Abstract
The invention discloses a composite cement plank with bagasse inner layer, and a manufacturing method thereof. The composite cement plank comprises a calcium silicate board layer, a foamed cement layer and a bagasse inner layer which are arranged sequentially from outside to inside, wherein the bagasse inner layer comprises a plurality of bagasse strips which are arranged in a crossing manner; a heat-insulating layer is arranged between the bagasse inner layer and the foamed cement layer, and is a furnace slag layer. The bagasse strips are added in the traditional foamed cement, so that the tenacity of the foamed cement can be improved, the bending resistance performance is enhanced, and no complete breakage occurs even if being subjected to strong impact.
Description
Technical field
The present invention relates to a kind of cement batten and preparation method thereof, more particularly, to a kind of compound with bagasse internal layer
Cement batten and preparation method thereof.
Background technology
The light weight cement plate that prior art is used for building partition is sent out generally by pouring between two pieces of calcium silicate boards
Soaked mud is fabricated by, this light weight cement plate light weight, and hardness is big, meets user's building demand, but poor toughness, it is being subject to
It is easily broken off when strong impact or long-time use.
The material that bagasse is Caulis Sacchari sinensis to be stayed after extruding is squeezed the juice, not size-reduced before, sugarcane epidermis have extraordinary
Toughness.In addition, draining the bagasse bar lighter weight after moisture, its loose fibre structure also has good absorbing sound and lowering noise effect
Really.Temporarily do not find to be used for producing the record of cement batten by bagasse in prior art.
Content of the invention
It is an object of the invention to provide a kind of complex cement batten with bagasse internal layer and preparation method thereof is it is intended to solve
The poor technical problem of certainly traditional foam cement bar bending resistance compressive property.
Technical scheme is as follows: a kind of complex cement batten with bagasse internal layer, wherein, including successively by outer
To the calcium silicates flaggy of interior setting, foam cement layer and bagasse internal layer, described bagasse internal layer includes many cross arrangements settings
Bagasse bar；It is additionally provided with thermal insulation layer, described thermal insulation layer is slag layer between described bagasse internal layer and foam cement layer.
Bagasse is the material obtaining after Caulis Sacchari sinensis drain moisture, and the epidermis of Caulis Sacchari sinensis is long fibre structure, has very strong toughness,
Easily with sharp weapon cut-out, it can be difficult to being pulled off.Caulis Sacchari sinensis after squeezing is processed, the epidermis stronger except having toughness, its
The fibre structure of internal defect not only light weight, and there is preferable sound insulation and noise reduction effect and buffering effect.Inventor finds
Bagasse bar is applied in cement board, on the one hand can improve toughness and the voltage endurance capability of cement plate, even if cement plate is subject to
To thump fracture, its internal bagasse bar also will not be easily by tear fracture；On the other hand can preferably improve cement plate every
Audio fruit.
Because bagasse bar after treatment is combustible, therefore in order to ensure the safety of cement plate it is necessary to sugarcane
Slag bar is thermally shielded.Slag is the material that fuel stays after high-temp combustion, is vesicular texture, and inventor finds slag tool
There is very excellent effect of heat insulation, be therefore respectively provided with slag layer in bagasse layer both sides, to improve the heat-resisting safety of cement plate.This
In invention, the composition of raw materials of slag layer is to be grouped into by each group of following parts by weight:
