Abstract

The invention discloses a high-flame-retardancy pressure-sensitive adhesive and a manufacturing process thereof. The high-flame-retardancy pressure-sensitive adhesive comprises the following components in parts by weight: 80 parts of mineral oil; 15 parts of an antioxidant; 40 parts of a flame retardant; 50 parts of a petroleum resin tackifier; 200 parts of a styrene copolymer; the preparation method comprises the following steps: (1) putting the mineral oil, the antioxidant and the flame retardant into mixing equipment, and stirring for 30-40 minutes in a shearing manner to mix the mineral oil, the antioxidant and the flame retardant, so that the antioxidant and the flame retardant are blended into the mineral oil; (2) dropwise adding the petroleum resin tackifier into the mixing equipment until the petroleum resin is blended into the mineral oil, and tackifying the solution; and (3) uniformly dripping the styrene copolymer into the mixing equipment. The high-temperature flame-retardant pressure-sensitive adhesive has the characteristics of high-temperature flame-retardant effect and high use safety, can continuously scrape off materials on the inner wall of the inner container during actual use, ensures heat exchange of the materials, can perform shearing and stirring, realizes sufficient mixing of the materials, improves the stirring efficiency, shortens the preparation period, and ensures the quality of the pressure-sensitive adhesive.

Description

technical field [0001] The invention relates to the technical field of pressure-sensitive adhesives, in particular to a highly flame-retardant pressure-sensitive adhesive and a manufacturing process thereof. Background technique [0002] The full name of pressure-sensitive adhesive is pressure-sensitive adhesive, also commonly known as self-adhesive, referred to as pressure-sensitive adhesive. Pressure-sensitive adhesive products include three categories: pressure-sensitive adhesive tape, pressure-sensitive adhesive label paper, and pressure-sensitive film. Depending on the application occasion, additives can be added to the pressure-sensitive adhesive to modify it to meet the application requirements; [0003] During the preparation process of the pressure-sensitive adhesive, it must be stirred to ensure uniform mixing and improve the mixing efficiency. However, due to the high viscosity of the pressure-sensitive adhesive, it is easy to stick to the inner wall of the mixer...
