Embodiment 1

[0040] The application examples given below can synthesize the adhesive described in this patent, and the application effect of the adhesive synthesized according to the formula in Table 1 is listed in Example 8.

[0041] Will be equipped with a stirrer, reflux condenser. Place the three-necked flask of the dropping funnel on a constant temperature water bath, add emulsifier and distilled water, stir, heat up to 78-80°C, add initiator, stir for 0.1 hour, add soft / hard monomer, hydrophilic monomer and For the pre-crosslinking monomer monomer, keep warm for 0.5 hours after the dropwise addition, then raise the temperature to about 85°C, keep warm for 1 hour, cool down, neutralize with alkali (ammonia water is recommended), filter, and discharge.

[0042] The synthesized adhesive has a particle diameter of about 100nm, is concentrated in distribution, and has excellent shear stability, acid and alkali resistance, electrolyte resistance and dilution resistance.

Abstract

This invention includes a kind of face baking-free formaldehyde coating dying nanometer adhesive water latex, the adhesive borns from the following steps. The pre-crosslinking monomer, soft monomer, hydrophilic monomer, anion and the non-ion types emulsify complex emulsifying agent and initiator. It is to get together the precrosslinking monomer, soft monomer, hard monomer, water hydrophile monomer , and get close to water get the hybrid body and initiator aqueous solution to join to emulsify to respond, moderate in the distilled waters, filter to make. This latex not only make in simple method, but also print to dye to process the application in the textile product, needing below 100 deg.C to dry but did not need to be baked, the hand feeling is soft, the degree of the wet or dry friction meets the request.

Description

Technical field: [0001] The utility model relates to the field of light chemical industry, in particular to a non-baking and formaldehyde-free paint dyeing nano-adhesive water-based latex, its preparation method and application, including the preparation of the water-based latex and its dyeing of paint on pure cotton and silk fabrics application. Background technique: [0002] At present, the components of known textile coating adhesives mostly contain active groups of methylolacrylamides, and the fabrics need to be baked at high temperature in the process of use to obtain ideal dry and wet rubbing fastness. . On the one hand, high temperature baking (usually around 150°C) will damage the physical properties of dyed fabrics. On the other hand, relying on the methylolacrylamide active group to produce crosslinking after high temperature action and the inevitable release of formaldehyde during the taking process, the environment is polluted. Recently, it has also been repor...
