Definitions
- the invention relates to the wood composite material defined in the preamble of claim 1 and to the method for making wood composite material defined in the preamble of claim 9.
- Wood-plastic composite materials are made mainly from sawdust and plastic which are usually fed into the extrusion as granulates .
- the wood-based starting material as well as the plastic must therefore be first extruded in separate processes into granulates.
- the method is called direct feed.
- Wood-plastic composites made by the extrusion method are manufactured by adding a wood-based constituent and different processing auxiliaries as fillers to the matrix plastic.
- the wood-based constituents used are typically sawdust but may also be wood chips or chemical pulp fibre .
- the share of the added wood- based constituent in the plastic composite is from 5 to 90%, varying greatly according to the application. For example, in a product intended for outdoor use, the share of the wood-based constituent is less than 50%.
- the plastic used is most typically polyolefin, such as PP, LDPE or HDPE, but it may alternatively be PVC, PS or some other thermoplastic polymer, or a mixture of different plastics.
- the plastic used may be virgin or recycled plastic.
- the wood-based constituent added to the matrix reinforces the profile
- the fibre length and shape of the added constituent must be taken into account.
- the sawdust used in wood- plastic composites is so shaped that it does not actually reinforce the product but instead functions merely as filler in the plastic matrix.
- the size of the sawdust typically used in wood-plastic composites is in the range of 40 to 60 mesh (from 250 to 425 ⁇ m) , such that when it is used, some of the original length of the wood fibre is lost already at the production site of the starting material, such as a sawmill.
- the starting materials of the wood-plastic composites made from sawdust are pre-processed by granulation before the actual processing.
- the traditional wood-plastic composites have relatively high water absorbency and swelling compared to pure plastics. This is caused by hydrophilicity of the wood fibres and the relatively large surface area of the sawdust particles. It is commonly known that in a composite intended for outdoor use, the share of the wood-based constituent may not exceed 45%, being pref- erably less than 40%. The price of the composite is determined by the share and price of the required matrix plastic, such that demanding moisture conditions at the application site raise the price of the product considerably.
- Known from prior art is also manufacture of wood composites from wood waste arranged in the form of pellets, and from recycled plastic.
- Known from publication US 4874095 is also manufacture of wood composite materials from paper and thermoplastic mate- rial, and from publications US 20020034629 and US 3718536 manufacture of wood composite material from wood- and plastic-based materials.
- the objective of the invention is to eliminate the drawbacks referred to above.
- One specific objective of the invention is to disclose a new type of wood composite material and a method for making it.
- Another objective of the invention is to disclose a new method for processing adhesive laminate waste and a utility product produced in conjunction with the process .
- the invention is based on a wood composite material.
- the wood composite material is formed of adhesive laminate waste comprising adhesive material, glue and release material and being arranged into chaff, the chaff being arranged into the wood composite material.
- the invention is based on a method for making wood composite material.
- the adhesive laminate waste arranged into chaff and comprising adhesive material, glue and release material is arranged into wood com- posite material, preferably without pre-granulation of the adhesive laminate material into pellets.
- the chaff is arranged into wood composite material by extruding, die casting, plate pressing or in a similar manner.
- the wood composite material refers to a combined product made from waste ma- • terial obtained from the adhesive laminate industry and its buyers and comprising adhesive material, e.g. labels, surface material or the like, and glue and re- lease material.
- the adhesive laminate waste is formed of adhesive material onto which has been arranged a glue line, and adapted onto the glue line, to function as a protective sheet for it, is the release material that can be easily released at the application site.
- the glue is selected from the group consisting of dispersion glue, hot melt glue or mixtures thereof. Glues known per se can be used in the adhesive laminate.
- the adhesive material and/or the release material comprises a wood-based component and/or plastic- or polymer-based or other organic component .
- the adhe- sive and/or the release material is a wood fibre -based paper, paperboard or the like.
- the adhesive and/or the release material is a fine paper, i.e. a wood-free paper, and does therefore not contain lignin.
- the wood fibre -based paper, paperboard or the like comprises or is treated with plastic- or a polymer-based material.
- the adhesive and/or the release material may be formed of substantially plastic- or polymer-based material .
- the release material comprises a silicone-based component. The release material is preferably siliconized.
- the adhesive laminate waste comprises additional plastic which may be virgin or recycled plastic.
- the wood composite material may be made without or with the additional plastic.
- additional plastic e.g. polyolefin, polypropene, polyethene (HDPE, LDPE) , PVC or other suitable plastic or a mixture thereof is added to the adhesive laminate waste in order to make the wood composite material.
- the adhesive laminate waste and the additional plastic are led as one flow into the production of the wood composite material.
- the adhesive laminate waste and the additional plastic are led as separate flows into the production of the wood composite material.
- the adhesive laminate waste and the additional plastic may preferably be mixed into a homogenous mixture before making the wood composite mate- rial.
- the additional plastic is led into the adhesive laminate waste in conjunction with the making of the wood composite material.
- the amount of the added plastic is preferably less than 50%, more preferably in the range of 10 to 30%.
- the adhesive laminate waste or some of its constituents comprise a sufficient amount of a plastic- or a polymer-based component without the addition of the additional plastic.
- the adhe- sive laminate waste comprises additives.
- the desired and suitable additive/s are added to the adhesive laminate chaff before arranging the chaff into wood composite material, e.g. before extrusion, and/or during making of the wood com- posite material, e.g. during extrusion.
- the additive used may be a coupling agent, e.g. MAPP (maleic anhydride derivative) , for improving the adhesion between the adhesive laminate chaff and the polymer/plastic, talc for smoothing the surface and creating rigidity, a colorant and/or a slip agent.
- MAPP maleic anhydride derivative
- talc for smoothing the surface and creating rigidity
- different fire retardants, anti-mildew agents, uv-stabilizers or such may be used as additives.
- the adhesive laminate waste comprises metal-based constituents.
- the mixture ratio between the adhesive laminate waste, the additional plastic and/or the additive is adjusted in the method.
- the properties of the wood composite may be tailored to be suitable for each product application.
- the composite provided from the adhesive laminate waste chaff is significantly more multifunctional as to its mechanical properties.
- the mechanical properties of the wood composite material such as elasticity, water absorbency, and other mechanical properties, are adjusted by changing the particle size of the chaff and/or the amount and quality of the additional plastic.
- the share of the adhesive laminate waste in the wood composite material is substantially more than 50%.
- the adhesive laminate waste is chopped and screened into chaff material of the desired particle size before making the wood composite material.
- the particle size of the chaff to be led into production is from 1 to 10mm. In one embodiment, the particle size of the chaff is from 3 to 5mm.
- the adhesive laminate waste may be chopped in conjunction with the method according to the invention, or it may already be in the chaff form.
- Finished adhesive laminate products and waste material produced from them or from their manufacture may be used for making the wood composite. Also production waste and recycling material from further processing and end use may be used.
- the adhe- sive laminate waste is obtained from adhesive laminate production, comprising mainly production waste, edge strip waste cut off from reels, and reel ends, from adhesive laminate press facilities, comprising mainly reel ends, adhesive material left over from die cutting stickers and labels, and waste, and/or from adhesive laminate end users who glue the pressed stickers and labels or the like onto the products .
- the waste obtained from the end users comprises mainly release material, reel ends and waste from the finished product.
- the kinds of adhesive laminate waste obtained from dif- ferent steps differ in their composition and can be mixed into a suitable adhesive laminate waste mixture. In this manner, by collecting waste from different steps of the life cycle of said product, and by recycling the collected waste, the principles of recycling and sustained development can be fulfilled.
- the sawdust and the wood-based constituents in the previously known wood-plastic composites comprise lignin which disintegrates due to uv-radiation, impairing the wood properties .
- the paper used in the adhesive laminate used in conjunction with the invention is in most cases made from chemical pulp and does therefore not comprise lignin. This makes the fibre fractions of the adhesive laminate more homogenous, stable and stronger, without the lignin.
- the chemical pulp fibre is also longer than the fibre material that has been ground mechanically.
- the method in accordance with the invention is suitable for use in the processing of different kinds of adhesive laminate waste materials and for making wood composites.

- the method in accordance with the invention is very simple, which reduces investment and processing costs.
- a profile intended to be used as a package edge board must be strong and sufficiently elastic to be able to stand the sharp compression force caused by tightening of the package binder.
- the adhesive laminate was chopped into chaff and the chaff was screened into particle sizes of 4 and 5mm. Both particle sizes had an equal share in the starting material flow.
- 10% of LDPE was added to the chaff, and the product was extruded into an L- profile at the production rate 158kg/h, the tempera- ture of the mass being 137 0 C.
- a test sample of 30 x 150 x 7.5mm was sawed off from the edge board profile and bent using 3-point flexion in accordance with standard SFS-EN ISO 178. The bending strength obtained for the material was 29.3N/mm 2 and the elasticity modulus was 1030N/ mm 2 .
- Laminate reel cores must be strong and rigid in order to stand the forces applied to the reel during use and to make the laminate reels dimensionally accurate.
- 15% of PP, 10% of talc and 3% of coupling agent was added to the adhesive laminate chaff of 3mm.
- the mass plastified with an extruder was run through a core mould at the rate 140kg/h, the temperature of the mass being 185 0 C.
- pieces of 100mm were sawed off from the core for testing their compressive strength in both horizontal and vertical directions at the rate lOmm/min.
- the compressive strength obtained for the material was 2.9 ⁇ 0. IkN in the horizontal and 78.8 ⁇ 1.2kN in the vertical direction.
- a patio board intended for outdoor use must be mechanically strong and also have low water absor- bency so that the moisture absorbing into the product would not cause any microbial growth, dimensional changes or other changes caused by moisture.
- 30% of LDPE was added to the adhesive laminate chaff of 4mm.
- the product was extruded into an L-profile at the production rate 80kg/h, the temperature of the mass being 170 0 C.
- Test samples were sawed off from the L-profile for testing their water absorbency in accordance with standard SFS-EN ISO 62. The obtained water absorbency was after 24 - 48 - 72 - 192 - 384 and 1152h 0.69 - 0.88 - 0.93 - 1.53 - 1.87 and 4.10%.
- samples were produced in accordance with example 3, but by adding 5% of coupling agent to the above-mentioned starting materials.
- the water absorbency obtained for the material was after 24 - 48 - 72 - 192 - 384 and 1152h 0.50 - 0.64 - 0.83 - 1.26 - 1.38 and 2.75%.
- the tests show that the material based on the adhesive laminate provided easily utiliz- able wood composite products, which could be easily equipped with the desired properties, e.g. strength, stability, elasticity, resilience and workability, for various applications .
