Description

Technical Field

[0001] The invention relates to the technical field of flooring, in particular to a soundproof flooring and a processing technology of the soundproof flooring. Background Art

[0002] With the accelerated pace of modern life and the increasing requirements of people for living environment, soundproof flooring, as a floor decoration material that can effectively reduce noise interference and improve living comfort, has gradually been favored by the market. The design of soundproof flooring aims to achieve good sound insulation and noise reduction effects through a specific structure and material combination, while maintaining the beauty and durability of the flooring.

[0003] Traditional soundproof flooring is mostly made of wood materials such as plywood, high-density fiberboard and particleboard, and then a soundproof layer is set on the base layer to absorb and isolate noise. At present, common soundproof layer materials on the market include polyurethane foam, rubber particles, mineral wool, etc. Although these materials have certain sound-absorbing properties, they still have some shortcomings in practical applications. For example, although polyurethane foam has good sound absorption effect, it has low hardness and is easy to deform after long-term use; rubber particles may have environmental problems and limited sound absorption performance; although mineral wool materials have excellent sound absorption performance, they are expensive and difficult to process and shape. It can be seen that we urgently need a soundproof floor and a soundproof floor processing technology. Summary of the invention

[0004] In view of the above technical deficiencies, the purpose of the present invention is to provide a soundproof floor and a soundproof floor processing technology. A new type of soundproof floor is provided which adopts a multi-layer microporous sound-absorbing material formed by mixing polyurethane foam and nano-silicon dioxide particles in a specific proportion as the soundproof layer. This material combines the good sound absorption performance of polyurethane foam and the high hardness and high stability characteristics of nano-silicon dioxide particles. It is made into a multi-layer microporous structure through a special process, which can effectively absorb sound waves and reduce the propagation and reflection of noise. At the same time, the material also has high hardness and durability, can resist deformation and damage during long-term use, and improve the stability and service life of the floor.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a soundproof floor, comprising a base layer, a soundproof layer is arranged on the top of the base layer, a decorative layer is arranged on the top of the soundproof layer, and a wear-resistant layer is arranged on the top of the decorative layer.

[0006] Preferably, the base layer is configured as a high-density fiberboard or particle board, the sound-absorbing layer is configured as a plurality of layers of microporous sound-absorbing materials stacked together, the decorative layer is configured as a simulated wood grain or stone grain PVC film, and the wear-resistant layer is configured as a transparent high-hardness PVC film.

[0007] Preferably, the sound-proof layer material is formed by mixing polyurethane foam and nano-silicon dioxide particles in a specific ratio, and the ratio of the polyurethane foam to the nano-silicon dioxide particles is 50:1 to 80:1.

[0008] A silent floor processing process comprises the following steps:

[0009] S1, the base layer is made of high-density fiberboard with a size of 1200mm×200mm×8mm. Use a brush, roller or sprayer to evenly apply the waterproofing agent on the surface of the base layer, so that the waterproofing agent can fully penetrate into the base layer to form an effective waterproof layer. After applying, let the base material dry naturally to ensure that the waterproofing agent is completely cured;

[0010] S2, the sound-absorbing layer is made of polyurethane foam and nano-silicon dioxide particles in a ratio of 50:1 to 80:1, and is made into a multi-layer microporous sound-absorbing material through a special process, with a total thickness of 2mm

[0011] S3, the decorative layer is made of simulated oak grain PVC film with a thickness of 0.5mm, and the wear-resistant layer is made of transparent high-hardness PVC film with a thickness of 0.2mm;

[0012] S4, stacking the pretreated base layer, the mute layer, the decorative layer and the wear-resistant layer in order, sending them into a hot press, keeping them at a temperature of 160° C. to 190° C. and a pressure of 0.7 MPa to 5 MPa for 10 minutes, and performing one-time composite molding;

[0013] S5, uses environmentally friendly hot melt adhesive to seal, ensuring edge strength and moisture resistance;

[0014] S6, UV curing treatment is performed on the surface of the wear-resistant layer to improve wear resistance and glossiness.

[0015] Preferably, in step S1, the amount of waterproofing agent applied is about 200-300 grams per square meter to ensure that the waterproofing agent fully penetrates, and the natural drying time is 24-48 hours.

[0016] Preferably, in step S2, the polyurethane foam and nano-silica particles are uniformly mixed, the mixed material is injected into a mold, and the hot pressing molding technology is used. The temperature of the hot press is set to 150°C, the pressure of the hot press is set to 0.8MPa-5MPa, and the hot pressing state is maintained for 5 minutes. After hot pressing, the temperature of the curing furnace is set to 120°C and the time is set to 10 hours to cure the material below the molding temperature to avoid overheating and decomposition of the material, ensure that the material is fully cured inside and reaches a stable state, and then naturally cool to room temperature to avoid excessive internal stress or cracking of the material caused by rapid cooling, thereby forming a sound-absorbing material with a multi-layer microporous structure. The tight multi-layer microporous structure is not only conducive to the absorption and dissipation of sound waves, but also can improve the overall strength of the material, making it have better stability and durability.

[0017] Preferably, in step S3, a flatness detector is used to detect whether the surface of the decorative layer is flat, and a laser scratch tester is used to detect whether the surface of the decorative layer has no scratches.

[0018] Through the above technical solution, the surface of the decorative layer is tested by a flatness tester and a laser scratch tester, which can ensure product quality and improve production efficiency.

[0019] Preferably, in step S5, EVA hot melt adhesive or PUR hot melt adhesive is selected, and a hot melt adhesive gun is used to evenly apply the hot melt adhesive on the edge of the floor.

[0020] Through the above technical solution, by applying hot melt adhesive to the edge of the floor, the various parts of the floor can be effectively fixed to prevent the floor from loosening or deforming during use, and the sealing of the edge of the floor can be enhanced to prevent moisture, dust and other impurities from entering the interior of the floor, thereby extending the service life of the floor.

[0021] Preferably, in step S6, the composite-formed floor is sent to a UV curing device, and the UV curing device is a UV curing oven or a UV curing machine, and the light source is adjusted to 20 mW / cm 2 The curing time is set to 8 minutes, the equipment temperature is set to room temperature to 60°C, and the wear-resistant layer is cured by uniformly conveying it through a conveyor belt.

[0022] Through the above technical solution, by adjusting the light source intensity to 20mW / cm2 and setting the curing time to 8 minutes, it can be ensured that the wear-resistant layer is quickly cured in a short time, thereby improving production efficiency. At the same time, the resin or other coating on the surface of the wear-resistant layer undergoes a chemical reaction under the irradiation of ultraviolet rays to form a tighter and stronger structure. The floor is transported at a uniform speed by a conveyor belt, which can ensure that the wear-resistant layer is uniformly illuminated and cured in the UV curing equipment, which helps to avoid performance differences and appearance problems caused by uneven curing.

[0023] Preferably, in step S4, when the base layer, the sound-proof layer, the decorative layer and the wear-resistant layer are stacked in sequence, a scraper is used to gently scrape each layer flat to ensure that no bubbles are generated, and the material is preheated to a temperature close to the hot pressing temperature.

[0024] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0025] First, the present invention uniformly mixes polyurethane foam and nano-silicon dioxide particles, injects the mixed material into a mold, and uses hot pressing molding technology. The temperature of the hot press is set to 150°C, the pressure of the hot press is set to 0.8MPa-5MPa, and the hot pressing state is maintained for 5 minutes. After hot pressing molding, the temperature of the curing furnace is set to 120°C and the time is set to 10 hours to cure the material below the molding temperature to avoid overheating and decomposition of the material, ensure that the material is fully cured inside and reaches a stable state, and then naturally cool to room temperature to avoid excessive internal stress or cracking of the material caused by rapid cooling, thereby forming a sound-absorbing material with a multi-layer microporous structure. The compact multi-layer microporous structure is not only conducive to the absorption and dissipation of sound waves, but also can improve the overall strength of the material, making it have better stability and durability.

[0026] Second, the present invention uses a brush, roller or sprayer to evenly apply the waterproofing agent on the surface of the base layer, and the application amount is controlled at about 200-300 grams per square meter to ensure that the waterproofing agent can fully penetrate into the base layer to form an effective waterproof layer. The natural drying time is 24-48 hours to ensure that the waterproofing agent is completely cured, thereby improving the moisture-proof performance of the floor and extending its service life.

[0027] Third, the present invention uses a hot melt glue gun to evenly apply hot melt glue on the edge of the floor to ensure edge strength and moisture-proof performance. Then, through a UV curing furnace or UV curing machine, the light source is adjusted to 20mW / cm2, the curing time is set to 8 minutes, the equipment temperature is set to room temperature to 60°C, and the wear-resistant layer is cured by uniformly conveying it through a conveyor belt, which promotes close bonding between the layers and improves the overall strength of the floor.
