Abstract
The invention discloses a production method of a magnesium oxide board. The method is characterized by comprising the steps of: (1) mixing the following raw materials by weight: 50-70 parts of magnesium oxide, 18-35 parts of magnesium chloride, 2-3 parts of bentonite, 6-15 parts of sawdust, 0.1-1 part of rosin, 3-6 parts of talcum powder, 1-6 parts of wollastonite powder, and 2-9 parts of essence; (2) conducting dilution according to that the rosin and water are in a weight ratio of 1:3; (3) putting the diluted rosin and other raw materials into a container, heating them under stirring, and introducing gas into the container so as to form bubbles in the slurry; (4) further stirring the slurry to make the slurry mixed and stirred uniformly; and (5) placing the uniformly mixed slurry into a die to carry out rolling molding, performing drying for 5h, and then releasing the die, thus obtaining the magnesium oxide board. The invention provides the production method of the magnesium oxide board with good halogen resisting performance, long service life and low production cost.
Description
Technical field
The invention belongs to building materials technology field, particularly relate to a kind of magnesium oxide plate production method.
Background technology
The magnesium oxide plate production method is a kind of novel multifunctional building materials, because of its lightweight and performance flexible and reprocessing that had both had wooden class organic plates, has inorganic plate fire resistance and water tolerance again.The magnesium oxide plate production method is applied in body of wall widely, and top ceiling is in the liner plate of floor.At present, but present oxidation plate is to be mixed and processed by magnesia oxychloride cement and some properties-correcting agent, and the PLASTIC LAMINATED moisture-sensitive of producing returns halogen and whiteness is not good, causes the bow warping strain cracking easily, has influenced the quality of product greatly, has limited the utilization of product.Simultaneously present magnesium oxide plate is because density is bigger, and the raw material usage quantity is big, and production cost is higher, and molding time is long, and make efficiency is low, and weight is also heavier in addition, and it is very inconvenient that carrying is used.
Summary of the invention
In order to address the above problem, the invention provides a kind of better anti-anti-halogen performance that has, work-ing life is longer, the magnesium oxide plate production method that production cost is low.
In order to address the above problem, the technical solution used in the present invention is:
A kind of magnesium oxide plate production method is characterized in that: may further comprise the steps:
(1), adopt following raw material to mix, each raw material weight umber is as follows: magnesium oxide 50-70 part, magnesium chloride 18-35 part, wilkinite 2-3 part, wood chip 6-15 part, rosin 0.1-1 part, talcum powder 3-6 part, wollastonite powder 1-6 part, essence 2-9 part;
(2), rosin and water are diluted according to the weight ratio of 1:3;
(3), rosin and other raw material of dilution are put into the container formation slurry that heats while stirring, and in container, charge into gas, in slurry, form bubble;
(4), continue to stir slurry, make the slurry mixing and stirring;
(5), the slurry after will mixing puts into the mould roller-compaction, the dry back demoulding in 5 hours forms magnesium oxide plate.
Aforesaid a kind of magnesium oxide plate production method is characterized in that: described gas forms by the whipping agent foaming.
Aforesaid a kind of magnesium oxide plate production method is characterized in that: preferred 60 parts of described magnesium oxide weight.
Aforesaid a kind of magnesium oxide plate production method is characterized in that: preferred 26 parts of described magnesium chloride weight.
Aforesaid a kind of magnesium oxide plate production method is characterized in that: preferred 10 parts of described wood chip weight.
Aforesaid a kind of magnesium oxide plate production method is characterized in that: preferred 5 parts of described talcum weight.
Aforesaid a kind of magnesium oxide plate production method is characterized in that: preferred 4 parts of described wollastonite powder weight.
Aforesaid a kind of magnesium oxide plate production method is characterized in that: preferred 6 parts of described essence.
The invention has the beneficial effects as follows: magnesium oxide plate production method magnesium oxide of the present invention and magnesium chloride can react as far as possible, can avoid taking place damp suction surface halide accumulation.In prescription, add wilkinite, can form fluid-tight closely knit colloid after the suction, can play waterproof action preferably, stoped the transmission of moisture in refractory slab.In prescription, also added rosin, sedimentation can not take place in rosin in magnesium oxychloride material, in participating in chlorine oxygen magnesium hardened process, coat crystal, form the excellent waterproof layer, has better anti-halogen effect, the present invention simultaneously adds solid essence in prescription, make the magnesium oxide plate production method can discharge light fragrance, and result of use is better.
The magnesium oxide plate density that the inventive method is made is low, in light weight, convenient in carrying, density is low simultaneously makes that also starting material are saved many when making, production cost is lower, owing to use starting material less, molding time is also shorter simultaneously, and it is also higher to make efficient, magnesium oxide plate of the present invention does not in addition use perlite, do the fire door material with it, when fire, can not use Environmental Safety more owing to the perlite burning causes toxic smoke.
