Problems solved by technology

The main components of dinosaur fossils are calcite and apatite, so new protective materials are required to be neutral or weakly alkaline to prevent damage to fossils by protective materials; most of the protective materials used for dinosaur fossils are nitro varnishes, which are poisonous , poor environmental protection, and at the same time, the color gradually becom

Abstract

The invention discloses a novel protection material suitable for a dinosaur fossil and a preparation method of the novel protection material. The material is compounded from acrylic polymer and modified nanosilicon dioxide. According to the method, an emulsion polymerization manner is adopted, methyl methacrylate, butyl methacrylate, methyl acrylate and crylic acid are taken as main monomers for polymerization, a modified nano SiO2 solution is added before or after the polymerization reaction, and the mixture is stirred and blended uniformly. The preparation process is simple, the raw materials are easily available, the cost is low, the method is environmentally friendly, and the industrial production is easily implemented. The novel protection material has an excellent chemical stability, a film formed by the novel protection material has the advantages of excellent corrosion resistance, weather resistance, adhesiveness and heat stability, the original appearance of the fossil is kept, the efflorescence of the dinosaur fossil caused by the environment factor is avoided, and the service life of the fossil is prolonged.

Description

technical field [0001] The invention relates to a material for protecting dinosaur fossils, belonging to the field of materials. technical background [0002] Dinosaur fossils are non-renewable precious wealth bestowed by nature on human beings. China is the country with the richest resources of dinosaur fossils in the world. Rich dinosaur fossils have been found in more than 20 provinces (municipalities and autonomous regions). By the end of 2012, my country has approved the establishment of more than 20 dinosaur fossils and dinosaur footprint fossils. National Geoparks and World Geoparks with geological relics such as dinosaur egg fossils as the main protection objects. At the same time, there are also a large number of natural museums, geological museums and special dinosaur museums with a large number of dinosaur fossils. The development of new materials for the protection of dinosaur bone fossils and paleontological fossils has important scientific value and huge appli...
