Problems solved by technology

When using vinyl and cellulose acetate resins, it is difficult to use strong solvents such as ketones, chlorinated hydrocarbons, aromatic hydrocarbons, and a large amount of plasticizers such as dibutyl phthalate or dioctyl phthalate. Ensure that the protected object is not damaged
When using water-soluble substances such as microcrystalline cellulose and calcium salt of carboxymethylcellulose, or copolymer emulsions of acrylic resins, it is also easy to Problems such as water resistance and rust resistance occur

Abstract

The invention discloses a preparation method and a stripping method of a heat-resistant flame-retardant conductive peelable pressure-sensitive adhesive, and belongs to the technical field of adhesives. The thermoplastic elastomer hot-melt pressure-sensitive adhesive is prepared by blending and modifying the synthesized flame-retardant ferrocene organosiloxane and the polyester polyamide and supplementing with a dispersing agent, an anti-aging and the conductive flame retardant and the like, the quick and easy stripping of the pressure-sensitive adhesive is realized by adopting the ultravioletand electron beam stripping treatment and through the interaction of the components, and the flame-retardant effect can reach the V-0 grade. Meanwhile, the product also passes the European Union ROHSmechanism environment detection, and accords with the European Union ROHS standard. The adhesive has the advantages of simple preparation method, few added components, no solvent leveling agent or other assistants, low production cost, mild preparation conditions, environmental protection, small shrinkage and easy stripping effect.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a preparation method and a stripping method of a heat-resistant, flame-retardant, conductive and peelable pressure-sensitive adhesive. Background technique [0002] In order to protect mechanical precision parts, expensive electrical components, precious cultural relics and other parts or the surface of the whole machine from damage during transportation and storage, pressure-sensitive adhesives with short-term anti-rust and anti-pollution functions are called peelable pressure-sensitive adhesives. Adhesives and paint protectors. Among them, the adhered pressure-sensitive adhesive can be peeled off or easily peeled off when the product is used, which is called peelable pressure-sensitive adhesive. The peelable pressure-sensitive adhesive, which can be removed by a simple method or does not need to be removed, can play an irreplaceable role and have a great application prospect...
