Problems solved by technology

The growth cycle of willow is short, usually it can be used as raw materials in one year, and the rate of finished products is extremely high, the supply of raw materials is sufficient, and it is convenient to obtain materials. Willow products are common containers and handicrafts in people's lives. Baskets, baskets, dustpans, buckets, wicker boxes, baskets, flower baskets, fences, food plates, etc., have been innovated and developed, and have formed flowerpots, vases, lampshades, and many other decorations, which are deeply loved by people. , but due to its wood properties, especially when the air is kept at high humidity for a long time, it will cause a large amount of mold to grow on the surface of the willow product, which will intensify the corrosion of the willow product, making it unusable

Abstract

The invention discloses a preparation method of an N-hydroxymethyl acrylamide composite water-based acrylic coating for wickerwork, and belongs to the field of artcraft. The preparation method comprises the following steps: (1) gel resin preparing; (2) a castor oil-based compound; (3) raw material mixing. The coating prepared through the method has excellent adhesive force and impact resistance, the coating is brushed on the surface of the wickerwork, the bonding performance of the formed coating and the surface of the wickerwork is better, the bonding force between the coating and the wickerwork can be greatly improved through the promotion effect of the gel resin, and the adhesive force is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of handicrafts, in particular to a preparation method of N-methylolacrylamide composite water-based acrylic paint for wicker. Background technique [0002] Willow is highly adaptable to the environment. It grows all over the country. Different regions breed different weaving cultures. People get inspiration from wicker straw hats for shade and develop richer weaving skills. There are many types of willows, and the ones that can be used for weaving mainly include: Salix salix, Chinese bark willow, dry willow, small red willow, soap willow, weeping willow, Artemisia willow, etc. The growth cycle of willow is short, usually it can be used as raw materials in one year, and the rate of finished products is extremely high, the supply of raw materials is sufficient, and it is convenient to obtain materials. Willow products are common containers and handicrafts in people's lives. Baskets, baskets, dustpans, buckets...
