Embodiment 1

[0028] A louver blade coating provided by the invention includes: coating on the woven fabric blade, including an inner coating film and an outer coating film; the formula of the inner coating film contains modified polyvinyl acetate polymer Stiffening agent and water of polymer, wherein the percentage by weight of stiffening agent is 20%; In the prescription of described outer coating film, comprise waterproofing agent, nanometer titanium dioxide and water, wherein the weight percent of organic fluororesin C6 waterproofing agent, nanometer titanium dioxide are respectively 3% and 0.3%.

Embodiment 2

[0030] A louver blade coating provided by the invention includes: coating on the woven fabric blade, including an inner coating film and an outer coating film; the formula of the inner coating film contains modified polyvinyl acetate polymer Stiffening agent and water of polymer, wherein the percentage by weight of stiffening agent is 30%; In the formula of described outer coating film, comprise waterproofing agent, nanometer titanium dioxide and water, wherein the weight percent of organic fluororesin C6 waterproofing agent, nanometer titanium dioxide are respectively 8% and 0.8%.

Embodiment 3

[0032] like figure 1 , figure 2 Shown; The present invention also provides a kind of preparation method of louver blade coating, comprises the following steps:

[0033] 1) Mix the stiffening agent and water according to the ratio to form the inner coating film mixture;

[0034] 2) The louver blades are dipped, and the inner coating film mixture is evenly coated on the surface of the blades and the inside of the weaving gap; then baked at 60-℃ for 3 minutes to form a hardened inner coating film;

[0035] 3) Mix waterproofing agent, nano-titanium dioxide and water in proportion to form an outer coating film mixture;

[0036] 4) Dip the louver blades with the hardened inner coating film to evenly coat the coating on the surface of the protective film; then bake at 60°C for 3 minutes to form a hardened outer coating film.

[0037] The baking in step 2) and step 4) is carried out in a baking device. The baking device includes a long box 1, and the box includes an inverted bucket-...

Abstract

The invention provides a louver leaf coating which coats woven fabric leaves and comprises an inner coating and an outer coating. The inner coating is composed of a stiffening agent and a first solvent, weight percent of the stiffening agent is 20-30%, the outer coating is composed of a waterproof agent, nano titanium dioxide and a second solvent, and weight percents of the waterproof agent and nano titanium dioxide are 3-8% and 0.3-0.8% respectively. By improving proportion of the stiffening agent and the first solvent, bending resistance of the textile leaf coating is improved; on the basisof improving bending resistance of the inner coating, the outer coating is sprayed on the outer surface of the inner coating, so that waterproof performance of textile leaves is further improved; by adding nano titanium dioxide into the outer coating, formaldehyde and harmful substances VOCS in surrounding air can be absorbed.

Description

technical field [0001] The invention relates to the field of louver blade manufacturing, in particular to a louver blade coating and a preparation method thereof. Background technique [0002] At present, shutters are curtains hung on windows with functions of shading, heat insulation and ventilation. Existing shutters generally consist of multiple blades strung together by ropes. Existing textile blades on the market are usually made by using solid acrylic hard-repellant and fluorine-based waterproof finishing. Although they have a certain hard-repellent effect and waterproof function, they have single functions and poor bending resistance. However, in the process of assembly and use, if the blade is slightly bent or touched by hard objects, scratches and marks will be left. The elasticity of the leaves is poor; it will affect the appearance after a period of use. [0003] In the prior art, just like the patent document 1: CN201620061120.7, this invention patent provides...
