Abstract
The present invention discloses an inspection well cover and its preparation, it is made by mould pressing a material composed of waste plastics (30-60), waste coal slag (30-60), waste machine oil (1-5), coupling agent (0.5-3), nanometre material (0.1-3). Its preparing process includes: preparing plastic matrix, preparing sand mass, mixing, synthesizing, mould-pressing into form, pressure retaining, and demoulding. Advantages includes: low cost cerrosion resistant, ageing resistant, solving the pollusion problem of waste material.
Description
Affiliated field
The present invention relates to a kind of is the inspection shaft lid of main material preparation with waste plastics, waste coal slag and used oil.
Background technology
The present inspection shaft that uses is stamped iron, cement, reinforcing bar, concrete and Composite Preparation and forms, although cast iron inspection shaft lid has certain anti-rolling and the shock loading ability, but because scrap iron can reclaim, this often becomes the target that the lawless person steals, and brings very big loss to country.Replace with cement steel concrete: this product is cementing agent with cement, is that reinforcing material forms through batch mixing casting natural curing with reinforcing bar, rubble, sand.Intensity can satisfy instructions for use: its major defect is that weight is too big, is awkward, and price is also than cast iron height, and property is crisp.Reinforced concrete well lid is applicable to the occasion that those are not often opened: the well lid that road is arranged is also improper, and is simultaneously also not attractive in appearance, is matrix with epoxy resin and unsaturated polyester (UP), and glass fiber is a packing material, and reinforcing bar is that skeleton is through cast molding.The well lid intensity that this method is produced can satisfy instructions for use in a short time.But cost is than the highly difficult 1/3-2/3 of casting iron well lid, and make urban engineering project be difficult to accept: this in addition well lid weight is too light, very easily breaks away from original position on the fast traffic lane along with the impulse force of automobile, brings bigger hidden danger for vehicle and pedestrian.The natural aging life-span that glass is born is being subjected under the situation of various fatigue loads generally at 3-5, will speed up the aging of it.
Summary of the invention
The invention provides a kind of fully utilize waste plastics and waste coal slag and have that the cost of material is low, anti-corrosion, ageing-resistant inspection shaft lid and preparation method thereof.
Inspection shaft lid of the present invention and inspection shaft seat are to be made through compression molding by waste plastics, waste coal slag, used oil, coupling agent, nano material, and its weight consists of: waste plastics 30～60, waste coal slag 30～60, used oil 1～5, coupling agent 0.5～3, nano material 0.1～3.
The inspection shaft lid can be round or square, and its bottom is provided with reinforcing rib.
Preparation method of the present invention:
1) plastic substrate preparation
Waste plastics is carried out drying, fragmentation;
2) sand body preparation
The waste coal slag is pulverized, carried out activation processing with coupling agent then;
3) mix
Plastic substrate, sand body and used oil, nano material are mixed;
4) synthetic
Mixture is placed in the machine oil to heat up synthesizes;
5) go into mold pressing system;
6) pressurize;
7) demoulding.
It is that primary raw material is made the inspection shaft lid and is beneficial to comprehensive utilization three wastes resource that the present invention adopts waste plastics, waste coal slag and used oil, and its waste coal slag adopts coupling agent to carry out activation processing, is convenient to bonding with plastic substrate.Add chemistry and the physical property that nano material can change composite material in the manufacturing process.Improve the working strength and the life-span of finished product.Mixture heated up in synthesizer synthetic be convenient to the waste coal slag and fully coat and plastify.
The specific embodiment
The waste plastics of collecting is cleared up to remove contained non-plastics class material and different types of waste plastics is classified: use for ease of follow-up preface, must carry out drying and fragmentation waste plastics; Because the antiquated sand table containing one deck water glass inert coating, can hinder bonding with plastic substrate; Therefore, before use, should carry out surface activation process, employed activation method has physics method and chemical method, chemical method is mainly based on coupling agent treatment, for improving the flowability of material, increase plasticity, improve combined coefficient, the composite additive part that is absolutely necessary, each material can obtain the inspection shaft lid or the inspection shaft seat of required form under the effect of special synthesizer after mixing, the product after the moulding needs pressurize typing certain hour to take off examination up to product, must place naturally after 12 hours and could use.The inspection shaft lid is put in the inspection shaft seat during use.
