▎ 摘　　要

NOVELTY - Vibration damping block comprises a damping base material (1) set on the inner layer. The damping base material is embedded with titanium-aluminum alloy elastic net (2). The outer surface of the damping base material is covered with a woven carbon fiber buffer net (3). The inner part of the damping base material is provided with an irregular buffer cavity (4). The outer surface of the gap of the woven carbon fiber buffer net is provided with multiple T-shaped bumps (5). The vibration damping base material comprises recycling 30-45% butyl rubber, 5-15% organic rare earth modified polyphenylene pyridine and diimidazole short fiber, 5-10% organic rare earth modified short polyimide, 2-5% 4, 4'-bis (2, 2-dimethyl-benzyl) diphenylamine, 2-3% oxidized graphene, 2.5-10% nano bamboo carbon fiber, 1.5-8% expanded graphite nano powder, 22-4.5 % calcium oxide, ferrous oxide and titanium dioxide, 1-2.5% zinc stearate, 1-5% aluminum oxalate and 30-45% filler. USE - The block is useful for air conditioner product (claimed). ADVANTAGE - The block: has multifunctional high performance damping effect, strong working ability and long service life; improves the stability, anti-aging and rigidity; is coated with light titanium-aluminum alloy elastic net and organic woven carbon fiber buffer net on the surface of the conventional damping damper block; improves the damping-damping effect of the damper; avoids the damper to reduce the service life because of breaking; improves the performance and comfort and prolongs the service-life and value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a test technique of vibration damping block comprising (a) inspecting appearance and size: filling the prepared irregular buffer cavity with non-Newtonian fluid, filling the damping base material with multiple T-shaped bumps, visually inspecting on the outer surface for appearance quality, using the steel ruler or steel tape measure, measuring the thickness by vernier caliper and carrying out the next step if it is qualified, (b) weighing the vibration damping base material by an electronic scale with precision ≮ 0.1 g, (d) adhesion test: placing a clean test piece at 23±2℃(50mm×50mm×6mm chrome-plated steel block) in the middle of the (100mm×50mm×10mm) surface of the damping base material, pressing the test piece self-weight pressurizing for 10 seconds, slowly lifting the test piece, hanging the damping base material, damping base material is not dropped in 1 minute, if qualified, performing the next step, (e) copper pipe adhesion test: warping the vibration damping base material in the width direction of 9.5 mm of copper pipe (damping base material and the length of the copper pipe is less than or equal to 15 mm), the normal temperature 23±2℃ for 1 hour, vertically hanging at 130±3℃ for 3 hours, observing whether the damping base material has flicking, falling phenomenon, if it is qualified, performing the next step or mixing the damping base material into a certain amount of damping mass, placing into the pressure machine to press the sample with the thickness of 10 mm, (f) Tensile performance inspection: mixing the damping base material into a certain amount of damping mass, placing the pressure machine into sample with thickness of 10 mm thickness, cutting out the sample of 150mm×20mm×10mm, placing for 1 hour at normal temperature, placing in the tension machine for axial stretching, setting the stretching speed is 200 mm/minute to measure, performing the next step, calculating the tensile strength based on formula: in the formula: σ - tensile strength, kPa, F-maximum tension, N, sample section area, m2, (g) heat-resistant aging test: placing the damping base material on the release paper at 80±3℃ for 3 hours, taking out immediately at normal temperature (23±2℃) for 2 hours, measuring the peeling strength, the qualified the next step, measuring the peeling strength, if qualified, then performing the next step and (h) weather resistance test: placing the damping base material into the xenon arc lamp weatherproof tester, setting the black mark temperature of the xenon arc lamp weatherproof tester is 65±3℃, the relative humidity is 50±5%, where the pass band the wavelength the between the 290-800 nm, selecting 550 w/m2irradiance, each water spraying time is 18 ±0.5 minutes, the anhydrous time between the two times of water spraying is 102±0.5 minutes, observing the damping base material after 24 hours of xenon lamp irradiation after the damping base material is qualified, DESCRIPTION OF DRAWING(S) - The drawing shows a schematic cross-sectional view of a vibration damping block for air conditioning product. 1Damping base material 2Titanium-aluminum alloy elastic net 3Woven carbon fiber buffer net 4Irregular buffer cavity 5T-shaped bumps
