Abstract
The invention discloses a low-temperature type wood-plastic floor and a preparation technology thereof. The floor comprises substances of: plastic particles, plant fiber, a filling material, a compatibilizer, a lubricant, a pigment, and functional auxiliary agents. Compared with existing technologies, according to the invention, melted and modified plastic particles are adopted, the components are well formulated, and the mold of the product is improved. Under a temperature of -34 DEG C to 60 DEG C, the linear expansion coefficient of the prepared product is smaller than 5*10<-5>. When the product is processed through three times of freeze-thaw cycling tests according to ASTM D6109-10, the bending strength retention of the product is more than 97%.
Description
Technical field
The present invention relates to a kind of wood-plastic floor board and preparation technology thereof, the preparation technology on particularly a kind of low temperature resistant type wood-plastic floor board and this floor.
Technical background:
Wood-plastic floor board because of wood-plastic products moth-proof and mould-proof, weather-proof, non-maintaining, xyloid outward appearance, has become a kind of trend of new decoration as outdoor pavement material.In places such as garden landscapes, wood-plastic floor board adopts in a large number.But at present, at extremely frigid zones and round the clock or the big area of the four seasons temperature difference, the wood-plastic floor board of mating formation in early days exposes the product cracking, and cold and hot contraction is excessive, problems such as product jack-up warpage.Existing domestic also not to this type of problem, the low temperature resistant wood-plastic floor board product of developing special.Like national cold districts such as Northern Europe, Russia, Australia, the market outlook of outdoor flooring are wide, but existing flooring product is not made improvement exploitation targetedly to such weather condition.Therefore develop low temperature resistant type wood-plastic floor board, reduce cold and hot shrinkage coefficient, solve low temperature cracking down, the wood-plastic floor board of warpage becomes the direction that present wood is moulded industry research.
Summary of the invention:
First technical problem that the present invention will solve is that solution wood-plastic products linear expansivity is bigger than normal, and the warpage issues that cold and hot contraction causes is developed the wood-plastic floor board prescription that linear expansivity is low, freezing and thawing performance is good;
Second preparation technology that technical problem is said product that the present invention will solve.
The scheme of technical solution problem of the present invention is: a kind of low temperature resistant type wood-plastic floor board, contain following material and weight part:
Described plastic pellet is the reclaimed materials of Vilaterm, Vestolen PP 7052 virgin material or both mixtures or above plastics.
Described vegetable fibre is wood powder, bamboo powder and powdered rice hulls.
Described filler is lime carbonate, talcum powder, kaolin
Described compatilizer is Injecatable EVA Copolymer (EVA), chlorinatedpolyethylene, maleic anhydride inoculated polypropylene, maleic anhydride ring Vilaterm is a kind of or several mixture.
Described lubricant is polymeric amide, polyethylene wax, paraffin, stearates, above one or more composite
Described functional type auxiliary agent is oxidation inhibitor, UV light absorber or mould inhibitor.
The preparation technology of described wood-plastic floor board comprises following operation successively: high speed batch mixing, dehumidifying operation, granulation consolute operation, mould extrusion moulding operation, aftertreatment technology;
Described high speed batch mixing, dehumidifying operation are: take by weighing materials such as plastic pellet, wood powder by prescription, use rotating speed to mix as the high-speed mixer of 650-1300RPM, mixing time is 10-20 minute, and the dehumidifying temperature is 140 ℃, and the dehumidifying time is 10 minutes;
Described granulation consolute operation: use 75 type cocurrent and parallel dual-screw pelletizers, prilling temperature is controlled to be: 120-210 degree centigrade, electric current is the 140-150 ampere.
Described mould extruding-out process: use 65 or 90 type conical double-screw section bar forcing machines, temperature is 120-200 ℃, and die temperature is extruded current control at the 25-55 ampere at 120-180 ℃;
Described aftertreatment technology: with the processing of the sheet material of extruding through grinder and polishing machine, thereby the lubricant film of removing plate surface reaches xyloid surface effect.
In the mould extruding-out process; Mould is that solid, the mould of chamfering, above-mentioned mould have following characteristics: no sharp-pointed stress concentration dot structure, mould inside runner do not have the spreader structure to increase the inner density of product, lengthening cooling and shaping segment length, guarantees the sufficient typing of goods.
The present invention compared with prior art through selecting consolute modified plastics particle for use, reaches the collocation between each component, and to improving of product mold, the product that makes (34 ℃ to 60 ℃) coefficient of linear expansion is less than 5 * 10
-5Three circulating freezing resistance tests of ASTM D6109-10 are pressed in the circulating freezing resistance test, and the flexural strength conservation rate reaches more than 97%;
