Problems solved by technology

[0004] Although the performance of fluorine-containing acrylate waterproofing agent is very good, it is expensive. The main reason is that the price of fluorine-containing acrylate monomer is high, and the proportion of fluorine-containing monomer in the synthesis of such fluorine-containing materials is large. reason

Embodiment 1

[0028] At room temperature, mix 18 parts of methyl methacrylate, 12 parts of butyl methacrylate, 15 parts of octadecyl methacrylate, 12 parts of dodecafluoroheptyl methacrylate, 2 parts of N-methylolpropene Acyl, 1 part of styrene, 2 parts of sodium lauryl sulfate, 0.5 part of n-dodecyl mercaptan, and 100 parts of deionized water are added to the reactor; install the condenser, nitrogen conduit, stirrer, thermometer, and heater , pre-emulsified for 1 hour; blow nitrogen and heat up to 85°C, add 0.5 parts (NH 4 ) 2 S 2 o 8 , heat preservation reaction for 4 hours; finally cooled to room temperature to obtain a flowable O / W type polymer emulsion which is the fluorine-containing material described in the present invention, its solid content is about 38.5%, and the consumption of fluorine-containing monomer is 19.2%. The results of various performance measurements are shown in Table 1.

Embodiment 2

[0030] Initiator with 0.003mol NaHSO 3 ~(NH 4 ) 2 S 2 o 8 (molar ratio 1: 1) instead, the heat preservation reaction temperature is 30 ℃, and the reaction time is 2 hours, and other raw material consumption and operation steps are identical with embodiment 1. The results of various performance measurements are shown in Table 1.

Embodiment 3

[0032] The emulsifier in Example 1 is changed to 1 part of sodium lauryl sulfate and 1 part of OP-10, and the amount of other raw materials, reaction conditions and operating steps are the same as in Example 1. The results of various performance measurements are shown in Table 1.

Abstract

This invention relates to a low fluorine material used for fabric treatment or paper, leather, wood, rock and other materials surface treatment and protection. It is a O/W type emulsion, includes fluorolkyl methacrylate or fuoroalkyl acrylate or both, acrylic ester or metharylate active or both, substitute ethylene with active radicals, modified monomeric random copolymerization, and the use of monomer with fluorine is below 20%. The method is also opened. This material not only makes protected materials acquire good property such as water proof, oil proof, anti-fouling, gas permeation, but also has ability of solvent resistance, acid resistance, alkali stability, and resistance to aging.

Description

technical field [0001] The present invention relates to a material for waterproof, oil-proof, stain-proof, breathable and moisture-permeable finishing of textiles or for surface treatment and protection of paper, leather, wood, stone and other materials, and also relates to the synthesis of the material method. Background technique [0002] The waterproof and oil-proof treatment of textiles, leather, paper, wood, stone and other materials has always been a topic of concern. Water repellents mainly include paraffin, fatty acid triazine, organosilicon, and organofluorine, among which the first two are less used at present, organosilicon has excellent softness, very good hydrophobic effect, synthetic and industrial production process It is very mature and low in cost, but it is not oil-proof and cannot meet the requirements of complete anti-fouling; organic fluorine water repellents (especially fluorine-containing acrylate polymers) not only have excellent waterproof, oil-proo...
