A kind of dinosaur fossil anti-weathering material and preparation method thereof

It is a anti-weathering and anti-fossil technology, which is applied in the direction of anti-corrosion coatings and coatings. It can solve the problems of temperature resistance, weather resistance (poor aging resistance, poor solvent resistance of nitro paint, poor yellowing resistance, etc.), and achieves low cost and additional cost. Strong force and good thermal stability

Problems solved by technology

However, nitro paint has poor solvent resistance, poor temperature resistance, weather resistance (aging resistance), and poor yellowing resistance. If nitro paint is stored for a long time, it will easily turn yellow and red.
Epoxy resin has strong adhesion, low shrinkage, good reinforcement, stable size and good mildew resistance, but its preparation cost is high, and when using certain resins and curing agents, it is more toxic and has poor air permeability. Easy to change color under ultraviolet radiation

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0030] A weatherproof material for dinosaur fossils, which is composed of methyl triethoxy silicone resin ethanol emulsion and modified nano silicon dioxide.

[0031] Its preparation method is as follows:

[0032] 1. The preparation method of methyl triethoxy silicone resin ethanol emulsion: industrial grade MeSi (OEt) 3 and saturated Na 2 CO3 The aqueous solution is added into a glass reactor with a volume ratio of 100:(1-2), heated and distilled to refine, remove low boilers, and collect fractions with a boiling range of 140-145°C to obtain refined MeSi(OEt) 3 (HCl content below 2 μL). In terms of parts by mass, add 100 parts into a glass reactor with a stirring and reflux condenser, then add 60 parts of dilute hydrochloric acid containing HCl / L of 153 μL / L, carry out back distillation at 80°C for 3 hours, and then add 0.025 Part Me 3 SiNHSiMe 3...

Abstract

The invention discloses a dinosaur fossil anti-weathering material and a preparation method thereof. The method comprises the steps that a methyltriethoxy organic silicon resin ethanol emulsion with the mass concentration ranging from 30% to 50% is prepared; octamethylcyclotetrasiloxane modified nano-silicon dioxide and a dispersing agent special for nano-silicon dioxide are added, ultrasonic treatment is conducted, and a methyltriethoxy organic silicon resin composite emulsion doped with modified nano-silicon dioxide, namely, the dinosaur fossil anti-weathering material is obtained. The dinosaur fossil anti-weathering material is waterborne composite paint which is convenient to construct, low in cost, poisonless and environmentally friendly and has the advantages of being good in chemical stability and film-forming property; the formed film has the advantages of being good in acid and alkali corrosion resistance and ultraviolet aging resistance, high in adhesion, good in thermal stability, good in light transmission and the like, can maintain the original appearance of a dinosaur fossil, better improve the anti-weathering capacity of the dinosaur fossil and prolong the life of the dinosaur fossil and can have a good fixing effect on surrounding rocks on the periphery of the dinosaur fossil.

Description

technical field [0001] The invention relates to a protective material for dinosaur fossils, in particular to a dinosaur fossil anti-weathering material and a preparation method thereof. Background technique [0002] Dinosaur fossils are after the death of dinosaurs, the soft tissues in the body disappeared due to decay, and the hard tissues such as bones (including teeth) were deposited in the sand, in an oxygen-isolated environment, after tens of millions or even hundreds of millions of years of deposition , the bone is fully mineralized and preserved. Zhucheng, Shandong has a wide variety of dinosaur species, a wide range, and rich burials. It is a rare treasure house of dinosaur fossils in the country, so it has the reputation of "the hometown of dinosaurs". Dinosaur fossils are precious treasures left by nature to human beings to allow future generations to understand the laws of biology and their own evolution. They are organisms preserved in rocks. They have very impo...
