Abstract
The invention relates to an easily-cleaned material, which comprises the following components in percentage by weight: 68% to 71% of polypropylene, 10% to 15% of UHMWPE (Ultrahigh Molecular Weight Polyethylene), 6% to 7% of titanium dioxide, 8% to 10% of filling materials, 1% to 2% of lubricants and 0.1% to 0.5% of pigment. According to the technical scheme, the strength and the aging-resistant performance of the casing of a plastic household appliance are enhanced; and the surface smoothness of the casing is improved, so that the casing is cleaned easily.
Description
Technical field
The invention belongs to polymeric material field, belong to the household appliance shell technical field, refer to especially a kind of family expenses Material Field of easy cleaning.
Background technology
The housing of household electrical appliance existing most of adopts the plastic material preparation, and this is mainly because plastics lightweight, corrosion-resistant, and production process is simple, is easy to process different shape, does not basically need machine tooling, once shaped.
But also there are some defectives in plastic casing, and topmost is exactly the ageing-resistant scarce capacities of plastics, in use for some time, just can obviously find out oldization of outward appearance, affects attractive in appearance.Be exactly the undercapacity of Domestic plastic on the one hand, such as at the appliance shell for kitchen use that often cleans, have obvious vestige and occur after use after a while.Be exactly not easy cleaning of plastic casing on the other hand, some spot will could be removed with a large amount of clean-out systems after being attached to plastic casing, and long-time a large amount of use clean-out systems not only affect environment and also can the chemical property of housing be exerted an influence.
Summary of the invention
The purpose of this invention is to provide a kind of easy cleaning material technology scheme, the surface flatness that can improve intensity, ageing-resistant performance and the raising housing of Plastic household appliance shell by the technical program is easy to clean.
The present invention is achieved by the following technical solutions:
A kind of easy cleaning material, its composition is by weight percentage: the titanium dioxide of the polypropylene of 68%-71%, the UHMWPE of 10%-15%, 6%-7%, the filler of 8%-10%, the lubricant of 1%-2%, the pigment of 0.1%-0.5%.
Described UHMWPE processes for carrying out 5-10 minute short-term heating through 150 ℃-180 ℃.
Described lubricant includes exterior lubricant and exterior lubricant.
Described exterior lubricant is 2:1 with the weight ratio of internal lubricant.
Described exterior lubricant is a kind of in higher fatty acid, complex liped, silicone resin, Shi Que and low-molecular-weight resin.
Described internal lubricant is calcium stearate.
Described filler is at least a of glass fibre, mica, talcum powder, silicon-dioxide, aluminium sesquioxide, molybdenumdisulphide and carbon black.
The beneficial effect that the present invention compares with prior art is:
By the technical program, the surface flatness that improves intensity, ageing-resistant performance and the raising housing of Plastic household appliance shell is easy to clean.
Embodiment
Describe by the following examples technical solution of the present invention in detail, should be understood that, following embodiment only can be used for explaining and illustrate technical scheme of the present invention and can not be interpreted as to be restriction to technical solution of the present invention.
Polypropylene (PP) has good electrical property and high-frequency insulation is not subjected to humidity effect, is suitable for making corrosion-resistant mechanical component, and because of its nontoxic, tasteless housing that is widely used in kitchen utensils.But polyacrylic weather resistance and abrasion resistance properties are not enough, are not easy to clean, and it is old that use for some time housing shows, and after repeatedly cleaning, cut are arranged.
In the present invention, come body having the high-intensity while and also improve the surface flatness of goods by acrylic plastering being blended into ultrahigh molecular weight polyethylene(UHMWPE).
Surface hardness and the heat-drawn wire of ultrahigh molecular weight polyethylene(UHMWPE) (UHMWPE) are low, but be the co-continuous phase through the PP/UHMWPE co-mixing system, a kind of blend network of the common formation of the PP molecule of UHMWPE molecule and long-chain, all the other PP consist of a PP network, two networks interweave and are a kind of " linear interpenetrating(polymer)networks ", and wherein the blend network plays skeleton function in material, for material provides physical strength, can occur when being subjected to external impacts than large deformation to play toughness reinforcing effect to absorb extraneous energy.
Concrete preparation method of the present invention is to be by weight percentage: the titanium dioxide of the polypropylene of 68%-71%, the UHMWPE of 10%-15%, 6%-7%, the filler of 8%-10%, the lubricant of 1%-2%, the pigment of 0.1%-0.5% by forming; UHMWPE processes for carrying out 5-10 minute short-term heating through 150 ℃-180 ℃;
Lubricant includes exterior lubricant and exterior lubricant; External lubricant is 2:1 with the weight ratio of internal lubricant;
Exterior lubricant is a kind of in higher fatty acid, complex liped, silicone resin, Shi Que and low-molecular-weight resin; Internal lubricant is calcium stearate;
Filler is that at least a of glass fibre, mica, talcum powder, silicon-dioxide, aluminium sesquioxide, molybdenumdisulphide and carbon black got the raw materials ready.
Wherein polypropylene is the conventional polypropylene of copolymerization.The particle diameter of filler is the 280-300 order.Titanium dioxide is preferably nano material, if not nano material, particle diameter can not be lower than 450 orders.
Polypropylene at the uniform velocity is cooled to after 160 ℃ of-180 ℃ of fusings 150 ℃ add UHMWPE to carry out fully mixing after cooling carry out the PP/UHMWPE granulation.
PP/UHMWPE particle batch mixing is added titanium dioxide, filler, lubricant and pigment in rotating speed is not less than in the mixer of 100 rev/mins batch mixing 5-10 minute; with the material process four screw extruder granulation that mixes, can not adopt two twin screw extruders series connection to use in the situation that requirement condition is high yet.
Melt pressure on forcing machine is controlled at 0.7-1.0MPa, and the rear end of forcing machine vacuumizes, and the rotating speed of forcing machine is 500-550 rev/min.
In various embodiments of the present invention, the preparation method is identical, the distinguishing weight ratio that only forms for material.
