Problems solved by technology

The cross-section of rattan is covered with fine ducts, so rattan handicrafts are easy to absorb water, and once too much water is absorbed, the handicrafts will become soft and drooping, loose in structure, and prone to mildew and decay. Thereby seriously affecting the performance of rattan handicrafts

Embodiment 1

[0017] A kind of hydrophobic paint on the surface of rattan handicrafts is prepared through the following steps:

[0018] (1) Preparation of composite gel: Dissolve silicate in a polar solvent to obtain a silicate solution with a mass fraction of 10%, add ammonia water with a mass of 20% to the silicate solution, and stir evenly. Then uniformly disperse the aluminum powder into the silicate solution, the amount of aluminum powder added is 25% of the silicate mass, and then add a nitric acid solution with a mass fraction of 5%, wherein the molar ratio of nitric acid to aluminum powder is 1.5:1 , stirred at 85°C for 2 hours at a speed of 150r / min, then added modified starch, and continued to stir for 2 hours, wherein the amount of modified starch added was 15% of the mass of the silicate to obtain a composite gel;

[0019] (2) Hydrophobic modification: place the composite gel prepared in step (1) at 0°C for 1 hour, then rapidly raise the temperature to 90°C, add 1.5% simethicone...

Abstract

The invention discloses a rattan craft surface hydrophobic coating, and relates to the fields of processing of rattan crafts, wherein a method for preparing the coating includes the steps: (1) preparation of a composite gel; (2) hydrophobic modification; and (3) preparation of the coating. A hydrophobic microstructure of a coating film is built by preparing the composite gel; through modificationof the composite gel, the gel after modification forms a film and is cured in an organosilicone emulsion system, nanoparticles in the gel are gathered together in the film formation process, a microstructural mastoid is formed, hydroxyl groups of the coating film surface are combined with denatured starch, the hydroxyl groups of the coating film surface are greatly reduced, and the hydrophobicityof the coating film is improved remarkably.

Description

technical field [0001] The invention belongs to the field of treatment of rattan handicrafts, in particular to a hydrophobic coating on the surface of rattan handicrafts. Background technique [0002] Rattan is a natural healthy and environmentally friendly material. It is strong, light and flexible, and can be bent at will. The rattan handicrafts made of it have a simple and clear appearance, coexistence of rigidity and softness, and are popular among people. of favor. The cross-section of rattan is covered with fine ducts, so rattan handicrafts are easy to absorb water, and once too much water is absorbed, the handicrafts will become soft and drooping, loose in structure, and prone to mildew and decay. Thereby having had a strong impact on the performance of rattan crafts. Contents of the invention [0003] The purpose of the present invention is to provide a kind of hydrophobic coating on the surface of rattan crafts aiming at the existing problems. [0004] The pres...
