Abstract
The invention discloses a preparation method of high liquidity rotational moulding raw material powder. The method is that the rotational moulding raw material powder which is grinded by a grinder and has edges on the surface is placed in a particle composite system (PCS) to prepare spherical high liquidity rotational moulding raw material powder, wherein the rotational moulding raw material powder is the rotational moulding raw material resin powder which is prepared by grinding (and mixing evenly) one or more of raw materials, namely polyethylene, polypropylene, acrylonitrile-butadiene-styrene copolymer and polyethylene terephthalate; the dosage of the rotational moulding raw material powder each time is 5-50kg, the rotate speed of the PCS ranges from 500rpm to 6000rpm, and the running time is 1-10min. By adopting the method of the invention, the liquidity of the rotational moulding raw material powder is improved, the bulk density is increased, the quality of the rotational moulding product is increased and the cost is reduced; the rotational moulding raw material powder prepared by the method of the invention can satisfy the requirements on rotational moulding and the use of the product; and the method is convenient to operate and has good application effect.
Description
Technical field
The present invention relates to a kind of preparation method of high-fluidity rotational molding material powder, be applicable to that the rotational moulding material powder of the surface band corner angle of pulverizing through pulverizer is processed into subsphaeroidal or axiolitic rotational moulding material powder.
Background technology
The flowability of rotational moulding material powder and bulk density are two important factors that influence the rotomoulded articles performance.Generally speaking, the flowability of rotational moulding material powder is good more, and its bulk density is high more, behind rotation molding, easily makes the uniform rotomoulded articles of wall thickness, and is not easy to form the inadequate plastics of fusion in goods.But owing to generally be used for the pelletized resin high resilience and the toughness of production rotational moulding material powder, the particle of rotational moulding material powder is multi-angular shape mostly after existing disintegrating apparatus pulverizing.And the multi-angular feature of particle increases the frictional resistance of particle relative motion, and the tip of corner angle is easy to generate the static enrichment, reunites between the particle thereby easily, and powder fluidity is relatively poor, and bulk density is less than normal.Dimensional stability and the filling capacity in complex-shaped mould that this has influenced rotomoulded articles on the one hand cause product stress to concentrate on the other hand easily, influence its mechanical property and integral product quality, and above problem becomes the technical bottleneck of rotational moulding industry.In addition, because the adding of filler, as increasing of the purer resin rotational moulding of the melt temperature raw material of filling the rotational moulding material powder, molten limit broadens, and rotational molding technique is required to improve, and the quality of rotomoulded articles is also had a significant impact.Therefore, use pure production of resins rotational moulding material powder in the rotational moulding industry usually, this just makes that the cost of existing rotomoulded articles is higher.To sum up, if can eliminate the multi-angular feature of rotational moulding material powder particle surface, make its more subglobular.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of high-fluidity rotational molding material powder, can effectively solve the problem that the rotational moulding industry can't prepare the high-fluidity rotational molding material powder, the invention provides a kind ofly under the mechanical force condition, prepare the method for high-fluidity rotational molding material powder.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of preparation method of high-fluidity rotational molding material powder is characterized in that: will put among the particle hybrid system PCS through the rotational moulding material powder of the surface band corner angle that pulverizer is pulverized, and be prepared into the rotational moulding material powder of torulose high fluidity.
Preferably, the rotational moulding material powder is the mixed uniformly after crushed rotational moulding material resin of the raw material powder of polyethylene (PE), polypropylene (PP), acrylonitrile butadient styrene (ABS), ethylene glycol terephthalate (PET) or combinations thereof.
Preferably, the dosage of rotational moulding material powder is 5～50kg at every turn.
Preferably, the range of speeds of particle hybrid system PCS is 500～6000rpm.
Preferably, scope running time of particle hybrid system PCS is 1～10min.
The present invention is owing to adopted technique scheme, the flowability of rotational moulding material powder is improved, bulk density increases, improve the rotomoulded articles quality and reduce cost, the rotational moulding material powder that makes with the present invention can satisfy the requirement that rotation molding and goods use, and easy to operate, result of use is good.In view of developing rapidly of present chemical industry, environmental protection industry (epi), demand to rotomoulded articles increases severely, under the situation that no high-fluidity rotational molding material powder can be used, adopt particle hybrid system PCS, utilize the high velocity air that high-speed motion produced of PCS rotor to drive the plastics powder and do high-speed motion, this motion makes stages of labor friction between the particle, shear force in the powder; Particle and epitrochanterian blade produce friction, shearing, impact forces; And the friction of particle and outer casing inner wall, shear force; Under various frictions, shearing, impact force action power condition, be prepared into torulose high-fluidity rotational molding material powder, its popularization, application have great society and economic benefit.
