Abstract

The invention relates to the technical field of chemical materials, in particular to environment-friendly elastic putty and a preparation method thereof.According to the environment-friendly elastic putty, polyether polyol resin and asparaginic acid resin are synergistically compounded, system crosslinking is increased by adding a nanometer reinforcing material, an MDI curing agent and an HDI polyisocyanate curing agent are compounded, and the environment-friendly elastic putty is prepared. The environment-friendly elastic putty is obtained by using an environment-friendly and safe organic bismuth catalyst and adding appropriate pigments and fillers, the putty does not contain toxic organic tin components, the adhesive force of the putty on a blade base material can reach 10 MPa or above, and the impact resistance is gt; the thickness is 100 cm, and the bending resistance is 1t; the putty has the advantages that the thickness is 1 mm, the solid content is 99% or above, the construction time is as long as 8 hours or above, the curing time can be flexibly adjusted by utilizing the catalyst, the polishing is convenient and quick, the construction efficiency is high, and the use requirement of the fan blade putty is met.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to an environment-friendly elastic putty and a preparation method thereof. Background technique [0002] After the fan blade is taken out from the forming mold, there will be defects in the local area of ​​the surface. In addition, there are also gaps in the joint after the two blades are bonded. Therefore, it is usually necessary to use putty to repair the uneven surface of the blade, small holes and large seams. , after grinding, the next coating process can be carried out. Fan blades will not only be impacted by wind, sand, rain and other impacts during operation, but also undergo certain deformation. Therefore, the coating system including putty is required not only to have excellent adhesion, but also to have high flexibility and mechanical strength. Ordinary epoxy putty, unsaturated polyester putty, and solvent-based polyurethane putty are difficult to take into ac...
