Problems solved by technology

The initial wet molding strength of this fiber product is high, but it has a large volume, is easily broken, cannot be reused, and has a high one-time investment; later, it is formed by dry molding, but an outer protective layer is required. The thermal insulation performance of non-similar products is superior, but the application cost is high, and the products produced by these two methods are easy to absorb moisture and attach corrosive ions when they are suspended at room temperature or high temperature, causing severe corrosion on the surface of equipment or pipelines, especially stainless steel equipment. And pipelines are more serious and need to be replaced in advance, which shortens the service life of equipment and pipelines, causes waste of materials, and further increases application costs

Abstract

The invention relates to a fiber product of hydrophobe antisepticised aluminum silicate, namely coating a hydrophobe antisepticised wedding agent on the surface of aluminum silicate fibers. The hydrophobe antisepticised wedding agent is prepared by solidification agent, waterproof agent and distilled water, with proportion by weight of solidification agent: waterproof agent: distilled water=5-20:2-10:100, wherein the material proportion by weight of the solidification is phenol 20-60%, formaldehyde 30-70%, carbamide 5-20%, the material proportion by weight of the waterproof agent is that organic silicon oil emulsifiable solution is 45-70%, and hydrophile is 30-55%. The product has functions of both thermal insulation and hydrophobe and antisepticising, the hydrophobe rate is 98%, and service life of devices and pipelines is prolonged.

Description

technical field [0001] The invention belongs to the category of thermal insulation materials, and in particular relates to a water-repellent and anti-corrosion aluminum silicate fiber product and a processing method thereof. Background technique [0002] In my country, aluminum silicate fiber products originated in the 1970s. Because of their light bulk density, small heat capacity, low thermal conductivity, easy construction, and easy installation, they are not only used as lining materials, but also used in thermal insulation of high-temperature equipment and pipelines. has been well applied. The fiber product has high initial wet molding strength, but it has a large capacity, is easily broken, cannot be reused, and has a high one-time investment; later, it is formed by dry molding, but an outer protective layer is required. The thermal insulation performance of non-similar products is superior, but the application cost is high, and the products produced by these two metho...
