Description

A board used for floor and preparation method thereof
Technical field
The present invention belongs to the field of preparation of floor board, and specifically relates to a board used for floor and preparation method thereof.
Background art A wood-plastic composite board is a new high-tech environmental friendly decorative material produced by mixing evenly wood (wood cellulose, plant cellulose) acting as a base material, thermoplastic polymer material (plastic), processing aid and others, and then carrying out extrusion molding with heating through a die equipment. The wood-plastic composite board has properties of both wood and plastic, and is a novel composite material that can replace wood and plastic.
The raw materials for the wood-plastic composite board are wood materials comprising wood cellulose, plant cellulose and others, which are easy to absorb moisture and thus result in deformation and warping of the board, affecting the use thereof. On the other hand, the wood-plastic composite board uses a large quantity of adhesives in order to bond the wood materials together, and thereby introduces a large quantity of organic solvents such as formaldehyde, resulting in the content of the organic solvents such as formaldehyde in an indoor environment exceeding standard, which is harmful to human health.
Stone plastic floor in the prior art are often unable to meet the performance requirements for floor, and produces floor just simply by PVC foaming. Thus it has poor impact resistance, poor abrasion resistance, large residual indentation, and is unable to hold weights for a long time. 1
Therefore, there is a need to develop a board used for floor to replace the wood-plastic composite board. Said board is required to have characteristics of low moisture absorption and zero content of formaldehyde, and also overcomes problems of poor impact resistance, poor abrasion resistance and large residual indentation present in the stone plastic board in the art. Contents of the invention The purpose of the present invention lies in providing a board used for floor having low moisture absorption and no formaldehyde, and ideal properties of impact resistance, abrasion resistance and residual indentation. The board used for floor of the present invention is achieved by the following solutions: A board used for floor comprises a stone plastic plate and a semirigid PVC layer bonded on the stone plastic plate; The raw materials for preparing the stone plastic plate comprise the following components based on weight percentage:
PVC 45-60% light calcium carbonate 28-40% calcium zinc composite stabilizer 1-3% PVC internal lubricant 0.4-0.6% PVC external Lubricant 0.2-0.3% foaming agent 0.2-0.4% 2 sodium bicarbonate 0.3-0.5% PVC foam conditioning agent 3-5% toughening agent 1-3% PVC reinforcing agent 2-4%; with the sum of these weight percentages being 100%. Wood fibers contained in a wood plastic board are easy to absorb moisture, resulting in deformation of the board and making the board becomes warping or mouldy. On the other hand, adhesives for wood fibers in the wood plastic board contain a large quantity of formaldehyde, which results in a serious environmental pollution and is also harmful to human health. The floor board provided by the present invention contains no wood fiber, and thus a board used for floor having low moisture absorption and zero content of formaldehyde is obtained. In addition, bonding semirigid PVC on the stone plastic plate realizes the effects of impact resistance and abrasion resistance, and makes the product has elastic recovery ability and smaller residual indentation. The raw materials for preparing the stone plastic plate of the present invention comprise the following components based on weight percentage:
PVC 45-60% light calcium carbonate 28-40% calcium zinc composite stabilizer 1-3% PVC internal lubricant 0.4-0.6% PVC external Lubricant 0.2-0.3% 3 foaming agent 0.2-0.4%
Sodium bicarbonate 0.3-0.5% PVC foam conditioning agent 3-5% toughening agent 1-3% PVC reinforcing agent 2-4%; with the sum of these weight percentages being 100%. The raw materials for preparing the stone plastic plate of the present invention comprise no wood fiber. The stone plastic plate comprising no wood fiber is prepared by foaming and shaping the mixture of calcium carbonate and PVC under the action of the foaming agent. The stone plastic plate provided by the present invention has properties which can be comparable with those of the traditional wood plastic board, and are fully able to replace the wood plastic board to be used as a floor board. As a preferred embodiment, said PVC in the present invention is 8 type PVC. In the stone plastic plate used for floor board provided by the present invention, a board prepared by PVC foaming is a skeleton, and light calcium carbonate is used for filling. The filling uniformity and amount of the light calcium carbonate have great influence on the properties of the stone plastic plate. For example, if the distribution of the light calcium carbonate is not uniform, the stone plastic plate will have nonuniform hardness, poor impact resistance and poor elastic recovery ability; if the content of the light calcium carbonate is too low, the stone plastic plate will have insufficient hardness and reduced impact resistance; and if the content of the light calcium carbonate is too high, the hardness of the stone plastic plate is too high, and thus the elasticity is smaller, which makes a bad feel for a person when treading on the stone plastic plate. 4
With respect to the light calcium carbonate, the sedimentation volume has certain influence on the board used for floor. When the sedimentation volume is less than 2.2 mL/g, the distribution of the light calcium carbonate is not uniform in the stone plastic plate, which affects the uniformity of hardness of the stone plastic plate.
The sedimentation volume of the light calcium carbonate in the present invention is 2.4-2.8 mL/g, for example 2.5 mL/g, 2.6 mL/g, 2.7 mL/g, etc.; and the specific surface area thereof is 4-6 m2/g. PVC lubricants are classified into two types: external lubricant and internal lubricant. The role of the external lubricant is mainly to improve the friction between the polymer melt and the hot metal surface of the processing equipment. The role of the internal lubricant inside a polymer is to reduce intermolecular cohesion of the polymer, so as to improve the internal friction heat and melt fluidity of a plastic melt.
The PVC internal lubricant of the present invention is preferably G60 internal lubricant; and preferably, the PVC external lubricant is PE wax.
Preferably, the foaming agent of the present invention is AC foaming agent.
The PVC foam conditioning agent of the invention is PVC foam conditioning agent LP-90.
The addition of PVC foam conditioning agent can promote PVC plasticizing, improve the melt strength of PVC foaming material, prevent bubble from merging, make a uniformly foaming product to be obtained, and ensure good fluidity of a melt and a good appearance of the obtained product.
The toughening agent of the present invention is chlorinated polyethylene. The addition of the toughening agent can improve the toughness and impact resistance of the board. 5
The PVC reinforcing agent of the present invention is PVC reinforcing agent JM01. The addition of the reinforcing agent can increase the modulus of the material.
As a preferred embodiment, the raw materials for preparing the stone plastic plate of the present invention comprise the following components based on weight percentage: 8 type PVC 45-60% light calcium carbonate 28-40% calcium zinc composite stabilizer 1-3% G60 internal lubricant 0.4-0.6% PE wax 0.2-0.3% AC foaming agent 0.2-0.4% sodium bicarbonate 0.3-0.5% PVC foam conditioning agent LP-90 3-5% chlorinated polyethylene 1-3% PVC reinforcing agent JM01 2-4%; with the sum of these weight percentages being 100%.
As a preferred embodiment, the raw materials for preparing the stone plastic plate of the present invention comprise the following components based on weight percentage: 8 type PVC 52.5% light calcium carbonate 35% 6 calcium zinc composite stabilizer G60 internal lubricant 0.5% PE wax 0.2% AC foaming agent 0.3% sodium bicarbonate 0.4% PVC foam conditioning agent LP-90 4.2% chlorinated polyethylene 2.1% PVC reinforcing agent JM01 2.8%. 2%

Preferably, the raw materials for preparing the semirigid PVC layer comprise the following components based on weight percentage: PVC 100 ground calcium carbonate 400 DOTP 35 7 calcium zinc composite stabilizer 3.5.

The thickness of the PVC layer bonded on the stone plastic plate is 1 ~2 mm. The bonding of the semirigid PVC layer and the stone plastic plate is realized through an adhesive, which can be any one of the adhesives used for PVC available in the art.
