Detailed Description

The technical solution of the present invention is further explained by the specific embodiments with reference to the drawings.

Example one

The present embodiment provides a floor mat, as shown in fig. 1, which includes a floor mat body made of a foam material, wherein a plurality of sound insulation units 1 having the same area are formed on at least one surface of the floor mat body, each sound insulation unit 1 has at least one sound insulation structure 2, and the sound insulation structures 2 in adjacent sound insulation units 1 are different in at least one of number, shape and distribution position.

When sound penetrates through the surface of the sound insulation structure 2 which is irregularly distributed, air vibration in the sound insulation structure 2 is caused, and due to the friction resistance, the viscous resistance of air and the heat conduction effect, a part of sound energy is converted into heat energy, so that the sound absorption effect is achieved; meanwhile, because sound is normally transmitted in a straight direction, when the sound insulation structure 2 is irregularly distributed, part of unabsorbed sound can be irregularly reflected and transmitted in a different direction, and multiple disordered sounds are formed in a dispersing mode and offset mutually, so that most of sound is effectively isolated, and the sound insulation effect is good.

Traditional ground mat is owing to not being provided with sound-proof structure 2, and the surface of cylinder is smooth cambered surface to ensure that the upper and lower surface of fashioned ground mat body is the plane. And be provided with sound-proof structure 2 on the ground mat body that this embodiment provided, when manufacturing, only need on the cylinder surface set up with sound-proof structure 2 corresponding carving or sunk structure can. The engraving or debossing structures may be achieved by laser engraving. The foamed soft film layer is extruded by a pair of rollers to form the corresponding sound insulation structure 2. The ground mat body can be formed by one or more autorotations of the roller. Setting the circumference of the roller as C and the length in the axial direction as D, the width of the manufactured floor mat body is D and the length is nC (refer to fig. 1, wherein n is the number of rotation turns of the roller). The floor mat body formed by one rotation circle of the roller comprises a plurality of sound insulation units 1 with the same area, and at least one of the number, the shape and the distribution position of the sound insulation structures 2 in the adjacent sound insulation units 1 is different. The embodiment to the structural improvement of ground mat only need through change the cylinder structure of production ground mat can, production process is simple, does not increase production time and manufacturing cost almost, and realizability is strong, and is especially obvious to the weakening effect of impact sound. Compared with the prior art, the traditional ground mat is laid in consideration of shock absorption and foot feeling improvement, and even if the structure of the embossing is arranged on the ground mat, the regular embossing is designed in consideration of attractiveness, convenience in bonding with a floor and the like. In terms of sound insulation, the prior art also only considers the noise heard by a person using this layer of the floor, i.e. the airborne sound transmitted to the person when walking on the floor, and does not consider further attenuation of the sound penetrating the mat. Therefore, the floor mat provided by the utility model is a breakthrough improvement for the technicians in the field, the cost is hardly increased, the commercial value is high, the market is believed to be greatly popular, and the market acceptance is high.

It should be particularly noted that the sound-insulating units 1 referred to in the present embodiment do not actually divide the mat body into a plurality of portions having a solid body, but are logically divided virtual areas, and there may be no distinct boundary between adjacent sound-insulating units 1; the sound-insulating structure 2 is a solid structure. For the sake of understanding of the present embodiment, adjacent soundproof units 1 are indicated in the form of a dotted line in the drawings.

The sound insulation unit 1 is rectangular in shape and has an area of 1cm²~100 cm². In terms of sound insulation effect, if the area of the sound insulation unit 1 is too large, the number of the sound insulation structures 2 is small, the disturbance effect on sound is small, and the sound insulation effect is poor; if the sound insulation units 1 are too small, the difference between the adjacent sound insulation units 1 is not obvious on the whole, and the floor mat body becomes more uniform on the whole. From the feasibility of manufacturing, as the plurality of sound insulation units 1 are required to be formed when the roller rotates for one circle, when the area of the sound insulation units 1 is too small, the carved patterns or the sunken structures which are arranged on the roller and correspond to the sound insulation structures 2 are smaller and more, and the processing is difficult; when the area of the sound insulation unit 1 is too large, the carving or the depression corresponding to the sound insulation structure 2 is arranged on the rollerThe number of structures is small, the number of the finally manufactured soundproof units 1 is small, and the soundproof effect is weakened. Considered, the area of the soundproof unit 1 is 1cm²~100 cm²In time, a better sound insulation effect can be achieved. Specifically, the area of the soundproof unit 1 may be 1cm²、2 cm²、4cm²、9 cm²、10cm²、16cm²、20cm²、25 cm²、36cm²、40cm²、49 cm²、64cm²、70cm²、80cm²、81 cm²、100 cm²And the like.

The sound-insulating structure 2 may be a pressed hole, which is a blind hole or a through hole. When the pressure hole is the through-hole, arouse the air vibration in the through-hole, because the viscous resistance and the heat conduction effect of frictional resistance and air, will be considerable partly sonic energy and turn into heat energy to play the sound absorption effect, sound still contacts with the inner wall of through-hole simultaneously, and the inner wall of through-hole produces the disturbance effect to sound, makes sound unordered propagation, reduces certain energy. When the pressure hole is a blind hole, the inner wall and the bottom surface of the blind hole generate a disturbing effect on sound, most energy is consumed under the interference of air vibration in the blind hole, and the effects of sound absorption and sound insulation are achieved.

When the pressed hole is a blind hole, as shown in fig. 2, the bottom surface of the blind hole may be provided with a scattering mass 3 having a plurality of scattering surfaces protruding from the bottom surface of the blind hole. The number of the scattering blocks 3 in each blind hole is at least one. The sound is transmitted into the blind hole and is scattered for many times, and is eliminated in the blind hole, so that the sound is absorbed. The traditional material needs to be made thicker to achieve better sound insulation effect under the condition of the same thickness, so that the problems of cost increase, poor foot feeling and the like are caused. In the embodiment, after sound is transmitted into the blind hole, the scattering block 3 has a plurality of scattering surfaces, so that the sound is disturbed by the scattering surfaces when contacting the scattering surfaces, and meanwhile, the scattering block 3 has a plurality of scattering surfaces, so that the sound is disturbed for a plurality of times among the plurality of scattering surfaces, and the energy dissipation of the sound is large.

The scattering surfaces of the scattering blocks 3 form barriers 4 at their intersections, and the barrier 4 of all the barriers 4 of each scattering block 3, which is the farthest from the center layer of the mat, constitutes a support 5 for interacting with the ground. The blocking part 4 can provide more planes for disturbing sound, the sound can be transmitted back and forth between the scattering surfaces and the side surfaces of the blocking part 4 after being transmitted into the pressure hole, the number of sound contact surfaces is more, the disturbance effect is larger, and the sound dissipation amount is large; the floor mat can be extruded and deformed when being manually trodden when in use, and can be contacted with the ground when being trodden due to the arrangement of the blocking part 4, so that the interval in one pressure hole is divided into a plurality of intervals to form a sound-proof cavity bag, a sound loop is more complex, and the consumption effect on sound is larger; meanwhile, the blocking part 4 is contacted with the ground to form a supporting function, so that the foot feeling can be improved; and the support effect of the blocking part 4 is set, so that the hole pressing is not easy to cause larger deformation, and the opening area of the hole pressing can be set to be larger.

The distances from the supporting parts 5 of the two adjacent scattering blocks 3 to the center layer of the ground mat are equal, and the distance from the supporting parts 5 to the bottom surface of the blind hole is not more than the depth of the blind hole. Because the shape of blind hole, distribution position etc. are different, can cause the feel of foot of different positions different, and some local feels softer, and some local feels harder, and ground mat is ageing after long-term the use, causes the condition such as ground mat unevenness, skew easily. This embodiment utilizes supporting part 5 to support blind hole department, and 5 distances apart from the ground mat center layer of supporting part of two adjacent scattering blocks 3 equal for the feel of ground mat is more even, and the atress is more even, and life increases.

The foaming material is one or more of IXPE, EVA, XPE and foaming polyethylene. The material has the functions of sound absorption, noise reduction, shock absorption, buffering, heat insulation, moisture protection, corrosion resistance and the like. In the process of shaping ground mat body, the expanded material foams earlier and forms the soft rete that has certain thickness, and the even ground mat body of thickness is formed to the cylinder extrusion of a pair of interval distribution again. When the cylinder, the cylinder that distributes from top to bottom can extrude moulding to it, is provided with cooling structure in the cylinder simultaneously for to the cooling of ground mat body, make the ground mat body keep the shape after the extrusion.

This embodiment still provides a floor, and floor includes floor layer and the floor mat layer that plane dimension is the same, and the floor mat layer comprises above-mentioned arbitrary floor mat, and the floor mat layer bonds in the back on floor layer, and the thickness on floor layer is 1~18 times of floor mat layer thickness. Because the ground mat can give sound insulation effectively, lay this kind of floor with ground mat after, the effect of giving sound insulation between the upper and lower floor is better. The mat layer may comprise one, two or more layers of mat. The adjacent ground mats of the ground mat layer and the ground mat layer are bonded through glue layers.

The embodiment also provides a production method of the floor mat, which comprises the following steps:

preparing a pair of cylinders, wherein the peripheral surface of at least one cylinder is provided with a plurality of carving units with the same area, each carving unit is provided with at least one carving structure, and the carving structures in the adjacent carving units are different in at least one of number, shape and distribution position;

foaming the foaming material to form a soft film layer;

and (3) performing roller extrusion molding, namely enabling the soft film layer to pass through a pair of rollers, and extruding the soft film layer by the rollers to form the floor mat.

The floor mat is produced through the steps, and has the following advantages: firstly, in terms of manufacturing, the roller can be used for a long time, the roller is only required to be prepared at the beginning of production, the realizability and operability of the roller design engraving structure are higher, and the cost increase of the roller is little; secondly, the method hardly increases the production time, and has strong realizability and high economic value; in addition, the floor mat produced by the method has high added value, and due to the irregular sound insulation structure, when sound penetrates through the surface of the irregularly distributed sound insulation structure, air vibration in the sound insulation structure is caused, and due to friction resistance, viscous resistance of air and heat conduction, a part of sound energy is converted into heat energy, so that the sound absorption effect is achieved; meanwhile, as the sound is generally transmitted in the straight direction, when the sound insulation structure is irregularly distributed, part of unabsorbed sound can be irregularly reflected and transmitted in different directions, and multiple disordered sounds are formed in a dispersing mode and mutually offset, so that most of sound is effectively isolated, the sound insulation effect is good, and the use value is high; finally, the ground mat formed by the extrusion of the roller has higher quality.

It should be noted that the carving units referred to in this embodiment do not actually divide the outer circumferential surface of the cylinder into several portions having solid bodies, but are logically divided virtual areas, and there may be no distinct boundary between adjacent carving units, and the carving structure is a solid structure. In the method, the carving unit of the roller corresponds to the sound insulation unit of the ground mat, and the carving structure of the roller corresponds to the sound insulation structure of the ground mat.

The shape of the carving unit is rectangular with the area of 1cm²~100 cm². Because the peripheral face of cylinder need form a plurality of sculpture units, in order to guarantee the inhomogeneity of sound-insulating structure, sound-insulating unit should not undersize or too big, and the quantity of sound-insulating structure should be moderate. The area of the carving unit is considered to be 1cm²~100 cm²In time, a better effect can be achieved. In particular, the area of the engraving unit may be 1cm²、2 cm²、4cm²、9 cm²、10cm²、16cm²、20cm²、25 cm²、36cm²、40cm²、49 cm²、64cm²、70cm²、80cm²、81 cm²、100 cm²And the like.

The carving structure can be a cylinder protruding out of the peripheral surface of the roller. From this, the cylinder can extrude soft rete to make the anomalous pressure hole that has on the ground mat that forms, make the ground mat have effectual syllable-dividing effect.

The difference in shape of the engraving structures in adjacent engraving cells is represented by: at least one of the diameter of the column, the height of the column, and the cross-sectional shape of the column in the height direction is different. Thus, the formed mat can have irregular perforations.

The outer end surface of the column body is carved with an extrusion block which is protruded out of the end surface of the column body and is provided with a plurality of extrusion surfaces or a pit which is sunken into the end surface of the column body and is provided with a plurality of extrusion surfaces. Therefore, the scattering blocks with a plurality of scattering surfaces, which protrude or sink from the bottom surfaces of the press holes, can be formed in the press holes of the floor mat. Wherein the extrusion face corresponds with the scattering surface, and the scattering surface can make sound receive by the multiple disturbance of scattering surface when spreading into the pressure hole, reduces sound energy, improves the syllable-dividing effect of ground mat.

The engraved structures may also be depressions having multiple pressing surfaces that are recessed into the interior of the cylinder. Therefore, the surface of the ground mat forms a convex scattering block with a plurality of scattering surfaces.

The engraved structures are formed by laser engraving. The carving structure is formed on the surface of the roller in a laser carving mode, the processing process is simple and convenient, and the feasibility is high.

In the method, the foaming material is one or more of IXPE, EVA, XPE and foaming polyethylene. The material has the functions of sound absorption, noise reduction, shock absorption, buffering, heat insulation, moisture protection, corrosion resistance and the like. In the process of shaping ground mat body, the expanded material foams earlier and forms the soft rete that has certain thickness, and the even ground mat body of thickness is formed to the cylinder extrusion of a pair of interval distribution again. When the cylinder, the cylinder that distributes from top to bottom can extrude moulding to it, is provided with cooling structure in the cylinder simultaneously for to the cooling of ground mat body, make the ground mat body keep the shape after the extrusion.

Example two

As shown in fig. 3, the difference between the embodiment and the first embodiment is that the sound insulation structure 2 in the embodiment is not provided with a blind hole, but is provided with a plurality of scattering blocks 3 protruding directly to one side of the mat body, the scattering surfaces of each scattering block 3 form blocking parts 4 at intersecting positions, the blocking part 4 farthest from the central layer of the mat in all the blocking parts 4 of each scattering block 3 forms a supporting part 5 for acting with the ground, and the distances from the supporting part 5 of two adjacent scattering blocks 3 to the central layer of the mat are equal. When sound contacts the scattering surface and the blocking part 4, the sound is reflected by the irregular surface in an incongruous way, and a plurality of disordered sounds are formed in a dispersing way and are mutually counteracted, so that most of sound is effectively blocked. Utilize supporting part 5 to support, and the distance of the 5 supporting parts apart from the ground mat centre layers of two adjacent scattering blocks 3 equals for the feel of the ground mat is more even, and the atress is more even, and life increases.

The support 5 is a linear structure parallel to the middle layer of the mat. When the ground mat pressurized, supporting part 5 supports in subaerial, because supporting part 5 is linear structure, form the back with ground and contact, can separate the interval of supporting part 5 both sides for afferent sound is separated, weakens the energy of sound, and the sound of both sides is inhaled respectively, contact with diffuser surface, scattering block 3 in respective interval, receive the perturbation effect of diffuser surface and scattering block 3 after, the energy of sound weakens gradually, finally absorb a large amount of sound, reach syllable-dividing effect. The threadlike structures may intersect. Therefore, the crossed linear structures form a net-shaped structure, when sound is transmitted, the net-shaped structure can separate the sound in each grid, the sound in each grid is absorbed, and a good sound insulation effect can be achieved.
