Abstract
The invention discloses a preparation method of modified polyacrylic resin. The preparation method comprises the following steps of preparing a solution A: uniformly mixing acrylic acid, methyl acrylate and manuka essential oil according to a volume ratio of 1: 10-15: 5-10, preparing a B1 solution from 18-25g / L of ammoniumpersulfate and 25-35g / L of chitosanhydrochloride, preparing 22-28g / L of lauryl sodiumsulfate which is marked as a B2 solution, uniformly mixing nano-silver, nano-titanium dioxide and n-butyl acrylate according to a weight ratio of (0.4-0.6): (0.2-0.3): (20-25) to obtain asolution C, adding 12-15 parts by volume of the solution C into a reaction kettle, adding 6-8 parts by volume of the solution A and 15-20 parts by volume of the solution B2, and uniformly mixing, raising the temperature to 70 to 80 DEG C, stirring and dropwise adding 3-5 parts by volume of B1 solution, and heating to 80-85 DEG C, and keeping the temperature for 2-3 hours to obtain the modified polyacrylic resin. The invention further discloses the prepared modified polyacrylic resin. The modified polyacrylic resin is good in antibacterial property, high in elongation at break, high in tensilestrength and good in puncture resistance.
Description
technical field [0001] The invention belongs to the field of coatings, and in particular relates to a preparation method of a modified polyacrylic resin and the modified polyacrylic resin. Background technique [0002] Leather is denatured and non-perishable animal skin obtained through physical and chemical processing such as depilation and tanning. At present, the most used leather products are daily necessities such as leather shoes, leather clothes, and leather sofas. People often use leather coating to form a film on the leather surface to protect the fur. Polyacrylate emulsion has the characteristics of flexible and elastic film-forming, light resistance, aging resistance, and excellent wet rub resistance of the coating. It is a kind of leather textilecoating material widely used at present. However, traditional polyacrylate emulsion coatings are affected by environmental conditions during storage, transportation, and use, and mildew and bacterial growth often occur...
