Description
Technical field
The invention belongs to field of compound material more particularly to a kind of modified rotational moulding composite material specials.
Background technology
Rotational moulding is a kind of molding process of hollow plastic product, also known as rotational molding.Relative to being molded and be blow molded into
The outstanding advantages of type technique, rotational moulding show equipment and mold small investment, are suitable for medium-and-large-sized and complex-shaped plastic products
Production, product almost internal stress free and is unlikely to deform.As a kind of emerging plastic molding method, rotational moulding in recent years just with
Surprising growth rate causes attracting attention for plastic processing industry.2007, China's rotational moulding LLDPE raw material total quantity consumeds were more than 5
Ten thousand tons, 2008, the market dosage of China LLDPE rotational moulding material was close to 100,000 tons.
In the U.S., rotation molding is based on working motion equipment and toy, and in addition there are container, automobile components etc.；In Europe
Continent, rotation molding are mainly used for industry and agriculture articles for use, automobile component, traffic articles for use etc..From the present situation of domestic rotational moulding industry and
Development is seen, since the country pulls domestic demand, rotomoulded articles to be stored in automobile accessories, coordinated with agricultural machinery, production and use of marsh gas utilization, chemical anticorrosion
And the fields such as transport, food and logistics packaging, fishery cultivating, children amusement facility and health and fitness facilities, military articles for use, minitype ship
There are numerous use client and potential customers, therefore, domestic rotomoulding market will sustainedly and stably increase, rotational moulding PP Pipe Compound
Growth space is very huge, and tool has been widely used and application prospect.
Since rotomoulded articles are chiefly used in open air, excellent anti-ultraviolet aging is needed.Currently, rotational moulding on domestic market
PP Pipe Compound is deficient, there are no the dedicated ageing-resistant material of rotational moulding, and rotational moulding producer, which is typically employed in polyvinyl resin, blends light
Stabilizer carries out rotational moulding production, ageing-resistant to achieve the purpose that, but the comprehensive performance of this blend composition and resin uniformity are poor.
Invention content
The present invention provides a kind of modified rotational moulding composite material specials, not only increase the ageing-resistant performance of composite material,
Also improve the comprehensive performance and uniformity of composite material.
In order to achieve the above object, the present invention uses following technical scheme：
A kind of modified rotational moulding composite material special is than other each substances according to quality using linear low density polyethylene as base-material：
High density polyethylene (HDPE) is 4%-5%, fatty acid amide 0.1%-0.15%, light stabilizer 0.2%-0.3%, and antioxidant is
0.1%-0.4%, calcium stearate 0.1%-0.2%, rubber plastic foam material 1%-2%.
In component described above, light stabilizer is benzophenone, benzotriazole, one kind in acrylic nitrile derivates or two
Kind or more the mixture that is compounded with arbitrary proportion, the antioxidant be selected as phenol, phosphite ester, triazine it is one or two kinds of with
On with arbitrary proportion compound mixture.
Advantageous effect of the present invention：The present invention provides a kind of modified rotational moulding composite material special, which not only has
There are preferable resin uniformity, thermal stability and rigid-tough balance, and there is resistance to UV aging outstanding and rotational moulding to add
Work improves the service life of rotational moulding composite material special.
