Abstract

The invention relates to a cement particle board, in particular to a cement particle board and a preparation method thereof, which belong to the technical field of machining of building materials. The method comprises the following steps of: adding an aid into Portland cement serving as a bonding material and wood particle or straw serving as a reinforcing rib material; stirring raw materials, and paving a board blank; and performing hot pressing and indoor curing, steaming by using a steaming kettle, and drying to obtain a finished product. The cement particle board can be widely taken as ceiling boards, non-bearing inner partition wall boards, floor boards, roof boards and outer wall boards of various buildings, and has the characteristics of high intensity, high fire resistance, high water resistance, high sound insulation and high thermal insulation property.

Description

Cement-bonded wood chipboard and preparation method thereof
Technical field
The present invention relates to a kind of particieboard, be specifically related to a kind of cement-bonded wood chipboard and preparation method thereof, belong to the construction material processing technique field.
Background technology
At present, along with socioeconomic fast development, the various places building industry is surging forward, drive the construction material demand and roll up, cement-bonded wood chipboard has good physical and mechanical property, waterproof fireproofing performance, is a kind of novel wall material and decorating and renovating material of high comprehensive performance, but the production and processing technology of cement-bonded wood chipboard is relatively backward, yield poorly down, needed raw material is single, and finished product output, quality all can't be met the need of market.
Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, a kind of cement-bonded wood chipboard and preparation method thereof is provided, this method is cementing material with the portland cement, with wood particle or stalk is the reinforcement material, add auxiliary agent, mat formation into slab after raw material stirs, carrying out through hot pressing, indoor maintenance, steam-cured still that steam-cured back is dry again must finished product.Cement-bonded wood chipboard can be widely used as various buildings ceiling ceiling board, non-bearing inner partition plate, panel, roof boarding, Side fascia.
The present invention realizes with following technical scheme: a kind of cement-bonded wood chipboard, with the portland cement is cementing material, with wood particle or stalk is the reinforcement material, it is characterized in that: this cement-bonded wood chipboard raw material proportioning comprises following weight portion: 10~40 parts of dried wood wool or stalks, 18~50 parts in flyash, 30~60 parts of cement, 1~3 part of sodium metasilicate, calcium oxide 0.3-1.8 part, 0.1~2 part of auxiliary agent.
Described auxiliary agent is one or more in sodium chloride, gypsum, calcium hydroxide, the sodium sulphate.
A kind of method for preparing the described cement-bonded wood chipboard of claim 1, it is characterized in that: a), wood wool, flyash, cement, sodium metasilicate, calcium chloride, water and auxiliary agent are mixed, stir, mat formation into slab then, to the pressurization of slab buttress, pressure is 3.5-4.5MPa; B), slab buttress is sent into indoor maintenance, indoor temperature is 70 ℃-90 ℃, curing time 8-12 hour; C), to send the sheet material of maintenance steam-cured still to carry out steam-cured, pressure is 1.8-4MPa, the time is 8-16 hour, then cooling; D), sheet material is carried out drying, baking temperature is 60 ℃-75 ℃, makes moisture content reach 5%-10%.
Advantage of the present invention is: this method is cementing material with the portland cement, is the reinforcement material with wood particle or stalk, adds auxiliary agent, mats formation into slab after raw material stirs, and carrying out through hot pressing, indoor maintenance, steam-cured still that steam-cured back is dry again must finished product.Cement-bonded wood chipboard can be widely used as various buildings ceiling ceiling board, non-bearing inner partition plate, panel, roof boarding, Side fascia, have that intensity height, fire protection flame retarding are good, resistance to water and good characteristics of sound-insulating performance.
The specific embodiment
Below in conjunction with embodiment the present invention is described in further detail:
Embodiment,
A kind of cement-bonded wood chipboard, with the portland cement is cementing material, with wood particle or stalk is the reinforcement material, this cement-bonded wood chipboard raw material proportioning comprises following weight portion: 10~40 parts of dried wood wool or stalks, 18~50 parts in flyash, 30~60 parts of cement, 1~3 part of sodium metasilicate, calcium oxide 0.3-1.8 part, 0.1~2 part of auxiliary agent.
Described auxiliary agent is one or more in sodium chloride, gypsum, calcium hydroxide, the sodium sulphate.
A kind of method for preparing the described cement-bonded wood chipboard of claim 1 a), wood wool, flyash, cement, sodium metasilicate, calcium chloride, water and auxiliary agent are mixed, stirs, and mats formation into slab then, and to the pressurization of slab buttress, pressure is 3.5-4.5MPa; B), slab buttress is sent into indoor maintenance, indoor temperature is 70 ℃-90 ℃, curing time 8-12 hour; C), to send the sheet material of maintenance steam-cured still to carry out steam-cured, pressure is 1.8-4MPa, the time is 8-16 hour, then cooling; D), sheet material is carried out drying, baking temperature is 60 ℃-75 ℃, makes moisture content reach 5%-10%.
