Abstract
The invention discloses a preparation method of N-hydroxymethyl acrylamide composite water-based acrylic coating for wickerwork; relates to the technical field of artware, comprising: (1) preparing gel resin; (2) a castor oil-based compound; (3) mixing the raw materials; the paint prepared by the method has excellent adhesive force and impact resistance, the formed coating has better bonding performance with the surface of a wicker product by being painted on the surface of the wicker, the bonding force between the coating and the wicker product can be greatly improved through the promotion effect of the gel resin, and the adhesive force is greatly increased.
Description
Technical Field
The invention belongs to the technical field of artware, and particularly relates to a preparation method of an N-hydroxymethyl acrylamide composite water-based acrylic coating for wickerwork.
Background
Willow has strong adaptability to the environment, the growth of willow is all over the country, different regions breed different weaving cultures, and people can obtain inspiration from shading by straw hats woven by willow twigs to develop richer weaving skills. Willow is of many varieties and can be used for weaving, mainly: salix mongolica, salix integra, salix matsudana, salix caprea, salix saponaria, salix sagittaria, salix sinensissima and the like. The willow growth cycle is short, the willow can be grown into timber as a raw material in one year generally, the timber yield is high, the raw material supply is sufficient, the material taking is convenient, the willow weaving products are containers, artware and the like which are common in life of people at present, the willow weaving products are various in types, such as mats, baskets, dustpans, basketries, wicker boxes, shallow baskets, flower baskets, wicker fences, eating trays and the like, and through innovation and development, a plurality of decoration articles such as flowerpots, vases, lampshades and the like are formed and are deeply loved by people.
Disclosure of Invention
The invention aims to provide a preparation method of an N-methylolacrylamide composite water-based acrylic coating for wickerwork, which aims to overcome the defects in the prior art.
The technical scheme adopted by the invention is as follows:
a preparation method of an N-methylolacrylamide composite water-based acrylic coating for wickerwork comprises the following steps:
(1) preparing gel resin:
adding itaconic acid into a reaction kettle, introducing nitrogen into the reaction kettle, discharging air in the reaction kettle, adding a sodium hydroxide solution, stirring for reaction for 30min, adding N-methylolacrylamide, N-methylene-bisacrylamide and an initiator, heating to 30 ℃, stirring at the rotating speed of 500r/min for 2 hours, heating to 50-60 ℃, preserving heat for 10-12 hours, filtering, washing to neutrality, and drying to obtain gel resin;
(2) castor oil based compound:
dissolving ricinoleic acid into an organic solvent to obtain a ricinoleic acid solution, heating to 110-115 ℃, preserving heat for 15min, then adding ethylene glycol and nano zeolite powder, stirring for 15-20min, then adding a solid acid catalyst, continuing stirring for 2 h, then cooling to room temperature, adjusting the pH value of the system to be neutral, standing for 2 h, carrying out rotary evaporation under reduced pressure, and removing the solvent to obtain the ricinoleic acid solution;
(3) mixing raw materials:
sequentially adding the water-based acrylic resin, water and titanium dioxide into a stirrer, stirring at a high speed for 40min, then adding the castor oil-based compound and the gel resin, continuing to stir for 30-35min, then performing ultrasonic treatment for 10-15min, finally adding the defoaming agent and the wetting agent, and continuing to stir for 40min to obtain the water-based acrylic resin gel.
The molar ratio of the itaconic acid to the sodium hydroxide in the sodium hydroxide solution is 3:1.
The weight parts of the N-methylolacrylamide, the N, N-methylene bisacrylamide, the initiator and the itaconic acid are as follows: 3-5:1-1.6:0.8-0.9:50.
The initiator is ammonium persulfate.
The organic solvent is toluene;
the mass fraction of the ricinoleic acid solution is 20-25%.
The mixing molar ratio of ricinoleic acid to ethylene glycol in the ricinoleic acid solution is 1: 1;
the weight ratio of the glycol to the nano zeolite powder is 15: 1-2.
The solid acid catalyst is B2O3-Al2O3；

Aqueous coating materials also have disadvantages in use because their polymers have a high glass transition temperature (Tg), and a coating film is cracked during construction at normal temperature, which requires a reduction in film-forming temperature in order to form a uniform and continuous coating film. Therefore, the invention reduces the glass transition temperature of the polymer by preparing the castor oil-based compound, thereby reducing the film forming temperature, helping the emulsion polymer to form a film, further forming a uniform and continuous coating and greatly improving the comprehensive performance of the coating;
has the advantages that:
the paint prepared by the method has excellent adhesive force and impact resistance, the formed coating has better bonding performance with the surface of a wicker product by being painted on the surface of the wicker, the bonding force between the coating and the wicker product can be greatly improved through the promotion effect of the gel resin, and the adhesive force is greatly increased.
The paint prepared by the method has excellent aging resistance, the aging resistance of the surface of the coating formed after curing can be greatly improved through the synergistic promotion effect of the prepared gel resin and the castor oil-based compound, the service life of the surface coating of the wicker product can be further prolonged through obviously improving the aging resistance of the coating, and the service life of the wicker product is indirectly prolonged through reducing the use cost.
