Abstract
A fiber-reinforced melamine foam board comprises, by mass, 5% to 15% of fibers and 85% to 95% of melamine foam. The porosity of the fiber-reinforced melamine foam board ranges from 75% to 94%, the diameter of the fibers ranges from 0.1 micrometer to 1 micrometer, and the length of the fibers ranges from 0.5 mm to 2.5 mm. The material is one of glass fibers, quartz fibers and basalt fibers. The density of the melamine foam ranges from 5.0 kg/m<3> to 16.5 kg/m<3>. The fiber-reinforced melamine foam board has the beneficial effects that a fiber-reinforced structure is adopted, so that the tenacity, the bending strength and the flame-retardant performance of foam are greatly improved, and the application field is broadened; compared with a laminated board reinforcing manner, the layer shearing force of the foam board is greatly increased; cutting can be performed again according to different use conditions, the flame-retardant performance and the mechanical performance of the foam board cannot be affected, and use is convenient.
Description
Technical field
The present invention relates to foam plate technical field, especially a kind of fiber reinforcement melamine foamed plastic plate.
Background technique
Melamine foamed plastic, belong to the organic flexible foam product of macromolecule, as the new chemical materials of a kind of low density, fire-retardant, sound-absorbing, in the field such as civilian, industrial, building, traffic, aviation, military affairs, daily, electronic information, there is very important using value, be particularly suitable for using under the environmental conditions having fire-retardant, high temperature, Di Frequency noise absorption to require, become the Novel environment-friendlymaterial material that 21 century has great development prospect.
But melamine foamed plastic is a kind of foamed material of fragility, its toughness and resistance to flexure poor, easily in actual applications because of External Force Acting, embrittlement occurs, the also easy imbalance because of weight or natural compression and cause warpage in using process, brings difficulty and hidden danger to construction.
Publication No. is the Chinese patent of CN201649322U; application discloses that above a kind of phenolic glass fiber enhancement foam composite layer, distinguish the foam composite board of combined strength bination protective layer below, described phenolic glass fiber enhancement foam composite layer is composited by phenol formaldehyde foam and glass fibre.This model utility composite sheet can be used for the laminated heat-preserving of aircraft, boats and ships, vehicle, also can in the strict place of the fire protection requirement such as tunnel, oil well as body of wall, stifled hole, also can be used as environmental protection, insulation, soundproof material for civil building, is the thermal insulating composite panel of high strength.
Publication No. is the Chinese patent of CN202416611U, proposes the enhancement mode foam heat-insulating board that a kind of at least one deck fleece enhancement layer is positioned at the internal layer of foam.The warming plate of this model utility, by increasing fleece reinforcing material in the inside of foam board, intensity increases, and reduces the damage percentage of foam plate during construction, effectively can suppress the warpage of warming plate, expanded the application of heat preservation plate material.
Summary of the invention
The object of the invention is to overcome existing foamed material, to strengthen effect bad, and foam are easily crisp, the caducous problem of enhancement layer, provides a kind of fire-retardant, fiber reinforcement melamine foamed plastic plate that intensity is good.
For realizing object of the present invention, the technological scheme adopted is: a kind of fibre-reinforced melamine foamed plastic plate, comprise the fiber of 5% ~ 15% quality and the melamine foamed plastic of 85% ~ 95% quality, the porosity ratio of melamine foamed plastic plate is 75 ~ 94%, described fiber diameter is 0.1 ~ 1 μm, and length of staple is 0.5mm ~ 2.5mm; Material is the one in glass fibre, quartz fibre, basalt fibre, and described melamine foamed plastic density is 5.0 ~ 16.5kg/m
3.
Described fiber reinforcement melamine foamed plastic plate, it is characterized in that described melamine foamed plastic comprises each raw material of following weight portion: the melamino-formaldehyde precondensate 95 ~ 150 parts that the equal molecular mass of number is 1800 ~ 3700, viscosity is 1800 ~ 3500mPas, 0.2 ~ 3 part, surface active agent, stabilizer 30 ~ 45 parts, 2 ~ 9 parts, curing agent, deionized water 14 ~ 55 parts.
Melamine in described melamino-formaldehyde precondensate and the mol ratio of formaldehyde are 1:1.8 ~ 3.6, described surface active agent is ethylene oxide, described stabilizer is a kind of in isobutane or pentane or both mixing, and described curing agent is p-methyl benzenesulfonic acid.
The beneficial effect that the present invention has is: 1. adopt fiber reinforcing texture, foam toughness, resistance to flexure, flame retardant property is greatly improved, has widened application; 2. the mode that strengthens compared with laminate of this foam plate, layer shearing force improves greatly; 3. can carry out cutting process again according to the difference of service condition, its fire-retardant and mechanical property can not be affected, easy to use.
Embodiment
Below in conjunction with specific embodiment, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims and limited.
embodiment 1
A kind of fiber reinforcement melamine foamed plastic plate, comprise the fiber of 15% quality and the melamine foamed plastic of 85% quality, it is characterized in that described fiber diameter is 0.6 μm, length of staple is 1mm, the porosity ratio of melamine foamed plastic plate is 95%, material is glass fibre, and described melamine foamed plastic density is 5.0kg/m
3.
Processing method: glass fibre is loaded and has in the machine laminated into type of cavity, start mobile pouring machine to glass fibre upper foaming melamine formaldehyde resin, charging equipment after starting, glass fibre is spilt on Foamex upper berth, heating in laminater, foaming, mixing, slaking, laminater rear portion out time can obtain fiber reinforcement melamine foamed plastic plate, can deburring as required, cutting.
Above are only single embodiment of the present invention, but design concept of the present invention is not limited thereto, all changes utilizing this design the present invention to be carried out to unsubstantiality, all should belong to the behavior of invading the scope of protection of the invention.In every case be the content not departing from technical solution of the present invention, any type of simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present invention, still belong to the protection domain of technical solution of the present invention.
