Description

flameproof material structure

The present invention relates to a flame-proof material structure, in particular to a flame-proof material structure with high fire resistance and cushioning effect, which can be applied to public buildings, long-term care institutions, nurseries, gymnasiums and other places as well as floor mats for home use or cushioning pads.

As people pay more and more attention to the quality of living safety, various cushion materials have been introduced on the market as materials for installing buildings. At the same time, in order to meet the needs of safety such as fire protection, a common method of making fireproof mats is to use a polymer resin as a foam material layer, and add fireproofing agents (also known as flame retardants) to form a fireproofing mat. layer, and then cover the surface of a base material with a fireproof layer to make a fireproof mat, so that it has the effect of flame-proof and flame-retardant; in addition, in order to increase the wear resistance of the fireproof mat, it can be re-coated on the surface of the above-mentioned fireproof layer A wear-resistant layer is covered to enhance the scratch resistance and abrasion resistance of the fireproof mat, improve the durability of the fireproof mat, and prolong the service life.

However, a large amount of fireproofing agent must be added to the fireproof layer of the known fireproof mats in the Taiwan market to achieve a high level of fireproofing effect. However, the technology has a high technical threshold, which makes ordinary fireproof mats unable to achieve Standard for flameproof labels.

Furthermore, even if the technical problem of adding a large amount of fireproofing agent can be overcome, because the total amount of fireproofing agent added is too high, the amount of smoke generated during combustion is relatively large. The amount of smoke generated will increase the cost of making and using fireproof mats by more than 5-10 times, which cannot be practically applied in the market After adding a large amount of fire retardant, the wear resistance of the surface of the fireproof mat will be poor; in addition, such as long-term care institutions, nurseries, gyms and other places, the people who use it are mostly children or the elderly who are prone to injuries and falls. , so the fireproof mat must also be elastic so that it has a cushioning effect, which can reduce the injuries caused by children or the elderly due to collisions or falls.

To sum up, it is necessary to develop a novel fireproof mat to overcome the above-mentioned shortcomings of the conventional fireproof mat.

In view of this, the inventor has been engaged in the manufacture, development and design of related products for many years, aiming at the above shortcomings as the goal of improvement. After detailed design and careful evaluation and testing, he finally obtained a novel flameproof material structure as a fireproof pad material.

The main purpose of the present invention is to provide a flameproof material structure with high fireproof rating and cushioning effect. The flameproof material structure includes: a first resin foam material layer, a first flame retardant layer and a second flame retardant layer. The first flame retardant layer is arranged above the resin foam material layer, the second flame retardant layer is arranged below the resin foam material layer, and the first flame retardant layer and the second The flame retardant layer can be composed of various fireproof materials. In addition, a protective layer can be further separately provided on the surface layers of the first flame retardant layer and the second flame retardant layer.

Wherein, the thickness of the first resin foam material layer may be 5-80mm; and the thickness of the first flame-retardant layer and the second flame-retardant layer may be 0.1-10mm respectively, and the first resin The difference between the thickness of the foam material layer and the thickness of the first flame retardant layer and/or the second flame retardant layer must be more than 5mm. When the thickness of the first resin foam material layer is less than 5 mm, the cushioning property is lacking; and when the thickness is greater than 80 mm, the material cost is too high.

Furthermore, when the thickness of the first flame retardant layer and the second flame retardant layer is less than 0.1 mm, the fire protection is insufficient; and when the thickness is greater than 5 mm, the material cost is too high. In addition, when the difference between the thickness of the first resin foam material layer and the thickness of the first flame retardant layer and/or the second flame retardant layer is less than 5 mm, the same disadvantage of high cost exists.

The first resin foam material layer is composed of a plurality of layers formed by high-power (low-density) resin foam materials, and the high-power (low-density) resin foam material refers to the resin foam material. The expansion ratio is greater than 10 times, and the density is between 20~100kg/ ^m3 . The high-expansion (low density) resin foam material has better elasticity and cushioning effect because of its larger expansion ratio. In addition, the first resin foam layer can also be further composed of a plurality of high-power (low-density) resin foam materials with flame retardants added (flame retardant) or other layers formed by non-resin flame retardant materials. ; The high molecular polymer used in the first resin foam material layer can be selected from ethylene/vinyl acetate copolymer (ethylene vinyl acetate copolymer, EVA), polyvinyl chloride (polyvinyl chloride, PVC), polyethylene (polyethylene , PE), polypropylene (polypropylene, PP), polystyrene (polystyrene, PS), polyamide (polyamide, PA), acrylonitrile-butadiene-styrene copolymer (acrylonitrile butadiene styrene copolymer, ABS) or A combination of any one or more of them, but not limited thereto, any high molecular polymer commonly used as a foaming material can be used.

The above flame retardant can be selected from decabromodiphenylethane, decabromodiphenyl ether, antimony trioxide, zinc borate, aluminum hydroxide, magnesium hydroxide, ammonium polyphosphate, titanate compound, polymer silicon compound Or a combination of any one or more of them, but not limited thereto, any organic compound or inorganic compound commonly used as a flame retardant can be used; other non-resin flame retardant materials can be aluminum foil, metal woven cloth, glass fiber Any one of cloth, but not limited to, any non-resin material commonly used as flame retardant can be used.

The first flame retardant layer and the second flame retardant layer can be composed of various fire retardant materials, and the first flame retardant layer and the second flame retardant layer can be composed of the same or different fire retardant materials; for example In other words, fireproof materials can be metal films/sheets, halogenated fireproof compounds/films, or fireproof coatings.

Wherein, the metal film/sheet can specifically be aluminum foil, copper film, copper fiber, etc.; the halogen fireproof compound/film can be polyvinyl chloride (PVC), fluorine resin film or a combination thereof; the fireproof coating is It is composed of colloidal or resinous materials as the carrier, and at least one kind of fireproof powder will be added.

The colloid or resin material used as the carrier of the fire retardant coating refers to an object or resin that can be cured after being liquid or pasty at room temperature or low temperature, cooling, UV light irradiation, or aging time; for example, the The carrier of the fire retardant coating can be glue, resin, paste, elastomer, paint or a combination thereof such as water-based/oil-based fluorocarbon resin, water-based/oil-based epoxy resin, neoprene, etc. Among them, the resin system has a melt index (Melt Flow Index, MI) of 10 or more (unit: g/10min). Generally, the MI value of commonly used resins is between 1 and 25, and the larger the MI value, it represents the viscosity of the resin raw material. And the smaller the molecular weight, the better the fluidity. On the contrary, the higher the viscosity and molecular weight of the resin material, the worse the fluidity. Resins with an MI value of 10 or more can be ExxonMobile's Vistamaxx series products. The elastic system refers to an elastomer that can be softened at low temperature, especially an elastomer with a softening temperature below 80°C, specifically Mitsui Chemicals' thermoplastic elastomer POE series products. In addition, you can also use commercially available fireproof paint to add fireproof powder to enhance the fireproof effect, such as PROMAT, JOLYPATE and other paints.

In addition, the fireproof powder can be roughly divided into the following types: 1. Phosphorus-based and bromine-based fireproofing agents: can generate inert gas, block oxygen, and inhibit combustion. Generally, antimony trioxide (Sb ₂ O ₃ ) or Bismuth trioxide (Bi ₂ O ₃ ) is used as an additive, specifically brominated polystyrene, polytetrafluoroethylene (Teflon); 2. Zinc borate; 3. Chlorinated paraffin; 4. Metal particles /Flakes/fibers, minerals, inorganic powders, metal oxides, compounds containing crystal water, specifically Al(OH) ₃ , Mg(OH) ₂ ; 5. Intumescent flame retardants, specifically intumescent Activated carbon, which can form an expanded carbon layer when absorbed with flames to prevent flames from spreading; 6. Phosphorus-based microcapsules, specifically microcapsule-coated red phosphorus fireproof masterbatch; 7. Organic synthetic fireproofing agents, such as titanate , Polymer-based synthetics, phospholipid synthetics, etc.

Wherein, based on the total weight of the fireproof coating, the content of the carrier can be 20-95%, and the content of the fireproof powder can be 5-80%.

Wherein, based on the total weight of the first resin foam material layer, the weight percentage content of the high-power (low density) resin foam material is 70% to 100%; and the flame retardant or other non-resin flame retardant materials The weight percentage content is 0~30%.

The protective layer is used to protect the first flame retardant layer and/or the second flame retardant layer, because the wear resistance of the surface layer of the first flame retardant layer and/or the second flame retardant layer is poor , leading to a decrease in durability, so a protective layer is used to cover the surface of the first flame-retardant layer and/or the second flame-retardant layer to increase the wear resistance; the wear-resistant material used in the protective layer can be High molecular polymers, such as PE, EVA, PVC or any combination thereof, but not limited thereto, any common wear-resistant and scratch-resistant materials can be used.

On the other hand, when the fireproof mat used in some places must have a greater thickness to enhance the cushioning effect, for example, a gymnasium needs a thicker fireproof mat as a floor mat due to the heavy weight of fitness equipment, the said fireproof The flame material structure can be composed of multiple layers to achieve the required hardness and elasticity.

The above-mentioned multi-layer stacking method, from top to bottom, can be the first flame-retardant layer, the resin foam material layer, the second flame-retardant layer, the second resin foam material layer, and the sandwich sandwich of the third flame-retardant layer Composition of the flameproof material structure, but not limited thereto; therefore, more layers of the flameproof material can be stacked sequentially according to the above arrangement Flame material structure, and the surface layer of the flame retardant layer located on the uppermost layer and/or the lowermost layer is individually provided with a protective layer to increase the wear resistance.

The first flame retardant layer and the second flame retardant layer of the present invention must at least pass the HF-1 grade flame retardant standard when they are tested by the plastic flammability standard UL94 issued by Underwriters Laboratories of the United States; preferably, The first flame retardant layer and the second flame retardant layer of the present invention can reach the flame retardant standard of V0 grade.

The flammability standard of UL94 is to classify the flame retardant grades according to the burning conditions of plastics of different thicknesses. From the lowest (minimum flame retardancy) to the highest (maximum flame retardancy) flame retardancy grades can be roughly divided into HB, V2, V1, V0, 5VB, and 5VA; and the flame retardancy grades of high-power (low-density) resin foam materials can be roughly divided into HF-1, HF-2, and HBF in sequence. Among them, the test generally uses a 5-inch by 0.5-inch sample; for the 5VA and 5VB standards, strip and sheet samples are tested, and the intensity of the flame is about five times that used to test other materials . The definitions of various classification standards can be shown in Table 1 below.
