Embodiment 1

[0057] Preparation of rosin-modified silicone wax (SW-1), the structural formula of SW-1 conforms to formula II, wherein a=20, b=20, c=20, d=60, n=15.

[0058] The preparation method is as follows:

[0059] Under the protection of nitrogen, mix 20g of 1-hexadecene and 0.2g of chloroplatinic acid hexahydrate solution (mass concentration is 1%, solvent is methyl isopropyl ketone), mix well, and slowly add 26.5g of hydrogen-containing silicone oil after heating up to 120°C (hydrogen content is 0.34%), the dropwise addition is completed within 4 hours and the insulation reaction is continued for 2 hours; Concentration is 5%), slowly warming up to 140 ℃ within 2 hours, continue to stir the reaction for 2 hours, and finally under the pressure of 5kPa vacuum deboil for 2 hours to obtain the amino-modified silicone wax product; slowly add 26.9 g hydrogenated rosin powder, heat preservation reaction at 140°C for 2 hours, and remove low boiling under a pressure of 5kPa for 2 hours; aft...

Embodiment 2

[0062] Preparation of rosin-modified silicone wax (SW-2), the structural formula of SW-2 conforms to formula II, wherein a=20, b=20, c=20, d=60, n=17.

[0063] According to the preparation method shown in Example 1, the raw material 1-hexadecene was replaced with 1-octadecene, and the corresponding mass became 22.5 g, and the others were the same as in Example 1.

Embodiment 3

[0065] Preparation of rosin-modified silicone wax (SW-3), the structural formula of SW-3 conforms to formula II, wherein a=20, b=30, c=10, d=60, n=15.

[0066] According to the preparation method shown in Example 1, the quality of the raw material monoepoxide-terminated polyoxyethylene ether was changed to 22.2 g, and the quality of hydrogenated rosin was changed to 40.4 g, and the others were the same as in Example 1.

Abstract

The invention relates to a rosinyl fluoride-free waterproof agent and a preparation method thereof. The rosinyl fluoride-free waterproof agent is prepared from the following raw materials in parts by weight: 10-100 parts of rosin-modified silicon wax, 5-20 parts of polyether urethane resins, 5-20 parts of cross-linking agents, 1-15 parts of emulsifying agents, 10-200 parts of solvents and 100-300 parts of water. The rosinyl fluoride-free waterproof agent provided by the invention is arranged as an environment-friendly waterproof agent; the waterproof agent is free from fluorocarbon compound; the defect of poor dynamic siphon-proof property of the fluoride-free waterproof agent in the prior art is overcome; the rosinyl fluoride-free waterproof agent has excellent static siphon-proof property; the defect of poor adhesive force of the waterproof agent product and superfine fiber synthetic leather base cloth in the prior art is overcome; the green reproducible natural rosin or ramification thereof is taken as the raw material, so that the waterproof agent has an important value of environmental protection and ultra-wide application prospect; the preparation is simple and environment-friendly.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to an environment-friendly rosin-based fluorine-free waterproofing agent and a preparation method thereof. Background technique [0002] Microfiber synthetic leather is composed of nylon microfiber and polyurethane, which has the characteristics of genuine leather and is superior to genuine leather. It is comparable to high-grade natural leather, and has the inherent moisture absorption and breathability of natural leather. It is not only suitable for modern large-scale production, but also can protect ecology, reduce environmental pollution, and make full use of non-natural resources. In its base fabric structure, the microfibers are three-dimensionally cross-linked to act as a skeleton and support, forming a structure similar to dermal collagen fibers. Distributed around the fibers is polyurethane, which makes the entire synthetic leather base fabric a whole. However, the fl...
