Rustproof air nail hole sealing rubber and preparation method thereof

Abstract

The invention discloses rustproof air nail hole sealing rubber and a preparation method thereof and belongs to the technical field of metal rust prevention. According to key points of the technical scheme, the rustproof air nail hole sealing rubber is prepared from the following raw materials in parts by weight: 20-40 parts of a solvent, 5-20 parts of a rust remover, 20-40 parts of resin and 1-5 parts of a rheology modifier. The invention also discloses a preparation method of the rustproof air nail hole sealing rubber. The preparation method of the rustproof air nail hole sealing rubber has the advantages that a small amount of environment-friendly and non-toxic solvent and modified polymer resin are used as main raw materials, and the product has strong filling performance on air nail holes and good bonding performance with wood and air nails, so that the rustproof air nail hole sealing rubber hardly falls off or cracks after filling; and the used modified polymer resin has strong weather resistance and water resistance, so that filling materials in the air nail holes hardly expand with heat and contract with cold to generate deformation after repairing and are moistureproof.

Description

technical field [0001] The invention belongs to the technical field of metal antirust, and in particular relates to an antirust air nail hole sealing glue and a preparation method thereof. Background technique [0002] Woodenware manufacturing is a traditional handicraft manufacturing industry. With the progress of the times, woodware manufacturing has become more and more sophisticated and complex. Modern woodware manufacturing is more pursuing the fast processing process and the environmental protection and health of product materials. There are generally two methods in the process of processing, assembling and splicing woodware: one is to splice through mortise and tenon and then bond with adhesive. Tenon-tenon joints generally require a relatively large area to be modified, and a large amount of adhesive needs to be applied. The curing of the adhesive and the volatilization of the solvent take a long time, and the harmful gas generated will endanger human health. The cu...

Problems solved by technology

After solidification, the putty has a high hardness and a brittle material, which requires a large number of workers to polish, and may damage the surrounding wood during polishing; in addition, the putty uses inorganic powder as a filler, so it is difficult to color, and there will be color difference with the surrounding wood. ;Use volatile organic solvents to reconcile the putty, the consolidation speed is very fast, but the putty is easy to deform or fall off after consolidation; other methods include 502 glue, wood water ash, etc. The repair materials will also fall off, Problems such as cracks and bulges at repaired places, the effect is not ideal

[0004] To sum up, although there are many methods for the assembly and splicing process in woodware manufacturing, they are still not perfect, and there are situations where organic compounds that are not conducive to human health volatilize or affect the appearance, and the service life of various methods cannot be guaranteed.
