Abstract
The invention discloses an environment-friendly building material and a preparation method thereof. The building material mainly comprises, by weight, 70-90 parts of sawdust, 10-15 parts of magnesium oxide, 5-10 parts of magnesium chloride, 1-2 parts of over 85% of concentrated sulphuric acid and 1-2 parts of paraffin. The preparation method includes sorting, hot grinding, drying, mixing, pavement and hot forming. The environment-friendly building material can replace materials such as medium density fiberboards and three-ply boards and has superior performance.
Description
Technical field
The present invention relates to building material field, relate to a kind of environmental protection building material and preparation method thereof particularly.
Background technology
MDF is that density board is a kind of, is raw material with wood fibre or other plant fiber, through smash, fiber separation, dry after-applied urea-formaldehyde resin or other tackiness agent that is suitable for, a kind of artificial board of after hot pressing, processing again.Generally in 0.5-0.8 grams per cubic centimter scope, thickness is generally the 3-30 millimeter to its density.The wad homogeneous microstructure, interfibrous bonding strength is high, so its MOR, plane tensile strength, modulus of elasticity are good.It is strong to hold screw power geometric ratio shaving board; The wad surfacing, smooth, be convenient to finishing materials such as gluing plane system veneer and tissue paper, and be convenient to cover with paint, lacquer, colour wash, etc. and practice thrift coating; Medium density fibre board (MDF) can produce from several millimeters to tens mm thick sheet materials, can replace plank, the square bar of any thickness, and have the favorable mechanical processing characteristics.Therefore, MDF has obtained using widely.Yet the dependence formaldehyde of part MDF is bonding, though can eliminate formaldehyde through hanging sheet material later, the content of the formaldehyde of some products is still very high, and is also very big to people's health harm.In addition, wear into fiber, changed the structure of timber fully, so moisture absorption, water absorbing properties, thickness swelling are higher because MDF is a log.Therefore, its environment for use has restriction.
The plate of mainly making by inorganic materials; Glass magnesium plate for example, its staple is Natural manganese dioxide and magnesium chloride (more than at least 60%), when atmospheric moisture is big; The surface of plate absorbs airborne moisture and produces surface moisture; And then overwork the globule, even the globule occurs and join together and form trickling phenomenon, phenomenon that Here it is so-called " returning halogen "; When the atmospheric moisture step-down, product surface moisture correspondingly evaporates, and staying full of stains or spots white mark is so-called scum.Return halogen, scum is the great mass defect of magnesian product, can cause and reduce intensity and waterproof moisture-proof characteristic; Influence decorate properties, cause finishing material to come off; Influence outward appearance.
Summary of the invention
The object of the present invention is to provide a kind of building materials, to solve the problems referred to above that exist in the prior art.
Technical scheme provided by the invention is following:
A kind of building materials, by weight, mainly be prepared from following composition:
Sawdust 70-90 part; Natural manganese dioxide 10-15 part;
Magnesium chloride 5-10 part; Vitriol oil 1-2 part more than 85%; And
Paraffin 1-2 part.
In preferred embodiment of the present invention, the water ratio of said sawdust is lower than 10%.
In preferred embodiment of the present invention, the water ratio of said sawdust is 8-10%.
A kind of preparation method of building materials comprises the steps:
(1) sawdust is selected materials;
(2) defibrator process;
(3) drying: adopt dryer that the water cut of sawdust is reduced to water cut and be lower than 10%;
(4) mix: dried sawdust 70-90 part; Natural manganese dioxide 10-15 part; Magnesium chloride 5-10 part; Add concentration vitriol oil 1-2 part more than 85%, the vitriol oil mixes earlier with Natural manganese dioxide and magnesium chloride, mixes with sawdust again, adds paraffin 1-2 part again, and mixer mixing stirs;
(5) mat formation;
(6) hot-forming.
In preferred embodiment of the present invention, the mixing tank rotating speed of step (4) is 1000-5000r.
In preferred embodiment of the present invention, the mixing temperature of step (4) is controlled at 15-35 degree.
In preferred embodiment of the present invention, the hot-forming temperature of step (6) is 180-200 ℃, and pressure is that pressure is 1500-2300T.
Sawdust of the present invention can be from Furniture Factory's tankage, wood-working factory etc.
In the present invention, sawdust is a base-material; Natural manganese dioxide and magnesium chloride be as the gummed effect, replaces tackiness agent such as formaldehyde and have anti-fire action; Sulfuric acid can prevent " returning halogen " phenomenon; Paraffin plays waterproof action.After comprehensive, product do not have " returning halogen ", " scum " phenomenon, waterproof, fire prevention, anticorrosion, mothproof, formaldehydeless volatilization, heat insulation, soundproof effect is strong, resistance to compression is resisting and is surpassing national standard.Product of the present invention can replace materials such as MDF, three-ply-wood, can be used as building materials such as timber floor, partition plate, window frame, door-plate and furniture and uses plate.Product can bore, can follow closely, be prone to that cutting, surface layer can be painted, the veneer performance is good.
Embodiment
Embodiment 1
80 parts in sawdust; 12 parts in Natural manganese dioxide;
8 parts in magnesium chloride; 1.5 parts of the vitriol oils more than 85%; And
1.5 parts in paraffin.
(1) selects materials: sawdust
(2) defibrator process: adopt defibrator to carry out, be current techique, operate identical with MDF;
(3) drying: sawdust is dried to the about 8-10% of water cut;
