Description
Technical field
The present invention relates to a kind of PLASTIC LAMINATED, particularly a kind of halogen-free A 2 grade fireproof plate.
Background technology
PLASTIC LAMINATED has another name called refractory slab, formal name used at school is thermosetting resin-impregnated paper high-pressure laminated board, english abbreviation is that HPL{Decorative high-Pressure Laminate} is the surface decoration refractory building material, abundant surface color and polish is arranged, lines and special logistics performance are widely used in the fields such as upholstery, furniture, kitchen cabinet, laboratory table face, exterior wall.PLASTIC LAMINATED is the impregnation technology of body paper (titanium valve paper, kraft paper) process trimeric cyanamide and resol, and High Temperature High Pressure becomes.
Based on the fire accident that in the market Highrise buildings and public place occur in succession, people have recognized the importance of the security against fire of material of construction.Departments of government has also been put into effect and has a series ofly been used the law must possess corresponding fire-protection rating and performance, rules about material of construction.General material of construction fire rating is comprised of A level and B level, B level class fire-proof product, and from conventional meaning, it is not reach real flameproof effect.It just in the product of routine, has added some fire retardants, improves the point of ignition of its product self, still can burn when temperature reaches its point of ignition.Relatively mix the genuine with the fictitious in view of existing market, the price that has is very expensive, and have on fire rating, be difficult to the rank and the performance that reach desirable.So, for this market, be faced with severe technology test and huge market potential.
Summary of the invention
The invention provides a kind of halogen-free A 2 grade fireproof plate, purpose is to solve the prior art problem, and a kind of PLASTIC LAMINATED with good fire resistance is provided.
The present invention's technical scheme that adopts of dealing with problems is:
Halogen-free A 2 grade fireproof plate, described PLASTIC LAMINATED comprises following component by weight
Preferred 80 orders of described quartz sand and 120 purpose quartz sand mixtures, wherein the parts by weight that account in whole PLASTIC LAMINATED of 80 order quartz sands are 80-90, the parts by weight that 120 order quartz sands account in whole PLASTIC LAMINATED are 5-10.
Preferred 80 orders of described brucite and 100 purpose brucite mixtures, wherein the parts by weight that account in whole PLASTIC LAMINATED of 80 order brucites are 30-35, the parts by weight that 100 order brucites account in whole PLASTIC LAMINATED are 20-25.
Described water-resisting agent is the polymer water-resisting agent.
Described defoamer is the inorganic silicon defoamer.
Described staple fibre is staple glass fibre, and staple glass fibre is long to be 20mm-35mm.
Quartz sand of the present invention is a kind of nonmetallic mineral, is a kind of silicate minerals of hard, wear-resisting, stable chemical performance, and its essential mineral composition is SiO2, and hardness is 7, its major ingredient except silicon-dioxide and, also contain ferric oxide, clay, mica.So in the present invention, allocating into of this material effectively utilized the ceramic characteristics of silicon-dioxide in the quartz sand, makes sample reach other stability of A2 level fully on fire resistance.
Brucite of the present invention, molecular formula: Mg (OH)
2, be a kind of natural mineral that is rich in crystal water, Mg (OH)
2Have fire-retardant, press down cigarette, fill three functions, be the fire-retardant raw material that gains great popularity.
Light calcium carbonate of the present invention (Light Calcium Carbonate) claims again precipitated chalk (Precipitated Calcium Carbonate is called for short PCC).Because its sedimentation body (2.4-2.8mL/g) is larger than the water-ground limestone settling volume (1.1-1.9mL/g) of producing with mechanical means, therefore be called as light calcium carbonate.Among the present invention, this material strengthens the tensile strength wear resistance, tear strength as a kind of weighting agent.Also greatly improved simultaneously the product denseness.
Perlite of the present invention (Perlite) is a kind of acidic lava of volcanic eruption, and perlite becomes a kind of lightweight, multifunctional novel shaped material through expansion.Have that apparent density is light, thermal conductivity is low, chemical stability is good, the use temperature scope is wide, wettability power is little, and the characteristics such as nontoxic, tasteless, fire prevention, sound-absorbing.
Silicon-dioxide of the present invention claims again silica, chemical formula SiO
2SiO
2The bond energy of middle Si-O key is very high, fusing point, boiling point higher (1723 ℃ of fusing points, 2230 ℃ of boiling points).After repetition test, find, add the silicon-dioxide of certain deal, effectively reduce the combustion heat value of sample, and the interpolation of process silicon-dioxide, improved greatly the smooth of specimen surface, smooth.In halogen-free A 2 grade fireproof plate of the present invention, the fire retardant that aluminium hydroxide and trimeric cyanamide form according to specific ratio grouping.Through test and demonstration repeatedly, find the above-described fire retardant that forms according to specific cluster, its flameproof effect significantly is superior to monomer to be added or other compositions.
Staple fibre described in the present invention, it act as and strengthens the existence of sample product tensile strength purpose, and preferred length is the glass fibre of 20mm-35mm.Glass fibre (glass fiber or fiberglass) is a kind of ceramic of excellent performance, and is of a great variety, and advantage is that good insulating, thermotolerance are strong, erosion resistance good, and physical strength is high, but shortcoming is that property is crisp, and wear resistance is relatively poor.
Described acrylic latex is the special-purpose sizing agent of selected sample PLASTIC LAMINATED.
Water-resisting agent of the present invention, defoamer and H
2O as auxiliary composition, in prescription of the present invention, plays auxiliary PLASTIC LAMINATED moulding additive, does not destroy the ancillary additions of its fire resistance and effect.Wherein water-resisting agent adopts the polymer water-resisting agent, and the polymer water-resisting agent is a kind of high performance polymer material.Water impermeability is good, and cohesive force is strong, and ageing-resistant, corrosion resistance nature is nonpoisonous and tasteless, is green building productions.Defoamer adopts the inorganic silicon defoamer, and the inorganic silicon defoamer has very strong disappearing to moisture content and presses down the bubble effect, can remove rapidly the trickle bubble of carrying secretly between fiber, eliminate simultaneously the bulla of the water surface, eliminate bubble to the impact of technique, avoid the formation of hole, avoid the cracking phenomena of sheet material.
To the selection of quartz sand and brucite order number, if the order number of selecting is excessive, intensity has reached, and snappiness is very poor, and sheet material is easy to be fractureed; If the order number of selecting is too small, the processing requirement of production is very high, and on the intensity of sheet material, does not reach again certain technical requirements.So, through test of many times and investigation, preferred 80 orders of the quartz sand among the present invention and two kinds of quartz sands of 120 orders and 80 orders and two kinds of brucites of 100 orders can make sheet material both reach certain intensity, guarantee again its this snappiness of having, it can be constructed as follows the PLASTIC LAMINATED of several prescriptions:
1.
2.
3.
Beneficial effect of the present invention: owing to contain quartz sand and brucite among the present invention, make the PLASTIC LAMINATED of making have good fire line.And add the silicon-dioxide of certain deal, effectively reduce the combustion heat value of sample, and the interpolation of process silicon-dioxide, improved greatly the smooth of specimen surface, smooth.In halogen-free A 2 grade fireproof plate of the present invention, the fire retardant that aluminium hydroxide and trimeric cyanamide form according to specific ratio grouping.Through test and demonstration repeatedly, find the above-described fire retardant that forms according to specific cluster, its flameproof effect significantly is superior to monomer to be added or other compositions.
