Description
Technical field
The invention belongs to rotational moulding field of material technology, relate to rotomoulded articles of a kind of resistance to swiping and preparation method thereof.
Background technology
The large-scale recreation facility of rotation molding had both been overcome over iron and steel cement form and child had been easily generated injury of colliding with, again
Overcome that brushing paint produces migrates the pollution that causes child because of harmful substance, is the body-building that the head of a family is relieved, child likes
Mode, meanwhile, develops children's intelligence, adds child's intercourse ability, has great benefit to child grows.But by
Plastic raw materials in rotation molding is typically linear low density of polyethylene, and the softer resistance to swiping of relative texture is poor, particularly exists
When grittiness, dust are attached to surface, deeper to the superficial injury of rotomoulded articles, affect color, surface of plastic products once by
Destroying, will change the coefficient of friction of damaged part, accelerated wear test makes it destroy, it is also possible to cause degradation, too early aging,
Embrittlement.Current most of rotational moulding producers use resin to add pigment rotation molding, and goods are not the most made more in terms of resistance to swiping
Work.
The existing technology of rotational moulding is that producer uses the resin dedicated direct rotation molding of rotational moulding, or the most direct
Being added to by toner in resin and produce, common rotational moulding toy formula is to add 5～10 parts in rotation molding polyethylene after grinding
Toner.
Research in terms of polyethylene wearproof, is more high density polyethylene (HDPE), ultra high density polyethylene aspect, this be by
Its key property determines.Itself density is higher, quality is harder, and wearability is of a relatively high.Nanometer is have studied such as Wang little Wei etc.
UHMWPW/Al2O3Composite friction and wear property at different temperatures, finds to add the Al of 5%2O3Material wear-resistant performance is relatively
Good.
Tsing-Hua University He Peng, Zhao Anchi etc. have studied nano-silicon dioxide modified high density polyethylene (HDPE) wearability (plastics,
Phase calendar year 2001 1 volume 30), find SiO2When addition is 2%, the performance of system is best, and the particularly dry friction performance of system is best
Can improve more than 3 times, but there is SiO2Addition is less is difficult to homodisperse shortcoming.
2011, AMP mountain was delivered employing PA6 in engineering plastics are applied and is made rotational moulding with small particle glass microballoon modification
The PA6 that polyethylene rotational molding PP Pipe Compound adds 15% can improve mechanics and the hot property of composite, add 15% at coupling agent
The glass microballoon of reason can improve mechanics and thermal property, and it is inconspicuous that mobility, density can be kept to reduce, it is possible to fall
Low cost, can be used for high-temperature resistant and high rigidity aspect.But glass microballoon is bright and clean, hardness is big, has relatively macrolesion to grinder.
Low Density Polyethylene, linear low density polyethylene (LLDPE), density is low, quality is soft, and wearability is relatively low.But line style is close
Degree polyethylene and Low Density Polyethylene have advantageous advantage in rotational moulding is processed so that people have to think better of it
Using method, to play its maximum utility.
Summary of the invention
It is an object of the present invention to provide the rotomoulded articles of a kind of resistance to swiping, rotational moulding present in effective solution prior art

Described inorganic anti-wear agent includes Pulvis Talci, glass microsphere, aluminium hydroxide, silicon dioxide, preferably talc powder and two
Silicon oxide, Pulvis Talci is 1:1-5:1 with silicon dioxide composition weight ratio.Join that can to improve it in polymer significantly hard
Degree, rigidity, surface treated can significantly improve the mechanical property of blend.Pulvis Talci composition is main in layer with silicon dioxide
Shape structure, by stratiform sliding can occur during External Force Acting, has suitable lubricity, can reduce machinery and mill after addition
The abrasion of tool, and the addition of lubricant can be reduced.Silicon dioxide has bigger solid space structure, bulk density less than
0.1 gram every cubic metre, specific surface area tens to hundreds of square metre every gram, absorbability is very strong, and surface is with more polarity
Group, is commonly used in high abrasion goods, as being only second to carbon black in rubber tyre.But the harm of silica dust is long-term suction
Enter and easily cause pneumosilicosis, it has to be taken care that strengthen protection during use.
Described enhancement component uses nylon component, preferably nylon 6.The raising of plastic hardness, can improve resistance to significantly
Mill property.Being seen by its molecular structure, strand relatively steel is hard and polar functionalities.The effect of the steely muscle of nylon-type in the present invention, logical
Crossing employing compatilizer can make nylon component be evenly distributed in polyethylene body performance potentiation.The friction of nylon itself
Coefficient is low, also can reduce the coefficient of friction of goods when nylon component is distributed in surface.Nylon molecules contains polar group, with electrodeless
Anti-wear agent has fabulous adhesive attraction, can add the modifying agent of high-load, and prepared composite in nylon matrix.
