Embodiment 1

[0059] The basalt thermal insulation material is made of chopped basalt yarns with a length of 7 cm and a length of 12 cm through mixing, opening, carding, net laying and acupuncture; wherein the chopped basalt yarns with a length of 7 cm account for the total amount of materials. 70% of the mass, basalt chopped strands with a length of 12cm accounted for 30% of the total mass of the material;

[0060] And made by the following steps:

[0061] (1) Mixing: After mixing the two kinds of basalt chopped strands with a mixer, stir in the material box to make the two kinds of chopped strands fully mixed and fluffy; the mixing time is 0.5 hours, and the rocker arm speed is at 30~50 rev / min;

[0062] (2) Opening: use an opening machine to open the chopped yarn mixed in step (1) to form a single fiber, and put it into a hopper;

[0063] (3) Carding: Two carding machines comb the fibers in the material box out of the net, and the basalt fiber that has been loosened in step (2) is made...

Embodiment 2

[0072] The basalt thermal insulation material is made of chopped basalt yarns with a length of 7 cm and a length of 12 cm through mixing, opening, carding, net laying and acupuncture; wherein the chopped basalt yarns with a length of 7 cm account for the total amount of materials. 75% of the mass, basalt chopped strands with a length of 12cm accounted for 25% of the total mass of the material;

[0073] And made by the following steps:

[0074] (1) Mixing: After mixing the two kinds of basalt chopped strands with a mixer, stir in the feed box to make the two kinds of chopped strands fully mixed and fluffy; the mixing time is 0.8 hours, and the rocker arm speed is at 30~50 rev / min;

[0075] (2) Opening: use an opening machine to open the chopped yarn mixed in step (1) to form a single fiber, and put it into a hopper;

[0076] (3) Carding: Two carding machines comb the fibers in the material box out of the net, and the basalt fiber that has been loosened in step (2) is made int...

Embodiment 3

[0085] The basalt thermal insulation material is made of chopped basalt yarns with a length of 7 cm and a length of 12 cm through mixing, opening, carding, net laying and acupuncture; wherein the chopped basalt yarns with a length of 7 cm account for the total amount of materials. 80% of the mass, basalt chopped strands with a length of 12cm accounted for 20% of the total mass of the material;

[0086] And made by the following steps:

[0087] (1) Mixing: After mixing the two kinds of basalt chopped strands with a mixer, stir them in the material box, so that the two kinds of chopped strands are fully mixed and fluffy; the mixing time is 0.6 hours, and the rocker arm speed is at 30~50 rev / min;

[0088] (2) Opening: use an opening machine to open the chopped yarn mixed in step (1) to form a single fiber, and put it into a hopper;

[0089] (3) Carding: Two carding machines comb the fibers in the material box out of the net, and the basalt fiber that has been loosened in step (...

Abstract

The invention relates to a basalt needling thermal insulation material and a manufacturing process thereof, belonging to the technical field of thermal insulation materials. The basalt needling thermal insulation material is prepared from basalt chopped yarns with the lengths of 5-7 cm and 8-12 cm through the processes of mixing, opening, carding, lapping and needling, wherein the basalt chopped yarn with the length of 5-7 cm is 70-80% of the total weight of the material, and the basalt chopped yarn with the length of 8-12 cm is 20-30% of the total weight of the material. The novel basalt needling thermal insulation material provided by the invention is wider in temperature application range and higher in breaking strength.

Description

technical field [0001] The invention relates to a novel basalt needle-punched thermal insulation material and a manufacturing process thereof, belonging to the technical field of thermal insulation materials. Background technique [0002] Glass fiber products are mainly used in my country's thermal insulation market, and the maximum temperature resistance of glass fiber thermal insulation materials is 600 °C. The further development of glass fiber thermal insulation materials is limited. The basalt fiber fills the gap in the use of thermal insulation materials at 600°C-960°C. 99% of the raw materials of basalt fiber thermal insulation materials are natural basalt rocks, which are rich in sources and low in price, which not only conforms to the principle of sustainable development, but also has good environmental benefits. In the production process, there is no substance that pollutes the environment, and there is no harm to the environment. Since basalt fiber needle-punch...
