Description
Technical Field
The invention relates to the technical field of composite floors, in particular to a plate substrate.
Background
Existing composite flooring is typically made primarily from polyvinyl chloride (PVC) as the starting material. Specifically, the composite floor is formed by adding a color film layer and a wear-resistant layer on one side of a substrate made of polyvinyl chloride. The main materials of the board substrate produced by this extrusion process include polyvinyl chloride and calcium carbonate. The main reason for adding calcium carbonate into the substrate is that 1, the size stability of the plastic product is improved, and the calcium carbonate plays a skeleton role in the plastic product due to the addition of the calcium carbonate and has a great effect on the size stability of the plastic product. 2. The hardness and rigidity of the plastic product are improved, namely in plastics, particularly soft polyvinyl chloride, the hardness is gradually increased along with the addition of calcium carbonate, and the elongation is reduced along with the increase of the hardness. Fine particles, large oil absorption value and high hardness increment rate. On the contrary, the calcium carbonate with coarse particles and small oil absorption value has small hardness growth rate of the plastic. In soft polyvinyl chloride, the hardness increase rate of heavy calcium carbonate is the smallest, and precipitated calcium carbonate (light) is the second. 3. The processing property of the plastic is improved, namely the rheological property of the plastic can be changed by adding calcium carbonate. The calcium carbonate powder is added in a large amount, so that the calcium carbonate powder is beneficial to mixing with other components and processing and shaping of plastics. Due to the addition of the calcium carbonate, particularly after the calcium carbonate is subjected to surface treatment, the hardness of the product can be improved, and the surface gloss and the surface smoothness of the product can also be improved. In addition, due to the addition of calcium carbonate, the shrinkage rate, the linear expansion coefficient and the creep property of the plastic product can be reduced, and conditions are created for processing and forming. 4. The heat resistance of plastic products is improved, that is, the heat resistance is improved by adding calcium carbonate to general plastic products, for example, about 40% of calcium carbonate is added to polypropylene to improve the heat resistance by about 200 ℃. When the filling ratio of the calcium carbonate is less than or equal to 20 percent, the heat-resistant temperature is increased by 8-130 ℃. 5. The cost of the plastic product is reduced, namely the prices of the common light calcium carbonate and the heavy calcium carbonate are far lower than the price of the plastic, and the cost of the plastic product is reduced by adding the calcium carbonate.
Table 1 below shows the characteristic analysis of the current board substrate in different ratios of pvc and calcium carbonate.
TABLE 1PVCvsCaCO3
Ratio of | Density (g/cm3) | MOR | MOE |
2.2:1 | 2000 | 18 | 3000 |
3:1 | 2100 | 18 | 7000 |
3.3:1 | 2200 | 14 | 9000 |
As is clear from table 1, the greater the amount of pvc added, the greater the elastic modulus of the substrate, i.e., the greater the expansion and contraction rate of the substrate. However, by changing the angle, it appears that the flex modulus does not change as the pvc increases. From this, it is inferred that the flexural modulus of the plate substrate changes basically with the increase and decrease of calcium carbonate.
The board substrate can achieve the predetermined effect after being manufactured. However, because the global environmental protection requirements are becoming more and more strict and more important, people are gradually developing various products in a direction of being durable and degradable without losing the original designed efficacy. However, the above-described material combinations for the conventional plate substrates cannot achieve the purpose of degradation and weight reduction at all.

Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
The invention provides a board substrate which is mainly made of at least one thermoplastic material, at least one calcium carbonate and at least one natural material. The thermoplastic material is plastic which has plasticity at a certain temperature, is solidified after cooling and can repeat the process, and the molecular structure of the thermoplastic material is characterized by linear macromolecular compounds, generally has no active groups and does not generate linear intermolecular crosslinking when being heated. In this embodiment, the thermoplastic material is polyethylene. The calcium carbonate itselfCalcium carbonate is classified into heavy calcium carbonate, light calcium carbonate, colloidal calcium carbonate and crystalline calcium carbonate according to the production method, which is prior art. In the present invention, the calcium carbonate may be one or more of the above-mentioned classes. In order to reduce the overall weight of the plate substrate and enhance the Modulus of flexure (MOR), a naturally degradable material is selected from the material of the plate substrate, and the material can be one or more of numbness, sugarcane fiber and cork, wherein the numbness is at least 5-10 mm long, so that the elasticity and toughness of the plate can be increased after the numbness is added. After the natural materials are added, experiments prove that the elastic modulus of the plate substrate is about 6000, and the flexural Modulus (MOR) of the plate substrate is not less than 20, namely between 20 and 24, and is preferably 22. In addition, in addition to the single natural material described above, a mixture of one or more materials including numbness, cork, and sugar cane fiber may be added to the board substrate. Through experiments, when the natural material is numb, the natural material only enables the density of the board substrate to be 1700g/cm 3 Thus, the weight of the plate substrate can be greatly reduced. Also, in another embodiment, it can be seen that the numbing surface added may be preceded by maleic anhydride. Also, numbing fibers may be treated with alkali, preferably sodium hydroxide. Therefore, the surface energy can be increased for the subsequent processing and jointing of the plate in the future.
After the addition of the above natural materials, the physical characteristics of each item were compared with those of the original materials, and the data are shown in Table 2.
TABLE 2 PVC vs CaCO 3
Compared with the prior art, the natural material is added into the plate substrate, so that the durability of the plate substrate can achieve the expected purpose on the basis of not losing the basic flexural modulus of the plate substrate, and meanwhile, the plate substrate can achieve the degradable purpose.
As can be seen from the above description, the board substrate provided by the present invention, after being added with natural materials, has a flexural Modulus (MOR) that is not comparable to that of the existing product, and also has an elastic Modulus (MOE) that is not inferior to that of the existing product; therefore, the natural material is added, the characteristics of the natural material are not lost, and the natural material is more outstanding than the existing product in some aspects; furthermore, due to the addition of natural materials, the overall density is only 1700g/cm3 after the production is finished, which is far lower than that of the existing products. Weight reduction means that more finished products can be worn in transit with conventional shipping wear, thereby reducing the cost of more transportation.
The above description is only a preferred embodiment of the present invention and should not be taken as limiting the scope of the present invention, and any modifications, equivalents or 145-improvements within the spirit of the present invention are intended to be covered by the claims of the present invention.
