Embodiment 1

[0045] Weigh 0.2g of sodium lauryl sulfate and add it to 74.77g of water. After mechanical stirring and mixing, add 10g of methyl methacrylate and 8g of divinylbenzene to the solution. After mechanical stirring, put Water bath in the pass N 2 After 15 minutes, after heating up to 75°C, dissolve 0.03g of potassium persulfate in 5g of water and add it to the above reaction mixture. After 2.5h of reaction, the reaction solution (i.e. latex core structure emulsion) is obtained, and slowly drip into the reaction solution Add a mixed solution of 1.5g butyl acrylate and 0.5g methacryloxypropyltrimethoxysilane, and finish adding dropwise within 0.5h. After continuing to react for 3 hours, the temperature was raised to 90° C. and kept for 30 minutes to obtain an anti-reflection coating liquid composed of latex particle solution Product 1 with a core-shell structure, with a solid content of 20%.

Embodiment 3

[0053] Weigh 1g of sodium alkyl sulfonate and add it to 68.95g of water, stir and mix evenly, add 10g of methyl methacrylate and 5g of divinylbenzene to the solution, stir evenly, put it into the water bath ZTO N 2 20min, after the temperature reaches 80°C, dissolve 0.05g of ammonium persulfate in 5g of water and add it to the above reaction mixture. After reacting for 3h, slowly add 8g of acrylonitrile and 2g of [4-(methacrylic Acyloxy) butyl] pentamethylsiloxane mixture, dropwise within 2h. After continuing the reaction for 3 hours, the temperature was raised to 90° C. and kept for 40 minutes to obtain an anti-reflection coating solution composed of latex particle solution product 3 with a core-shell structure, with a solid content of 25%.

[0054] Figure 5 It is the AFM photograph of the latex film of product 3. It can be seen that the surface of the coating film has a concave-convex nano-rough structure. Depend on image 3 with Figure 5 It can be seen that compared ...

Abstract

The invention discloses a coating liquid with latex particle reflection deducting capability as well as a preparation method and application of the coating liquid in a dacron fabric. The preparation method comprises the following steps: fully mixing an emulsifying agent with a part of water so as to form an emulsifying agent aqueous solution; adding a core-forming monomer and a cross-linking agent into the emulsifying agent aqueous solution, introducing protective gas so as to deoxidize for 15-20min; heating to 70-80 DEG C, adding the initiator and residual water, and reacting for 2-3 hours, so as to obtain a core-structure emulsion of latex; dropwise adding a first shell monomer and a second shell monomer into the core-structure emulsion of the latex for 1-1.5 hours; and after finishing dropwise adding, further reacting for 2-3 hours, and performing heat preservation at 85-90 DEG C for 30-45 minutes, there by obtaining the coating liquid with latex particle reflection deducting capability. The coating liquid can form a nano rough surface with low refractive index on the surface of the dacron fabric, so that reflection deduction and densification of dacron are realized, and furthermore, the structure is adhered to the fibers by virtue of shell layers and thus is endowed with a durable tidying effect.

Description

technical field [0001] The invention relates to the field of textile auxiliaries and its preparation, in particular to a latex particle anti-reflection coating liquid, its preparation method and its application on polyester fabrics. Background technique [0002] Polyester fabric has the advantages of wear resistance, stiffness, easy washing, quick drying, etc., and is popular with consumers. However, due to the smooth surface of polyester fibers, there are few reactive groups and the fibers (n f =1.73) and air (n 0 =1.0) the difference in refractive index is large, the incident light is largely reflected on the surface of the fiber, and only a small part of the light is refracted into the interior of the fiber, and is selectively absorbed by the dye to form colored light. Deep color effects such as navy blue, purple red, jet black, etc. Especially when the fiber fineness is reduced, the specific surface area of ​​the fabric is increased, and the reflective surface is great...
