Problems solved by technology

[0003] However, due to the single performance of these non-metallic minerals, and some non-metallic mineral products also have relatively large pollution, in order to design a granular sound-insulating and heat-insulating material that can not only sound insulation and heat preservation, but also easy to use, pollution-free and cheap, With the above materials, it is difficult to achieve
[0004] Although perlite, vermiculite and other materials have granular products, and the use effect is also good, but because they are too light in texture, low in extrusion strength, and easy to break, the use effect is not ideal, and the actual input cost is high. Not conducive to promotion

Embodiment Construction

[0019] 1. Ingredients composition, calculated by weight percentage:

[0020] 1. Material selection: These four kinds of raw materials will be mixed with some dead branches, rotten leaves, gravel, soil and other impurities. Strict checks must be made before the ingredients to remove these impurities. After natural weathering, it can be put into production after about 30 to 45 days. The fineness of anhydrite ore is ≤3.0 mm, and the fineness of sawdust is ≤1.5 mm.

[0021] 2. Ingredients: 55% attapulgite ore, 20% bentonite ore, 15% anhydrite ore, and 10% sawdust.

[0022] Two: Production process steps:

[0023] 1. Stirring, extruding, and drying: Stir the prepared raw materials together evenly, input them into a double-roller machine, and extrude them into flakes with a thickness of 2 to 3 mm, and transport them to the cement drying yard for drying, and the flakes after drying The water content of the food should be ≤15%.

[0024] 2. Grinding: Grinding the dried raw materials ...

Abstract

The present invention discloses one kind of sound isolating and heat insulating granular attapulgite material and its production process. The present invention features that the material including attapulgite, bentonite, anhydrite ore, wood dust, etc. is produced into the sound isolating and heat insulating granular attapulgite material through stirring, extruding, drying, milling, pelletizing, stoving, sieving and packing. The sound isolating and heat insulating granular attapulgite material has high sound isolating and heat insulating effect, high stability, no deformation, mothproofing, no pollution, easy use and low production cost, and may be used for isolating sound and insulating heat in various fields and also as desiccant.

Description

Technical field: [0001] The invention relates to a sound-insulating and heat-insulating material, in particular to a particle attapulgite sound-insulating and heat-insulating material and a production process thereof. Background technique: [0002] Nowadays, there are many kinds of sound insulation materials, especially in non-metallic minerals, the relevant insulation materials prepared with perlite, diatomaceous earth, asbestos, slag wool, vermiculite and limestone as the main raw materials occupy a dominant position. [0003] However, due to the single performance of these non-metallic minerals, and some non-metallic mineral products also have relatively large pollution, in order to design a granular sound-insulating and heat-insulating material that can not only sound insulation and heat preservation, but also easy to use, pollution-free and cheap, With the above materials, it is difficult to realize. [0004] Although perlite, vermiculite and other materials have granu...
