Embodiment 1

[0026] An energy-saving board, the ratio of each component of the energy-saving board is as follows: expected 30%~50%, fiber material 15%~35%, cement 15%~35%, filler 3%~ 5%, adhesive 1%~5%, wherein, the said material is expected to contain calcium silicate, and the sum of the content of each component is 100%.

[0027] Further, the prediction is generated under the action of calcium hydroxide, silicon dioxide, water and a catalyst, wherein the molar ratio of calcium hydroxide to silicon dioxide is between 05-0.9, and the catalyst accounts for the 1% of the total mass of calcium and silicon dioxide.

[0028] Further, the catalyst is nickel.

[0029] Further, the fibrous material is wood pulp, and the filler is polyurethane foam.

[0030] Further, the adhesive is any one of isocyanate resin, melamine-formaldehyde resin, phenolic resin, urea-formaldehyde resin or a mixture thereof.

[0031] An energy-saving board processing technology, characterized in that it comprises the fo...

Abstract

The invention provides an energy saving board and a processing technology thereof. The energy saving board is prepared from, by weight, 30-50% of prepared material, 15-35% of fiber type material, 15-35% of cement, 3-5% of filler and 1-5% of adhesive, wherein the prepared material is a material containing calcium silicate, and the sum of the contents of all the components is 100%. The final energy saving board is formed by preparing calcium silicate from calcium hydroxide and quartz powder and mixing the various materials; by adding polyurethane foam, a light calcium silicate board with low density and high strength can be prepared; the technology is simple and can be completed according to an existing technological process without changing an existing calcium silicate board production line or production conditions, cost is not increased in the production process, and a good effect can still be achieved.

Description

technical field [0001] The invention relates to an energy-saving board and its processing technology, in particular to a low-density calcium silicate board and its processing technology. [0002] technical background [0003] At present, the development trend of the world's building materials industry is to produce light, high-strength, energy-saving and environmentally friendly building materials. The development direction of the construction industry is to use light and high-strength building materials to reduce the weight of buildings and improve construction efficiency level of mechanization and assembly. At present, the calcium silicate board produced industrially belongs to medium and high density, mainly at 1.1g / m 3 Above, in order to comply with the development of the building materials market, it is imperative to develop lightweight calcium silicate boards. [0004] The density of the existing low-density calcium silicate board is generally 0.6-0.9g / cm 3 However, ...
