Description
Technical field
Invention relates to environment-friendly materials field, and specifically a kind of nano-calcium carbonate strengthens ecological wooden material and preparation method thereof.
Background technology
Ecological wooden is with agriculture and forestry organic waste material and waste or used plastics for main raw material, processes according to the feature of filling plastic modification and macromolecule interfacial compatibility principle.This material has raw material resources, product plasticization, and use environmental protection, economical, reclaiming is a kind of real environmental protection shaped material.It has the dual nature of plastics and timber: waterproof, fire-retardant, corrosion-resistant, Anti-moth-eating, and plasticity-is strong, easy to process, once shaped, not containing the toxic and harmful such as formaldehyde, benzene, is a kind of novel for Wood products.Be widely used in landscape architecture, communication and logistics, interior/exterior decoration finishing, office furniture etc.But because wood fibre surface exists polar hydroxyl groups, surface energy is high, and polyvinyl chloride resin surface is comparatively low-pole, with wood fibre poor compatibility, produces interfacial separation, reduces mechanical property, shorten work-ing life, define its use range.Nano material due to size little, specific surface area is large and produce quantum effect and surface effects, has many special excellent properties.And nano-calcium carbonate is one of inorganic nano material developed the earliest, because it is cheap, the characteristic such as wide material sources and nontoxic pollution-free, be widely used in many fields such as chemical industry, medicine.But because nano-calcium carbonate has great specific surface area and higher specific surface energy, very easily particle aggregation is there is in preparation and last handling process, layering, fly upward, in use lose quantum effect and surface effects, do not have the effect of activeness and quietness, because which limit its application in suitability for industrialized production.

3) by modification wood fibre, modified PVC resin, light calcium carbonate 50 ~ 60 parts, 0.2 ~ 1 part, colorant, 2 ~ 10 parts, elastomerics, lubricant 0.5 ~ 1 part and 0.5 ~ 5 part, softening agent, 80 ~ 100 DEG C of mix and blend 5 ~ 15min, cold mixed 5 ~ 10min obtains Preblend, and Preblend granulation is obtained particle I;
4) by particle I extrusion moulding, get product through mould, cooling, traction, cutting;
Described wood fibre filler is selected from more than one of wood powder, chaff powder or straw powder; Coupling agent is selected from the two or more of acrylate, titanic acid ester or Aluminate; Elastomerics be selected from chlorinatedpolyethylene, SBS or ACR more than one; Stablizer is selected from more than one of calcium-zinc composite stabilizing agent, organic tin stablizer, compound lead stabilizer or rare-earth stabilizer; Lubricant is selected from more than one of paraffin, clorafin, polyethylene wax, oxidized polyethlene wax, stearic acid or vinyl bis-stearamides; Softening agent is selected from more than one of epoxy soybean oil, dioctyl phthalate (DOP) or dibutyl phthalate.
Invent the advantage that has and positive technique effect is: in system, have employed double-contracting cover modification technology surface modification treatment is carried out to wood fibre filler, improve the consistency of wood fibre and matrix resin, extend the work-ing life of material, also solve nano-calcium carbonate easily to reunite simultaneously, processing layered, fly upward large, be difficult to the problem realizing industrial applications.Nano-calcium carbonate because size is little, the large generation quantum effect of specific surface area and surface effects, on the basis of gaining in strength, improve toughness.By polymer carrier, nano-calcium carbonate is evenly distributed in macromolecule surface, forms polymer segment, avoid nano-calcium carbonate in production process and easily reunite, process layered, fly upward large defect.And then improve the mechanical property of material, widen its range of application.Utilize quantum effect and the surface effects of nano-calcium carbonate, elastomerics and nano-calcium carbonate not only enhance the strength of materials but also create coordination plasticizing effect in system, compared with other ecological wooden materials, the mechanical property such as toughness and intensity is more excellent, and range of application is wider.In sum, the present invention has raw material resources, product plasticization, uses the advantages such as environmental protection, economical, reclaiming.
For step 1) 90 ~ 100 DEG C of mix and blend 5 ~ 10min, Main Function is the moisture in removing fiber, and the too high meeting of temperature causes power loss, the too low object do not reached except moisture of temperature.Stirring velocity 2000r/min, the too fast wearing and tearing that can strengthen machine of rotating speed, rotating speed is too low can reduce production efficiency, therefore adopts this speed range.Step 2) in 100 ~ 110 DEG C of mix and blend synchronization rapid 1), the too high meeting of temperature makes PVC decompose, and the too low effect that can not reach moistened surface, therefore adopts this temperature range.Step 3) in 80 ~ 100 DEG C of mix and blend synchronization rapid 1), in mixing process, heat is mainly from the frictional heat of storeroom, the setting of temperature mainly plays regulatory role, the too high meeting of temperature makes whipping agent decompose in advance, impact processing, the too low mixed effect of temperature is bad, therefore adopts this temperature range.
