Description

A kind of Cortex Cryptomeriae Fortunei Radiciss three-layer wood composite flooring and preparation method thereof
Technical field
The invention belongs to wood floors production technical field, is related to solid wooden compound floor, more particularly to a kind of three layers of Cortex Cryptomeriae Fortunei Radiciss Solid wooden compound floor and preparation method thereof.
Background technology
With the drastically reduction of global wildwood resource, wood working industry occurs in that the phenomenon of raw material worsening shortages.And Timber floor is used as a kind of important ornament materials of interior decoration, and market demand is increasing.In order to solve timber supply and demand lance The quick-growing plantation based on poplar, Cortex Cryptomeriae Fortunei Radiciss is planted energetically by shield, China, has filled up the vacancy of timber resources.
In the domestic market, solid wooden compound floor is a class product with fastest developing speed in Flooring Industry, solid wooden compound floor Have again three-layer wood composite flooring and multi-layer solid wood composite floor point.At present, the compound central layer of three-layer real-wood is based on Masson Pine, But Masson Pine growth cycle is long, Costco Wholesale is high, and whole economic efficiency is not good.Therefore, it is multiple as three-layer real-wood using Cortex Cryptomeriae Fortunei Radiciss lath The sandwich layer on floor is closed, raw material can be shortened and become a useful person the cycle, reduce production cost, floor elasticity can be improved again, while ensureing ground The mechanical property of plate.And using Cortex Cryptomeriae Fortunei Radiciss thin plate as dash board, due to Cortex Cryptomeriae Fortunei Radiciss soft material, density is relatively low, so floor surface needs roller Apply wear resistant paint to increase surface abrasion resistance.
The content of the invention
It is an object of the present invention to disclose a kind of Cortex Cryptomeriae Fortunei Radiciss three-layer wood composite flooring.
Cortex Cryptomeriae Fortunei Radiciss three-layer wood composite flooring of the present invention, from top to bottom successively by wear-resistant primer layer 1, dash board 2, central layer 3 and base plate 4 constitute.
Wear-resistant primer layer 1 of the present invention, 5 ~ 200 μm of thickness.
Dash board of the present invention 2, is that Cortex Cryptomeriae Fortunei Radiciss are sawed into into the thin plate that thickness is 3.2~4mm.
Central layer of the present invention 3, is that Cortex Cryptomeriae Fortunei Radiciss saw is cutd open into into sheet material, then novelty saw is cut into width for 25~50mm, thickness For the Cortex Cryptomeriae Fortunei Radiciss lath of 8~9mm, Cortex Cryptomeriae Fortunei Radiciss panel side is spelled as central layer.
Base plate of the present invention 4, is that poplar is peeled into into veneer, and its thickness is 2mm.
Another object of the present invention, discloses the preparation method of this Cortex Cryptomeriae Fortunei Radiciss three-layer wood composite flooring, its technology Scheme be using Cortex Cryptomeriae Fortunei Radiciss thin plate as dash board 2, common Cortex Cryptomeriae Fortunei Radiciss lath as central layer 3, board using poplar board as base plate 4, by gluing, group Crude product surface obtained by the normal process steps such as base, hot-press gluing, cooling, sanding roller coat wear resistant paint again, finally prepared Cortex Cryptomeriae Fortunei Radiciss three Layer solid wooden compound floor.
Cortex Cryptomeriae Fortunei Radiciss are sawed into the thin plate that thickness is 3.2~4mm by dash board of the present invention 2, and moisture content is 10~12%.This Bright employing Cortex Cryptomeriae Fortunei Radiciss thin plate is used as dash board, it is intended to reduces cost, increases the economic benefit of enterprise.
Central layer of the present invention 3, by Cortex Cryptomeriae Fortunei Radiciss saw sheet material is cutd open into, then it is 25~50mm that novelty saw is cut into width, and thickness is 8 The Cortex Cryptomeriae Fortunei Radiciss lath of~9mm, its moisture content is 10~12%, and Cortex Cryptomeriae Fortunei Radiciss panel side is spelled as central layer, and the gap between Cortex Cryptomeriae Fortunei Radiciss lath is not More than 0.5mm.The present invention, as the sandwich layer of three-layer wood composite flooring, contributes to shortening raw material growth cycle using Cortex Cryptomeriae Fortunei Radiciss, Production cost is reduced, is increased economic efficiency, increase the elasticity on floor, while ensureing other mechanical properties on floor.
Base plate of the present invention 4, is poplar rotary cut venner, and thickness is 2mm, and moisture content is 8~10%.
The preparation method of Cortex Cryptomeriae Fortunei Radiciss three-layer wood composite flooring of the present invention, by Cortex Cryptomeriae Fortunei Radiciss thin plate, Cortex Cryptomeriae Fortunei Radiciss lath and poplar Veneer assembly and gluing, adhesive used is 180~220g/m for the glue-spread of Lauxite, dash board and base plate, is pressed during hot pressing Power is 0.85~1.0MPa, and hot pressing temperature is 95~100 DEG C, and hot pressing time is 6~12min, and health preserving 3 is needed after the completion of the hot pressing of floor Subdivision is carried out within~5 days to reduce deformation, then, the floor after subdivision first carries out sanding to base plate, then one time is carried out to dash board slightly Sand, twice washed ore, subsequently into painting technology, idiographic flow is:(UL86001-01)Aqueouss additive color →( UL8903 )Plus Hard-caked sediment paint 25g →(UK8908)Solidifying priming paint agent 20g → sanding(Sand paper mesh number 320#)→(UL8902SU )Wear-resistant primer 25g→ (UL8933)Sanding priming paint 20g → sanding(Sand paper mesh number 320#)→ (UM1112-0080)Finish paint → (UM1112-0080 )Finish paint.
Production technology of the present invention it is important that floor surface roller coat wear-resistant primer, is favorably improved floor surface wearability, Extend the service life on floor.
Wear resistant paint of the present invention is big for a surname(Shanghai)The UL8902SU super abrasive paint that coating company limited is produced, Coating weight is 25g/m.
In painting technology of the present invention, UL86001-01, UL8903, UK8908, UL8902SU, UL8933, UM1112-0080 is the model of paint, and manufacturer is big for a surname(Shanghai)Coating company limited.
