Description
Technical field
The present invention relates to decorative panels, and in particular to a kind of magnesium oxysulfide fancy veneer and preparation method thereof.
Background technique
At the end of the 19th century, various countries start to do internal partition wall with plasterboard, cement fibrolite plate, are that yield is larger in the world and answers for one kind
With wide light-weight building ornament materials, this partition wall generallys use steel rough ground and does skeleton, and according to requirements, is equipped with
Other materials (such as mineral wool board, water-repellent paint and decoration plane material) composition, the partition wall for thering is sound insulation or advanced finishing to require.20th century
The seventies, China starts to test Thistle board and produced, and applies in building decoration engineering, and magnesium oxysulfide concrete
Plate is that China started the board for being employed for building decoration partition plate and decorative plate of outer wall at 2015 or so.
On architectural ornament market now, the application of plasterboard, cement fibrolite plate, magnesium oxysulfide concrete plate etc. is more universal, but
All respectively there is disadvantage.Because plasterboard main material is gypsum basis, it is difficult to be made into partition post gap, easy to crack, fragile to undermine
Nail-holding ability is poor, and there are natural defects in waterproof performance.Equally, using magnesium oxysulfide as the magnesium oxysulfide concrete plate of main material in shrinking percentage and
Low temperature drying environment, especially in northern China, it may appear that contraction distortion seam is easy cracking, and density is high, and Unit Weight is high, fortune
It is defeated at high cost, it is difficult to install.
Summary of the invention
In order to overcome drawbacks described above, the present invention provides a kind of preparation method of magnesium oxysulfide fancy veneer, passes through party's legal system
It is standby go out magnesium oxysulfide thin plate have that fire prevention, waterproof performance are high, nail-holding ability is strong, ungauged regions, seam should not crack, not easy to break have
Imitate effect.
The present invention is to solve technical solution used by its technical problem:
A kind of preparation method of magnesium oxysulfide fancy veneer, includes the following steps:
Step 1: by the raw material of following components and parts by weight the magnesium oxysulfide fancy veneer: magnesia: 50~60 parts,
Magnesium sulfate aqua: 50~60 parts, foaming agent: 4~5 parts, bamboo fibre: 20~25 parts, water: 50~60 parts and modifying agent: 0.5~1
Part；
Step 2: first stirring: by magnesium sulfate aqua, magnesia, bamboo fibre, water, modifying agent and the half of formula ratio
The foaming agent of formula ratio, which is placed in mixing plant, to be stirred；
Step 3: physical blowing: remaining foaming agent is added in Intermittert prefoaming machine, is carried out in Intermittert prefoaming machine
Heating, foaming；
Step 4: it is again stirring for: foamed good foaming agent being added in the blender in step 2, after foaming
Foaming agent is stirred evenly with the mixture in blender；
Step 5: molding: it is laid with one layer of fire retardant nonwoven fabric in the bottom of hopper, the material being stirred in step 4 is poured into
In hopper, and one layer of fire retardant nonwoven fabric is spread above material, roll one-pass molding above with rolling wheel；
Step 6: solidification: molding plate is placed and carries out nature in constant-temperature house and is fixed to and is completely dried to get magnesium oxysulfide
Fancy veneer；
Step 7: trimming: magnesium oxysulfide fancy veneer is cut using cutting machine, cut lengths should meet next procedure
Requirement, the leftover pieces of cutting, which come back in preparation process, to be recycled.
Preferably, in step 6, the temperature of constant-temperature house is 25 DEG C, and the temperature of constant-temperature house is kept using steam heating.
Preferably, the foaming agent is flame retardant type foaming EPS particle, into the fire-retardant of Intermittert prefoaming machine in step 3
The diameter of type foaming EPS particle is 0.001~0.005mm.
Preferably, the specific process of step 3 is, foaming agent is injected in Intermittert prefoaming machine, and by temperature in prefoaming machine
80 DEG C~120 DEG C are heated to, foaming agent foams in prefoaming machine, until when the diameter of blowing-agent particle reaches 1.5~2mm
Stop foaming, finally stirs evenly.
Preferably, the modifying agent is at least one of citric acid, oxalic acid, calcium dihydrogen phosphate and phosphoric acid.
Preferably, the magnesia is magnesite light burnt powder.
Preferably, the bamboo fibre is fire-retardant bamboo fibre, fire-retardant by obtaining after impregnating in bamboo fibre immersion fire retardant
Bamboo fibre.
The present invention also provides a kind of magnesium oxysulfide fancy veneers, are processed using the preparation method of above-mentioned magnesium oxysulfide fancy veneer
It forms.
Preferably, the thin plate includes plate core and the fire retardant nonwoven fabric positioned at plate core two sides, and the raw material of the plate core includes
Magnesia, magnesium sulfate, foaming agent, bamboo fibre, water and modifying agent.
The beneficial effects of the present invention are:
1) for this magnesium oxysulfide thin plate compared with the plasterboard of same thickness, fire endurance is 2-3 times of plasterboard, fire prevention
Performance reaches A1 grades；And because the present invention will not generate when meeting fire without pasting one layer of paper clad can as conventional gypsum plate surface
Any flue gas, smoke toxicity can reach national highest level AQ1 grades；
2) waterproof performance of the present invention is good, or even can impregnate in water, and softening will not be deformed after natural air drying, will not change strong
Degree, and traditional plasterboard does not have waterproof performance, though there is waterproof paper waterproof gypsum board, only surface is played certain waterproof and is made
With substrate or gypsum, meeting water can soften, so plasterboard can not be applied to the partition wall of the wet environments such as bathroom；
3) this magnesium oxysulfide thin plate shrinking percentage is low and easy joint treatment, because being added to fire-retardant EPS particle in the present invention, so receiving
Shrinkage is very small almost nil, and reduces the weight of plate；And it is highly stable after joint treatment, it will not cracking, transport
Be easily installed, conveniently, solve the problems, such as the shrinkage cracking and unit weight of traditional cement fibrolite plate and magnesium oxysulfide concrete plate
Measure higher problem；
4) nail-holding ability of the invention and flexural strength are significantly better than Thistle board, are 3 times of plasterboard；9.5mm thickness stone
The hoisted load of cream plate is only 7N, average breaking load 400N, and this thin plate hoisted load is >=15N, flexural strength >
16MPa。
Specific embodiment
Below in conjunction with the embodiment of the present invention, technical scheme in the embodiment of the invention is clearly and completely described,
Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based in the present invention
Embodiment, every other embodiment obtained by those of ordinary skill in the art without making creative efforts, all
Belong to the scope of protection of the invention.
A kind of preparation method of magnesium oxysulfide fancy veneer, includes the following steps:
