Definitions
- the invention relates to a board, in particular to a board with an anti-skid function and a preparation method thereof; it belongs to the technical field of board manufacturing.
- Elastomers such as natural rubber, synthetic rubber, and thermoplastic elastomers all have a good touch, and are characterized by softness and elasticity. These characteristics make the board with the surface of the elastomer material have incomparable advantages in decoration compared with other materials, especially for indoor or outdoor flooring.
- the patent document whose authorized publication number is GB2445714B discloses a plate.
- the panels have an elastic surface and a rigid foam core as support beams.
- Its surface layer and core layer are both made of polyurethane, so the surface layer and core layer can be fused into one without the use of adhesives, and cannot be peeled off. It does not use any peelable technical means to connect the two.
- the polyurethane core layer is made of foaming process, the strength of the thermosetting polyurethane material as a support beam after foaming cannot fully meet the various strength requirements of the board in the application scene, so its polyurethane core layer is mixed with a certain amount of fiber To increase the strength of the overall core layer. Due to the surface elasticity of the board, the strength of the core layer is increased by fibers, and the two layers have good bonding force due to the use of the same material, so they have good touch and strength, and are widely welcomed by the market.
- the material cost of the polyurethane sheet is high, and the process of mixing fiber reinforcement in the manufacture of the core layer is very complicated, and involves the modification of equipment, making it difficult to popularize and apply the sheet on a large scale.
- the present invention aims to solve the above problems, so as to provide a board with anti-skid function.
- the board of the invention By replacing the core layer material, the board of the invention not only achieves a substantial reduction in material cost, but also enables it to meet the strength requirements of a fiber-reinforced polyurethane board without using fiber reinforcement.
- a plate with anti-slip function including a hard support body and an anti-slip body removably clamped on the support body;
- the anti-slip body has a planar body forming the use surface of the board, and the planar body extends toward the support body to form a clip;
- the supporting body has snap-in grooves that cooperate with the snap-in pieces and can be removed from each other; there is at least one in the snap-in slots that restricts the snap-in pieces from extending in the opposite direction to disengage from the snap-in The limit part of the groove;
- the support body includes a support body and a plurality of shaping parts arranged in the support body to prevent deformation of the support body;
- the support body is a cube structure with at least eight edge corners, the The shaping member simultaneously connects at least three of the eight edge corners;
- the body of the support body is made of thermoplastic material, and the anti-slip body is made of elastomer material.
- the material of the elastic surface layer is polyurethane
- the material of the hard core layer is rigid foamed polyurethane. Since both the surface layer and the core layer are polyurethane, there is no adhesive or any other peelable method. In this case, the surface layer and the core layer can be bonded by heat fusion.
- the prior art adopts the method of adding fibers to polyurethane, which solves the problem of insufficient strength of polyurethane itself, and achieves good technical effects.
- the material cost of polyurethane is high, and when polyurethane is extruded, fibers often block the mold, which results in high manufacturing cost of the fiber-reinforced core layer.
- the inventor hopes to solve the problem of high cost by replacing the material, and at the same time does not use fiber reinforcement to prevent the problem of mold blockage.
- fiber reinforcement to prevent the problem of mold blockage.
- the core layer and the anti-slip layer can be made of different materials, that is, the anti-slip body still uses polyurethane elastic material, while the core layer uses other cheap materials.
- This core material does not use fiber reinforcement, ie it must be strong enough. Obviously such materials are very numerous, such as various thermoplastic materials.
- thermoplastic materials can meet the strength requirements, due to their thermoplastic characteristics, in actual use, the shape and size of the support will change in harsh environments such as heat and water. Shrinkage, which will not only cause the mutual peeling of the support body and the anti-skid body, but also may cause the disintegration of the board in many cases.
- the material, shape, and installation position of the shape-setting component are all key to whether the size of the support can be truly locked. .
- the inventors found through a lot of experiments that since the support body is a three-dimensional structure and usually has eight corners, only three edge corners of the support body need to be locked to effectively reduce the shrinkage of the whole support body after being subjected to heat. Next, how to fabricate the structure at low cost and efficiently remains a difficult problem.
- the so-called connecting edge corner of the shaped part means that the closest distance between the edge of the shaped part and the corner apex of the support body is not greater than 25% of the width of the support body. Only in this way is it sufficient to prevent the thermoplastic material of the support body from shrinks in size. If it is not connected or the distance is too large, it will directly cause the size of the edge corner of the support body to shrink, resulting in the shrinkage of the overall plate size.
- thermosetting polyurethane is at a low level, and fibers are needed to increase its strength, while thermoplastic materials not only have high material strength, but also have cost advantages, so they are ideal. choose.
- Thermoplastic materials can be various polyolefins that meet strength requirements, such as polyethylene, polypropylene, and ethylene-propylene copolymers; they can also be homopolymers of olefins containing polar groups, such as polyvinyl chloride; they can also be modified Polyolefins, such as unsaturated carboxylic acid modification.
- the form of unsaturated carboxylic acid modification can be blending, copolymerization, grafting.
- Blending refers to mixing the polymer obtained by polymerization of unsaturated carboxylic acid with polyolefin, such as a mixture of polyacrylic acid and polyethylene; copolymerization refers to adding unsaturated carboxylic acid during the synthesis of polyolefin resin.
- Acid to obtain a copolymer of olefinic monomers and unsaturated carboxylic acid monomers, such as polymers with "-ethylene-acrylic acid-ethylene-" repeating units;
- grafting refers to the synthesis of polyolefin resins.
- the polymer chain undergoes a grafting reaction to add a side chain structure to the polymer chain, allowing the polymer to obtain additional groups, such as maleic anhydride grafted polyethylene.
- thermoplastics have higher Shore hardness and elastic modulus than thermoplastic elastomers, replacing rigid foamed polyurethane with thermoplastics can significantly increase the strength of the board without using fiber reinforcement. Based on the above description, strength includes two meanings, one is the ability to resist the collapse of the plate caused by heavy pressure, and the other is the ability to resist the elastic deformation of the plate caused by heavy pressure.

- the support body is rigid foamed polyurethane, it is thermosetting, so its size hardly changes even when it is heated.
- the present invention replaces the support body with a thermoplastic material. Thermoplastic materials, on the other hand, undergo dimensional changes when heated. It is foreseeable that after the floor is paved, especially when the outdoor floor is exposed to strong sunlight in summer, the floor will shrink irreversibly due to the increase in temperature. This makes cracks between adjacent floors, especially at the corners, which will produce cavities and expose the ground below the floors, seriously affecting the appearance, and even destroying the connection between the floor and the keel.
- the shaping component in the above-mentioned technical solution of the present invention is provided in order to solve the above-mentioned problems.
- the above-mentioned problems of the present invention are effectively solved.
- Experimental studies have shown that after the setting part is added, the heat shrinkage rate of the support body is reduced from more than 2.0% to about 0.005%; the linear expansion coefficient is reduced from 4.35*10-5 to 2.66*10-5; Effect.
- the support body is a cube structure with at least eight edge corners, and the shaping member connects at least three of the eight edge corners at the same time; this allows the shaping member to reinforce the support so that The support body does not shrink due to heat, because this shrinkage force is counteracted by the support force of the shaped part.

- the inventors have conducted experimental studies using such a scheme, but encountered the same problem in each experiment. The problem is that the side channels are always blocked, and the support body is not evenly foamed, so it is difficult to achieve the desired effect. After analyzing the above-mentioned problems, the inventor believes that there is a great pressure inside the main channel.
- the pressure in the main channel will be released in reverse along the flow channel of the setting part, and the pressure in the main channel will be naturally released.
