Description

HDPC thick china

Technical field

The present invention relates to a kind of plate, especially a kind of HDPC thick china.

Background technique

By taking WPC composite board as an example, structure is broadly divided into four layers: wearing layer, color film layer, layer of PVC and WPC substrate.Add Work method is roughly divided into four steps: the first step is calendering production layer of PVC；Second step is to press wearing layer, color film layer and layer of PVC At an entirety；Third step is the wood plastics composite substrate for being extruded to shape and needing thickness, i.e. WPC substrate；4th step is will to post Layer of PVC and WPC substrate overlayed with glue.

1, use wood powder as filler material in WPC substrate, because containing a large amount of hydrophilic radical-hydroxyl, plant fiber tool There is very strong polarity, and common resin matrix is not usually nonpolar, hydrophilic, therefore the phase between plant fiber and resin matrix Capacitive is very poor, and interface binding intensity is low, affects the mechanical performance of WPC substrate, therefore WPC plate is fragile, is unable to undergo to fall It falls and collides, transportational process higher cost；

2, plant stuffing degradable discoloration when processing and forming, is also easy to produce substrate color difference；

3, it is overlayed in process using glue, causes inevitably to contain formaldehyde in finished product WPC composite board Equal poisonous and harmful substances, cause Health Impact, environmental pollution.

4, glue, which overlays, may make layer of PVC and the peel strength of WPC substrate inadequate, be easy to produce and come unglued.

The product fabricated using the above production technology certainly will exist simultaneously following deficiency:

1, the processes such as the handling material due to caused by segmented lamination, turnover material, certainly will be in cost of labor, Yi Jiren Work labor intensity etc. needs pay bigger consumption；Loss and waste caused by its material transfer process are also extremely huge；

2, segmented laminate product generally requires to undergo the process of multiple heating, cooling, and energy consumption is huge, and properties of product are stablized Property is poor；

3, glue application technique is needed in processing technology, increases processing step, but also realize that continuous production difficulty is big, it is raw It is long to produce the period.

By taking traditional PVC plastic plate as an example, structure is broadly divided into three layers: wearing layer, color film layer, layer of PVC.Processing side Method is roughly divided into two steps: the first step is the layer of PVC of calendering production different densities；Second step is by wearing layer, color film layer and PVC The layer of PVC of layer or a variety of different densities is pressed into an entirety.

The product of single layer PVC base, partially soft in terms of quality, the Shortcomings in terms of mechanical strength.

The product of multilayer PVC base, since shrinking percentage is inconsistent, warpage, metaboly are serious, and product stability is poor.

Meanwhile there is the deficiency similar with WPC composite board in above-mentioned production technology.

In addition, waterproof performance is extremely important as decorative boards.Current lamination type plate and natural wood plate is equal Performance with moisture absorption either uses in a humid environment being used for a long time, and can absorb the moisture in air, generates drum Bubble will lead to deformation when serious, therefore people seal hole by addition melamine adhesive and waterproof material, but Effect can not accomplish that 100% is effective, and often release formaldehyde in these materials added, lead to air pollution.

American documentation literature US2014109507A1 discloses a kind of compound water-proof, and it discloses stick in wood-plastic board Lamella has good vision and tactile sense organ to obtain, while having outstanding waterproof performance.But the composite water-proof Plate it is fragile, be unable to undergo to fall and collide.
