Embodiment 1

[0045] This embodiment provides a floor mat, such as figure 1 As shown, the floor mat includes a floor mat body made of foam material, and at least one surface of the floor mat body is formed with several sound-insulating units 1 with the same area. The sound-insulating unit 1 has at least one sound-insulating structure 2. The sound insulation structures 2 inside are different in at least one of quantity, shape and distribution position.

[0046] When the sound passes through the surface of the sound insulation structure 2 which is irregularly distributed, the air in the sound insulation structure 2 is caused to vibrate. Due to the frictional resistance, the viscous resistance of the air and the heat conduction, a considerable part of the sound energy is converted into heat energy, thus playing a role. Sound absorption; at the same time, since the sound is usually transmitted in a straight direction, when the sound insulation structure 2 is irregularly distributed, part of the...

Embodiment 2

[0070] like image 3 As shown, the difference between this embodiment and Embodiment 1 is that the sound insulation structure 2 in this embodiment is not provided with blind holes, but a scattering block 3 with multiple scattering surfaces protruding directly to the side of the floor mat body , several scattering surfaces of each scattering block 3 form a blocking part 4 at the intersection, and among all the blocking parts 4 of each scattering block 3, the blocking part 4 farthest from the center layer of the floor mat forms a support for interacting with the ground Part 5, the distance between the supporting parts 5 of two adjacent scattering blocks 3 and the center layer of the floor mat is equal. When the sound touches the scattering surface and the blocking part 4, it is anisotropically reflected by the irregular surface, dispersed to form a plurality of chaotic sounds which cancel each other out, effectively isolating most of the sounds. The support part 5 is used for s...

Embodiment 3

[0073] This embodiment is an explanation for the sound insulation structures 2 in adjacent sound insulation units 1 described in the first embodiment having at least one difference in number, shape and distribution position. In the floor mat provided in this embodiment, the number and shape of the sound insulation structures 2 in adjacent sound insulation units 1 are the same, but the distribution positions are different. The following is an example of the structure of the floor mat of this embodiment.

[0074] Example 1: If Figure 4 As shown, the number of sound insulation structures 2 in adjacent sound insulation units 1 is one and all are blind holes, and the distribution positions of the blind holes in adjacent sound insulation units 1 are different in the corresponding sound insulation units 1 . Figure 4 Among the four sound insulation units 1 distributed in the middle array, the blind hole in the first sound insulation unit 1 is located at the center of the sound insu...

Abstract

The invention belongs to the technical field of sound insulation floors, and discloses a ground mat production method. The ground mat production method comprises the following steps of: performing roller preparation: providing a pair of rollers, the outer peripheral surface of at least one roller is provided with a plurality of engraving units with the same area, each engraving unit is provided with at least one engraving structure, and at least one of the number, the shape and the distribution position of the engraving structures in the adjacent engraving units is different; foaming a foamingmaterial, wherein the foaming material foams to form a soft film layer; and performing roller extrusion forming, specifically, making the soft film layer pass through the space between the pair of rollers, and making the rollers extrude the soft film layer to form the ground mat. The method is high in realizability and operability, the cost of the roller is slightly increased, the production timeis hardly increased, the realizability is high, and the economic value is high; besides, the floor mat produced in the mode is high in additional value, can effectively isolate most of sound, and isgood in sound insulation effect and high in use value.

Description

[0001] This application is a divisional application of "application number: 201910950034.X; patent name: a floor mat and floor" filed on October 9, 2019. technical field [0002] The invention relates to the technical field of sound-insulating floors, in particular to a production method of floor mats. Background technique [0003] Noise in buildings can be divided into airborne sound and impact sound according to the way it is generated and the characteristics of propagation. Airborne sound is caused by the vibration of the sound source, which causes the vibration of the surrounding air particles, and spreads out in the form of longitudinal waves with alternating density and density. For example, the sound that people hear when they walk is air sound. Impact sound is the noise generated when the vibrating body of the sound source is in direct contact with the building structure, or the impact between solids, and the vibration energy is directly transmitted to the building ...
