preparation example Construction

[0040] The preparation method of ceramic fiber heat insulation pad includes the following steps:

[0041] S1, select aluminum silicate fibers; select aluminum silicate fibers with an aluminum content of 45-55%, a fiber diameter of 2-5μm, a specific gram value of 400-800ml, a fiber length of 2-50mm, and a fiber toughness of 300-600ml ;

[0042] S2, mixing aluminum silicate fiber and water for stirring and pulping, wherein the proportion of aluminum silicate fiber is not less than 3%, the stirring speed is 0-350r / min, the stirring time is 0-10min, until the fiber is in the slurry The specific gram value is not less than 300ml, the fiber content has not changed, and the product has a good dispersion effect. The blades of the mixing blade need to be treated during mixing and pulping, and the mixing head is replaced by a common propeller type and a multi-layer type to a combination of the two. The blade is converted from multiple layers to one layer, the blade blades are blunt, and th...

Embodiment 1

[0048] The ceramic fiber heat insulation pad is made of the following mass percentages of raw materials: 92% aluminum silicate fiber raw cotton, 7% organic binder, and 1% auxiliary agent.

[0049] This scheme uses ordinary aluminum silicate fiber, that is, the alumina content of the fiber raw cotton component is 45%, and the fiber is soft and tough. The specific gram value of raw cotton is 500ml. The organic binder is a water-based acrylic resin.

[0050] The auxiliary agent used in this scheme is silicate. The addition of such additives can effectively disperse the fiber, reduce the surface charge, make the fiber soft, and improve the retention of the organic binder in the fiber.

[0051] The preparation process is as follows: first weigh the aluminum silicate fiber cotton at a concentration of 3% (mix 3% aluminum silicate fiber with 97% water), and then place the aluminum silicate fiber and water in a mixing tank. Stir at a speed of 300r / min for 10 minutes to configure a uniform...

Embodiment 2

[0059] The ceramic fiber heat insulation pad is made of the following mass percentages of raw materials: 95% aluminum silicate fiber raw cotton, 4% organic binder, and 1% additive.

[0060] This scheme uses ordinary aluminum silicate fiber, that is, the alumina content of the fiber raw cotton component is 50%, and the fiber is soft and tough.

[0061] The organic binder is a water-based polyurethane resin.

[0062] The auxiliary agent used in this scheme is alkali metal phosphate. Additives added to the product can effectively disperse the fiber, reduce the surface charge, make the fiber soft, and improve the retention of glue in the fiber.

[0063] Preparation process: first weigh the aluminum silicate fiber cotton at a concentration of 3%, then place the aluminum silicate fiber cotton in a mixing tank and stir at 200r / min for 10 minutes to configure to 0.2% or 1% or 2% or 3% uniform slurry, so that the fiber ratio in the slurry is 400ml or 450ml or 500ml.

[0064] When forming, the ...

Abstract

The invention discloses a ceramic fiber heat insulation pad. The ceramic fiber heat insulation pad is characterized by being prepared from raw materials in percentage by mass as follows: 92%-97% of aluminium silicate fibers, 1%-8% of organic binding agents and 1% of auxiliaries. According to the ceramic fiber heat insulation pad, defects that a product is prone to cracking and is not easily bent for shaping are overcome, and the new product can be bent for 180 degrees without cracking and can be shaped randomly. With optimization of a formula, the product has higher tensile and compression performance; length and strength of fibers are guaranteed, and the product has better deflation resistance. The product not only has good bending performance, but also has excellent tensile strength and compression strength. A domestic heat insulation product is prone to cracking and is not shaped easily, while the heat insulation product has good bending performance and can be shaped randomly.

Description

Technical field [0001] The invention relates to a ceramic fiber heat insulation pad and a preparation method thereof. Background technique [0002] Ceramic fiber is an excellent inorganic non-metallic material. Its products have a variety of properties such as heat insulation, fire resistance, corrosion resistance and sound insulation. Compared with traditional asbestos, it has better human and environmental safety; compared with glass fiber, it has higher Better performance under temperature. Moreover, it has a wide range of applications, with good applications in industries, automobiles, aerospace, building materials and other fields. [0003] At present, the quality of ordinary ceramic thermal insulation products on the market is uneven, and customer requirements are constantly increasing. The prices of imported products are too expensive for ordinary enterprises to bear. In order to meet various customer needs, the market urgently needs a comprehensive Excellent performance c...
