Embodiment 1

[0062] 70 parts by mass of stearyl acrylate, 30 parts by mass of dodecyl acrylate, 5 parts by mass of alcohol a, 5 parts by mass of triethylene glycol, 2 parts by mass of S-60, 4 parts by mass of AEO-9, 1 part by mass of AC -1810, 3 parts by mass of octadecyltrimethylammonium chloride, 0.5 parts by mass of acetic acid and 200 parts by mass of water were added to the reaction kettle, and the temperature was raised 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 of reaction to obtain the dispersion liquid of the fabric waterproofing treatment composition of the present invention.

Embodiment 2 and comparative example 1～3

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

[0065] Table 2 Process formula table (mass parts in the table)

[0066]

[0067] AIBA is azobisisobutylamidine hydrochloride, the same below.

Embodiment 3 and comparative example 4

[0069] Using the same process as in Example 1, the specific formula is shown in Table 3.

Abstract

The invention discloses a composition dispersing liquid for fabric waterproof treatment. The composition dispersing liquid comprises a non-fluorine acrylate polymer, a non-fluorine surfactant, an alcohol-containing composition and water, wherein the non-fluorine acrylate polymer contains at least 60wt% of acrylate unit with C14-C18 alkyl and at most 40wt% of acrylate unit with C1-C12 alkyl; the alcohol-containing composition contains a compound shown in the formula of R-[Si(CH3)2O]x-[Si(CH3)(R1)O]y-Si(CH3)2R, R1 is a monovalence organic group at least containing three carbon atoms and a hydroxyl group, R is R1 or C1-C4 alkyl, and x and y are positive integers. The composition dispersing liquid for fabric waterproof treatment has the advantages that the stability is good, the roll sticking is avoided in the cloth rolling process after the fabric is impregnated, the treated fabric has excellent fireproof property and good washing-resistant property, and the original hand feel of the fabric can be well maintained; the continuous processing property of the dispersing liquid is excellent.

Description

technical field [0001] The invention discloses a composition dispersion liquid for fabric 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 polymer...
