Abstract
The invention discloses a sheet material for flooring material comprising a synthetic resin layer and a decorative layer formed on the synthetic resin layer, wherein, the synthetic resin layer is divided into more than two separated areas. The invention also discloses a laminate for flooring material, which is formed by laminating the sheet material for flooring material on a wooden base material.
Description
The application be that March 31, application number in 2004 are 200410033233.8 the applying date, denomination of invention divides an application for the Chinese invention patent application of " laminate for floor board material ".
Technical field
The laminate for floor board material that the present invention relates to anti-caster, resistance to impact and have excellent water-resistance.
Background technology
In the past, as flooring material, what be widely known by the people was the flooring material that applying wooden decorative veneer also is coated with on veneer, perhaps that veneer and medium density fibreboard (MDF) is stacked, further the flooring material of applying wooden decorative veneer and coating on MDF.In addition, implement the fluting and the chamfer machining of the degree of depth that arrives veneer and MDF and slot part is set and chamfered section from wooden decorative plate side, thereby the flooring material that improves design of patterns also is widely known by the people.
But the wooden decorative veneer is cut thin obtaining with unstained natural timber, and from the exhausted problem of timber resources, the kinematic mounting of protection world resource, along with the timber price promotion, material has also reduced, and is difficult to obtain the picture timber of high-quality in the past always.
For this reason, as the substituent of wooden decorative veneer, can use the decoration sheet that beautiful patterns such as wood grain decorative pattern are printed.As its representative, can enumerate substituent, the substituent of applying decoration sheet on the aforementioned medium density fibreboard face of the duplexer of stacked veneer and medium density fibreboard (MDF) at applying decoration sheet on the veneer.But the former is the same when using the wooden decorative veneer, often sees caster-resistant and poor impact resistance, when slot part and chamfered section are set on the wooden decorative veneer, produces burr and hangnail etc., and their can scratch socks and stocking and jump silk.Have, the latter is the same when using the wooden decorative veneer again, often sees that because the MDF poor water resistance, the immersion of water has damaged dilation, the design of MDF.
In contrast, open in 2003-239517 number the spy, proposed veneer, synthetic resin layer and decorative layer stackedly, can make this synthetic resin layer as good laminate for floor board material such as specific physics value and caster-resistant, resistance to impact, water resistance.
But, if laminate for floor board material is subjected to the influence of the heat of the means of heating, will often see and produce following influence: veneer or synthetic resin layer produce thermal contraction or thermal expansion and laminate for floor board material are sent out stick up and when the decorative layer surface of laminate for floor board material implemented design, direction along the fiber on the top layer of veneer produces concaveconvex shape etc.In addition, also require further to improve the caking property of synthetic resin layer and decorative layer.
Thereby, wish to develop that size that variations in temperature causes changes less and as the laminate for floor board material of more cheap building materials.
