Embodiment 1

[0048] A fabric laminate of recycled modified PVB, the laminate comprises a fabric layer and a modified PVB layer compounded on one surface of the fabric layer, the thickness of the modified PVB layer is 1.2 mm. In this embodiment, the fabric substrate is made of polyester yarn through a plain weaving process.

[0049] The preparation method of the fabric laminate of above-mentioned recovery modified PVB is as follows:

[0050] S1, the fabric layer is treated with corona equipment first, so that the surface energy of the fabric layer decreases, and the adhesion with the PVB layer is enhanced;

[0051] S2, 50kg of calcium carbonate was surface-treated with 1.8kg of vinyltriethoxysilane, specifically calcium carbonate and vinyltriethoxysilane were mixed and dispersed in a high-speed mixer for 5 minutes;

[0052] S3. Start the internal mixer, and after the temperature rises to 50°C, put 60kg of recycled PVB into the feeding port, and mix the rubber for 3 minutes; IRGAFOS 168 an...

[0055] A fabric laminate of recycled modified PVB, the laminate comprises a fabric layer and a modified PVB layer compounded on one surface of the fabric layer, and the thickness of the modified PVB layer is 1.0mm. In this embodiment, the fabric substrate is made of polyester yarn through a plain weaving process.

[0056] The preparation method of the fabric laminate of above-mentioned recovery modified PVB is as follows:

[0057] S1, the fabric layer is treated with corona equipment first, so that the surface energy of the fabric layer decreases, and the adhesion with the PVB layer is enhanced;

[0058] S2. Surface treatment of 50 kg of calcium carbonate with 1.6 kg of methacryloxytrimethoxysilane, specifically mixing and dispersing calcium carbonate and methacryloxytrimethoxysilane in a high-speed mixer for 5 minutes;

[0059] S3. Start the internal mixer, and after the temperature rises to 50°C, put 50kg of recycled PVB into the feeding port, and mix the rubber for 5 minut...

Embodiment 3

[0062] A fabric laminate of recycled modified PVB, the laminate comprises a fabric layer and a modified PVB layer compounded on one surface of the fabric layer, and the thickness of the modified PVB layer is 0.8mm. In this embodiment, the fabric substrate is made of polyester yarn through a plain weaving process.

[0063] The preparation method of the fabric laminate of above-mentioned recovery modified PVB is as follows:

[0064] S1, the fabric layer is treated with corona equipment first, so that the surface energy of the fabric layer decreases, and the adhesion with the PVB layer is enhanced;

[0065] S2, 50kg of calcium carbonate is surface-treated with 1.2kg of aminopropyltrimethoxysilane, specifically calcium carbonate and aminopropyltrimethoxysilane are mixed and dispersed in a high-speed mixer for 5 minutes;

[0066] S3. Start the internal mixer, and after the temperature rises to 50°C, put 70kg of recycled PVB into the feeding port, and mix the rubber for 5 minutes; ...

Abstract

The invention relates to a laminated fabric of recycled modified PVB and a preparation method thereof. The fabric laminate includes a fabric layer and a modified PVB layer compounded on the surface of the fabric layer, the thickness of the modified PVB layer is 0.02-2 mm, and the raw materials of the modified PVB layer include: PVB 20-99, isocyanate 0.1-10, Inorganic filler 0.4~60, silane coupling agent 0.1~2.0, plasticizer 0.1~10.0, antioxidant 0.1~2.0, lubricant 0.5~3.0; among them, the proportion of recycled PVB used is 0.1~100%. The present invention uses isocyanate and / or isocyanate prepolymer to modify the recycled PVB, so that sufficient self-adhesiveness can be produced between the PVB layer and the fabric layer, thereby avoiding gluing on the fabric layer. It solves a series of problems caused by gluing, such as environmental pollution in the workshop, complicated process, and high production cost.

Description

technical field [0001] The invention relates to a laminated fabric, in particular to a laminated fabric of recycled modified PVB and a preparation method thereof. Background technique [0002] Laminated fabrics, also known as bonded fabrics, laminated fabrics. It refers to the bonding of fabrics and other film materials to form a composite material with multiple functions, which is applied to raincoats, tents, etc. On the calender, the newly formed plastic film and fabric can be laminated to form artificial leather products. It can not only improve the appearance and feel of the fabric, but also improve the function of the fabric, such as making the fabric have special functions such as waterproof, breathable and moisture-permeable, flame-retardant and anti-fouling, and light-shielding reflection. [0003] In the prior art, PVC is commonly used for the manufacture of laminated fabrics or coated fabrics. The product has the advantages of low price, good flexibility, good e...
