The surface layer is composed of the following raw materials in parts by weight: acrylate emulsion (5-20 ℃ Tg): 30 parts of acrylate oligomer emulsion: 15 parts of polyurethane dispersion emulsion (modulus 5-10): 5 parts of titanium dioxide: 35 parts of filler (kaolin) 2 parts of foam stabilizer: 12 parts of cross-linking agent: 0.1 part of hydroxylated fullerene C60.12 parts and 0.1 part of dispersing agent.
The solid content of the acrylic emulsion (Tg of 5-20 ℃): 50%, particle size: 120-200nm, with a multifunctional group that can be crosslinked with silicone or other crosslinking agents.
The acrylate oligomer emulsion: has lower molecular weight, molecular weight distribution of 5000-20000, better molecular chain flexibility after film forming, and plasticizer effect.
The polyurethane dispersion emulsion (modulus 5-10): the film is more compact, the strength of the film is improved, and the coating has better low-temperature flexibility.
The titanium dioxide is rutile titanium dioxide, and has excellent weather resistance and good covering performance;
the foam stabilizer is ammonium stearate foam stabilizer.
The cross-linking agent is an organosilicon or carbodiimide cross-linking agent.
The dispersing agent is a high molecular modified polymer.
Comparative example 1
The hydroxylated fullerene C60 of example 1 was replaced with non-hydroxylated fullerene C60, the balance and the preparation method being unchanged.
Comparative example 2
The hydroxylated fullerene C60 of example 1 was removed, the remaining ratios and preparation methods were unchanged.
The test is described in GB/T3819-1997 test for determination of recovery Angle method of crease recovery of textile fabrics. The sum of the warp slow elastic recovery angle and the weft slow elastic recovery angle reflects the crease resistance of the fabric, and the specific detection results are shown in table 1.
Table 1: the anti-crease performance compares the test results.
From the above test data, it can be seen that the low temperature anti-cracking roller shutter fabric of the present invention has little difference between normal temperature and high temperature properties, but has a very large difference between low temperature properties, compared with the comparative example.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
