Problems solved by technology

But this kind of short fiber basalt material cannot be made into thicker material (generally less than 65mm) due to the reduced toughness, otherwise it will be easily broken due to insufficient toughness
Therefore, the heat insulation capacity is limited, which leads to the fact that the existing basalt fiber thermal insulation materials cannot be further applied in some fields with higher heat insulation requirements

Abstract

The invention provides a basalt ultra-high-temperature split material and a manufacturing process thereof and belongs to the technical field of thermal insulation materials. The basalt ultra-high-temperature split material is characterized in that the material is made of basalt fiber with the length of 17-23 cm, and the thickness is 4-10 cm. The manufacturing process comprises the steps that a flat curtain is utilized to deliver the mixed material filamentary basalt fiber to a splitting and web formation position after material mixing; then the mixed filamentary basalt fiber is split for web formation by utilizing a splitting machine, and the web is clamped through two rollers and is fed into a needling machine after splitting and web formation; the basalt fiber needled thermal insulation material is manufactured through simultaneous performing of upper needling and lower needling. The ultra-high-temperature split material is a new product replacing a traditional basalt fiber thermal insulation material, the basalt fiber split material is manufactured by adopting a splitting and web formation process, and a tighter organizational structure can be obtained by utilizing longer basalt fiber.

Description

technical field [0001] The invention relates to a basalt ultra-high temperature fiber-opening material and a manufacturing process thereof, which belong to the technical field of thermal insulation materials. Background technique [0002] Basalt fiber insulation materials can be used in high temperature environments. 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-punched thermal insulation materials are widely used in the field of thermal insulation materials, the scope of application of thermal insulation materials has been improved. The emergence of basalt fiber needle-punched thermal insulation materials is another great progr...
