Description

ABS/ wood powder sectional materials and production method thereof
Technical field
The present invention relates to a kind of ABS/ wood powder sectional materials and production method thereof, belong to the technical field that ABS adds wood powder sectional materials technical recipe and production method thereof.
Background technology
Along with housing construction becomes the economic new growth point of China gradually, along with the enforcement of the protection engineering of the enforcement of China's strategy to develop western regions and natural forest, China's timber imbalance between supply and demand will be more outstanding, about 6000 ten thousand steres of annual timber breach.The quindecennial China in future only annual consumption of woodwork industry account for 40% of total sheet material by section bar, sheet material, then annual consume wood-based plate, the section bar of upholstery be about 1200 surplus ten thousand stere, building trade is about the 1800-2500 ten thousand stere, add communications and transportation (aircraft, automobile, steamer inside gadget etc.), home appliances, the required output of industry such as packing, advertisement, the market requirement is more than 3500 ten thousand steres, so produce a kind of have environmental protection, pollution-free, nothing contraction, the section bar that burning-point is high comes replacing wood to seem promising important.
Summary of the invention
A kind of ABS/ wood powder sectional materials and production method thereof have been the object of the present invention is to provide.The present invention has environmental protection, pollution-free, nothing contraction, the characteristics that burning-point is high.
In order to achieve the above object, technical scheme of the present invention is:
A kind of ABS/ wood powder sectional materials, component by following weight per-cent is formulated: vinyl cyanide, divinyl, monomer copolymer (K175) 0.6～1%, Cellmic C 121 (AC135) 0.2～0.5%, chain alkyl trimethoxies (silane silane coupling agent) 0.6～1.1% such as styrol copolymer (ABS) 20～28%, methyl methacrylate, acrylate and vinylbenzene, wood powder: 70～78%.
Described compositions in weight percentage is formulated as: vinyl cyanide, divinyl, monomer copolymer 0.8%, Cellmic C 121 0.3%, chain alkyl Trimethoxy silanes 0.9% such as styrol copolymer 24%, methyl methacrylate, acrylate and vinylbenzene, wood powder: 74%.
Vinyl cyanide, divinyl, styrol copolymer (ABS): every kind of monomer all has different qualities: vinyl cyanide has high strength, thermostability and chemical stability; Divinyl has tenacity, shock resistance characteristic; Vinylbenzene has easy processing, best bright finish and high strength.On form, ABS is non-crystalline material.Three kinds of monomeric polymerizations have produced has the biphase terpolymer, and one is the external phase of styrene-acrylonitrile, and another is the polybutadiene rubber disperse phase.The characteristic of ABS depends primarily on the molecular structure in three kinds of monomeric ratios and the two-phase.This just can have very big handiness in product design, and has produced the ABS material of hundreds of different qualities of market thus.The material of these different qualities provides different characteristics, for example therefrom waits until high shock resistance, smooth finish from low to high and high temperature torsion characteristic etc.The ABS material has superpower workability, appearance characteristics, low creep properties and excellent size stability and very high resistance to impact shock.
Monomer copolymers (K175) such as methyl methacrylate, acrylate and vinylbenzene: for disperseing modification AC.Nontoxic, nothing is smelt, and non-combustible pale yellow powder is compared with conventional AC whipping agent, and particle is thinner, and dispersed preferably, mobile, prevented from caking are arranged, and degradation production is nontoxic, pollution-free.
Cellmic C 121 (AC135): be active modification AC, nontoxic, nothing is smelt, non-combustible pale yellow powder, compares with conventional AC whipping agent, and decomposition temperature is lower, and degradation production is nontoxic, pollution-free.
Chain alkyl trimethoxy (silane silane coupling agent) is long chain silane coupling agent HD-1, molecular formula: CnH 2n+1Si (OCH 3) 3N=7～12; Outward appearance is colourless to pale yellow transparent liquid, content 〉=90.0%, and density is 0.8870～0.8910 (p 20) g/cm 3Refractive index is 1.3000 ± 0.0050 (n 2D 5), boiling point is 117～121 ℃/1.7mmHg.This product is soluble in the general organic agent such as hydrocarbon, ether, ketone, and facile hydrolysis, condensation form polysiloxane.
The degreasing wood powder, is pulverized, is sieved≤200 purpose wood powders at drying, degreasing.
The production method of described ABS/ wood powder sectional materials is: earlier wood powder and chain alkyl Trimethoxy silane were run up in mixing machine 35～50 minutes by certainweight per-cent, when temperature is stirred to 110 ℃, put into vinyl cyanide again, divinyl, styrol copolymer; Monomer copolymers such as methyl methacrylate, acrylate and vinylbenzene; Cellmic C 121; Restir to 120 ℃, cold then mixing to about 40 ℃; Unlatching ∮ 65 just diameter is the two forcing machines of forging of 65mm, sets 150 ℃ in a district, 165 ℃ in two districts, 170 ℃ in three districts, 178 ℃ in four districts, merging core is: 170 ℃, engine speed: per minute 0.6～1 changes, and each component that mixes is transmitted simultaneously by screw rod, forms blank in extrusion die, head temperature: 150～170 ℃, and extrude extrusion temperature: 165～180 ℃, again through the stock mould plastotype, last inlet chest cooling, cooling temperature: 15～20 ℃.
The time of running up is 40 minutes in the described mixing machine, and head temperature is 160 ℃, and extrusion temperature is 170 ℃, and cooling temperature is 18 ℃.
Beneficial effect of the present invention is: ABS/ wood powder sectional materials of the present invention, have that environmental protection, hardness height, good toughness, supporting power are big, colour-fast, non-corrosibility strong, water-proof skid-proof, fire-retardant, advantage such as the secondary re-workability is strong, precision and glossiness height, and easy for installation, greatly reduce production cost.
