Since the materials in the fuselage of civil aviation and military aircraft have strict flame retardant requirements and frequently vibrate during flight, the polyurethane protective tape for aviation needs to have not only excellent flame retardant property but also good adhesion to prevent loosening.
Disclosure of Invention
The invention aims to solve the technical problem of providing the polyurethane protective adhesive tape for aviation, which has good flame retardant property and adhesive force, can play a role in protecting floors and panels in an engine room and prevent water from corroding.
In order to solve the technical problems, the invention provides a polyurethane protective adhesive tape for aviation, which comprises a modified polyurethane substrate, a flame-retardant pressure-sensitive adhesive layer coated on the modified polyurethane substrate, and a release film attached on the flame-retardant pressure-sensitive adhesive layer;
the modified polyurethane base material is prepared from the following raw materials in parts by weight through an extrusion process: 65-80 parts of polyurethane elastomer, 15-30 parts of PEI and 0.5-2 parts of flame retardant;
the flame-retardant pressure-sensitive adhesive layer is prepared from the following raw materials in parts by weight: 100 parts of acrylic acid glue, 20-80 parts of organic solvent, 5-10 parts of melamine resin, 5-10 parts of curing agent and 1-3 parts of flame retardant;

The polyetherimide material (PEI) is a novel engineering plastic, has excellent mechanical properties, has the characteristics of high strength and high modulus, and has the properties of radiation resistance, corrosion resistance, high and low temperature resistance, dielectric property, insulating property and wear resistance. According to the invention, PEI is adopted to modify polyurethane, and the obtained modified polyurethane base material is very tough and wear-resistant, can resist puncture, tear, abrasion and erosion, can meet the requirements of an aviation polyurethane protective adhesive tape, and achieves the similar performance of a 3M 8657L polyurethane protective adhesive tape. Meanwhile, PEI is an excellent flame retardant material, inherent flame retardance and low smoke degree are achieved without adding any additive, the combustion grade is UL94-V-0 grade, PEI is adopted to modify polyurethane, and a small amount of flame retardant is matched to perform synergistic flame retardance, so that the flame retardant property of the modified polyurethane substrate can be greatly improved, and the flame retardant grade of UL94-V-0 is achieved.
In the invention, in order to improve the flame retardant property of the pressure-sensitive adhesive, the inventor introduces a reactive flame retardant monomer, namely glycerophosphoric acid dimethacrylate, into the synthesis of the acrylic glue, namely introduces a flame retardant phosphoric acid group into the acrylic glue, thereby endowing the pressure-sensitive adhesive with the flame retardant property; in addition, the monomer can also increase the adhesive force of the pressure-sensitive adhesive to base materials such as metal, glass and the like, and improve the adhesive strength. The acrylic acid glue synthesized by the invention has higher weight average molecular weight which reaches 130W-150W, not only meets the requirement of the adhesive tape on initial adhesion, but also has good cohesion, thereby ensuring the high temperature resistance of the adhesive layer.
