Embodiment 1

[0062] 70 parts by mass of stearyl acrylate, 27 parts by mass of dodecyl acrylate, 3 parts by mass of hydroxyethyl acrylate, 5 parts by mass of triethylene glycol, 4 parts by mass of AEO-9, 2 parts by mass of E-1306, 1 Add parts by mass of AC-1810, 3 parts by mass of octadecyltrimethylammonium chloride, 5 parts by mass of surfactant a, 0.5 parts by mass of acetic acid and 210 parts by mass of water into the reactor, and heat up to 40-45°C for pre-emulsification . Then homogenize under high pressure for 30 minutes at a pressure of 30 MPa, transfer the homogenized solution to the reaction kettle, and start stirring. 0.5 parts by mass of the initiator AIBA was dissolved in 2 parts by mass of water to form a homogeneous solution, which was added to the reaction kettle. Then the temperature was raised to 70-75° C. for 5 hours to obtain the dispersion liquid of the composition for water repellent treatment of the present invention.

Embodiment 2

[0064] Using the same process as in Example 1, the specific formula is shown in Table 2.

Embodiment 3

[0066] 60 parts by mass of stearyl methacrylate, 10 parts by mass of behenyl methacrylate, 10 parts by mass of dodecyl methacrylate, 10 parts by mass of tert-butyl methacrylate, 3 parts by mass of hydroxyethyl acrylate , 10 parts by mass of triethylene glycol, 5.5 parts by mass of AEO-9, 3 parts by mass of E-1306, 1.5 parts by mass of AC-1810, 0.5 parts by mass of acetic acid and 210 parts by mass of water were added to the reaction kettle, and the temperature was raised to 40-45°C. pre-emulsified. Then homogenize under high pressure for 30 minutes at a pressure of 30 MPa, transfer the homogenized solution to the reaction kettle, and start stirring. 0.5 parts by mass of the initiator AIBA was dissolved in 2 parts by mass of water to form a homogeneous solution, which was added to the reaction kettle. Then the temperature was raised to 70° C. to start the timing reaction, and 7 parts by mass of vinyl chloride was introduced within 1 hour after the reaction started. Continue t...

Abstract

The invention discloses a composition dispersion liquid used for water repellent treatment. The composition dispersion liquid used for water repellent treatment contains a non-fluoroacrylate polymer, and a surfactant composition represented by R-[Si(CH3)2O]x-[Si(CH3)(R1)O]y-Si(CH3)2R; the non-fluoroacrylate polymer contains at least 59wt% or more of C14-30 acrylate monomers, at most 40wt% C1-12 acrylate monomers, and 1wt% or more a cross-linking monomer; R1 is used for representing an univalent organic group, R is used for representing R1 or C1-4 alkyl, x and y are selected from positive integers; and water is taken as a cosolvent. The composition dispersion liquid used for water repellent treatment is excellent in stability; roll banding in cloth banding after dipping is not caused; water resistance of fabric processed with the composition dispersion liquid used for water repellent treatment is excellent; washing fastness is high; the original handfeel of processed fabric can be maintained preferably; and the continuous processing performance of the composition dispersion liquid used for water repellent treatment is excellent.

Description

technical field [0001] The invention discloses a composition dispersion liquid for waterproof treatment, which belongs to the technical field of fabric waterproof treatment auxiliary agent production. Background technique [0002] Fluoropolymers have incomparable advantages in surface activity, water repellency, oil repellency, dirt repellency, heat resistance and corrosion resistance, which can endow products with good water and oil repellency. However, such fluoropolymers usually contain long-chain fluoroalkyl groups, especially C 8 The perfluoroalkyl compounds are derivatives of PFOA or PFOS. Due to their high persistence and accumulation in the environment, they are potentially dangerous, so they are strictly restricted in many countries, especially developed countries. In addition, fluoropolymers are relatively expensive. Therefore, the development of fluorine-free waterproofing agents has become a development trend. [0003] Long-chain alkane acrylate polymers are w...
