Description

Technical Field

[0001] The invention relates to the technical field of green and healthy buildings, in particular to a nano-modified GPS flexible thermal insulation and sound insulation pad floor thermal insulation and sound insulation system. Background Art

[0002] The existing sound insulation pads have no thermal insulation performance, poor environmental protection or fire resistance, and need to be used together with insulation boards, which increases the construction difficulty and system complexity. At the same time, in order to achieve the sound insulation effect, the existing sound insulation pads mostly use softer materials for sound insulation and vibration reduction. However, the floating floor sound insulation material is under the concrete cushion layer and must withstand multiple loads such as the cushion layer, the finishing layer, and the floor live load. For a long time, not only will the compression deformation be large and the floor will settle, but the sound insulation performance will also decay, and even the sound insulation performance will be lost after being flattened.

[0003] The "composite sound insulation floor and its construction method" disclosed in the Chinese patent application number 200710130940.2 is a sound insulation floating floor. Although the floating floor can meet the building sound insulation index, it has the disadvantages of complex construction process and long construction period, and the cost is high. It is limited in promotion and use. At present, only a few high-end buildings have floating floors.

[0004] Application No. 200910180036.1 provides a method for processing sound insulation pads for floor slabs, which reduces production costs and effectively solves the problem of poor sound insulation of hard tiles on concrete floor slabs, but the thermal insulation effect is still unsatisfactory.

They can be constructed once and are completed, with a short construction period, low cost, and easier to ensure construction quality. Nano-modified GPS flexible thermal insulation and sound insulation pads are made of nano-level dispersants, carbon nanotubes, natural graphite, and polystyrene to increase material strength, toughness, and damping effect. The product has moderate dynamic stiffness and high compression strength, low thermal conductivity, good sound insulation, good environmental protection, and strong fire resistance, which better solves the thermal insulation and sound insulation problems of household floors.

[0047] The processing steps of nano-modified GPS flexible thermal insulation and sound insulation pad are as follows:

[0048] Step 1: organically combine the raw materials to form a stable tubular network foam structure;

[0049] The specific steps of organically combining the raw materials to form a stable tubular network foam structure are:

[0050] A1. Place the nano-dispersant in a clean and dry stainless steel container;

[0051] A2. Dilute the nano-scale dispersant according to a volume ratio of about 1:2 (dispersant: solvent), and stir with an electric stirrer at a speed of 800-1000 rpm for 40-60 minutes to ensure that the dispersant is fully dissolved and evenly dispersed;

[0052] A3, immersing the carbon nanotubes in a mixed acid solution of concentrated sulfuric acid and concentrated nitric acid in a ratio of 3:1, ultrasonically treating in a constant temperature water bath at 70-80°C for 3 hours, then rinsing with deionized water until neutral, and drying in a vacuum oven at 80-100°C for 24 hours for use;

[0053] A4. Add the treated carbon nanotubes and natural graphite into a high-speed mixer, start the low-speed stirring mode, set the speed at 300-400 rpm, and stir for 8-10 minutes to preliminarily mix the carbon nanotubes and natural graphite to prevent agglomeration;

[0054] A5, add the diluted nano-scale dispersant in A2, increase the stirring speed to 900-1100 rpm, and continue stirring for 25-30 minutes to allow the dispersant to evenly coat the carbon nanotubes and natural graphite to form a stable mixed system;

[0055] A6, pour the polystyrene particles into the A5 mixing system, maintain the stirring speed at 900-1100 rpm, and stir for 20-25 minutes to allow the polystyrene and the mixture containing carbon nanotubes and natural graphite to fully blend;

[0057] A8. The extruded material is extruded through a customized die to form a sheet of the desired shape;

[0058] A9. Use a cooling roller to cool and shape the extruded sheet. The cooling water temperature is controlled at 20-25°C for 10 minutes to ensure that the sheet has stable size and regular shape, and obtain a finished product of a nano-modified GPS flexible thermal insulation pad.

[0059] Step 2, frequency and voltage modulation of the nano-modified GPS flexible thermal insulation and sound insulation pad;

[0060] The specific method of frequency and voltage modulation of nano-modified GPS flexible thermal insulation and sound insulation pad is:

[0061] The frequency modulation and pressure regulation method of the nano-modified GPS board is to compress and relax the nano-modified GPS board through single or multiple extrusion treatment, and adjust the dynamic stiffness from s'1 to s'2, and adjust the compression strength from σ1 to σ2, and perform single or multiple frequency modulation and pressure regulation, so that the dynamic stiffness is finally within a specific range of s'a to s'b below 30MN / m, and the compression strength is above 20kPa;

[0062] When the dynamic stiffness of the nano-modified GPS flexible thermal insulation and sound insulation pad is controlled within a specific range of less than 30MN / m, its resonance frequency can be basically guaranteed to be below 100Hz. At the same time, the compression strength of the nano-modified GPS flexible thermal insulation and sound insulation pad is controlled above 20kPa, so that it can withstand the deadweight of the floating plate of the floating floor system, the deadweight of the upper finishing layer and the use load of the floor, reduce the ground settlement, avoid cracking of floor tiles, reduce the risk of uneven settlement, and avoid affecting the comfort and safety perception of use. The nano-modified GPS board is modified in various ways, so that the product can withstand and very appropriately adapt to the repeated squeezing and release of large-tonnage compressors during frequency and voltage regulation.

[0063] Step 3, cutting the nano-modified GPS flexible thermal insulation and sound insulation pad;

[0065] Step 4: Compounding an enhanced protective film on the surface of the cut nano-modified GPS flexible thermal insulation and sound insulation pad;

[0066] A composite enhanced protective film is formed on the surface of the cut nano-modified GPS flexible thermal insulation and sound insulation pad, wherein the protective film is made of a polyimide film;

[0067] The specific steps for composite enhanced protective film on the surface of the cut nano-modified GPS flexible thermal insulation and sound insulation pad are as follows:

[0068] B1. Use a clean cloth or dust-free paper to wipe the surface of the cut nano-modified GPS flexible thermal insulation pad to remove dust and impurities;

[0069] B2. According to the size and shape of the nano-modified GPS flexible thermal insulation and sound insulation pad, cut out a protective film of appropriate size. The size of the protective film is 5CM larger than the surface size of the thermal insulation and sound insulation pad so as to cover the entire surface;

[0070] B3. Apply glue or adhesive evenly on one side of the protective film, and then stick it on the surface of the nano-modified GPS flexible thermal insulation pad;

[0071] B4. Use a roller or other tools to press the pasted protective film to make it fit tightly. At the same time, fix the edge of the protective film to prevent it from warping or falling off;

[0072] B5. Check the pasting effect of the protective film to ensure that the protective film is evenly covered, without bubbles or wrinkles, and that it completely covers the surface;

[0073] The nano-modified GPS board is used as the raw material, extruded multiple times, cut into a certain thickness, and then pasted with a protective film on the plane, so that it can not only have thermal insulation and sound insulation properties, but also be able to withstand on-site construction loads and upper permanent loads and live loads, and can also withstand the thermal effects of the floor heating system, which is beneficial to sound insulation and noise reduction and to enhance the energy-saving effect of the building;

[0074] Fine stone concrete has built-in steel mesh, and fine stone concrete can also be replaced with a self-leveling mortar protective layer.
