Description

Coiled material and preparation method thereof, prefabricated coiled material and processing method thereof, spliced coiled material and application

Technical Field

The invention relates to the field of runway structures, in particular to a coiled material and a preparation method thereof, a prefabricated coiled material and a processing method thereof, an assembled coiled material and application thereof.

Background

The conventional synthetic material track is mainly divided into a polyurethane plastic track and a prefabricated rubber track. The polyurethane plastic track is made of polyurethane glue (usually AB double-group glue), filling colloidal particles, surface layer ethylene propylene diene monomer particles and the like, and is directly poured on an asphalt concrete base layer after the polyurethane glue and the filling colloidal particles are uniformly mixed by adopting a field pouring process, and the surface layer ethylene propylene diene monomer particles are scattered as an anti-skid layer before rubber curing. The polyurethane glue is glue containing urethane groups and isocyanate groups in molecular chains, has high reactivity due to the fact that the polyurethane glue contains strong-polarity isocyanate and urethane groups, can be solidified at room temperature, is mixed in proportion on a construction site, is added with colloidal particles and other auxiliary materials and is stirred into a sticky state, and is paved on the basis of asphalt/cement, so that the raw materials are subjected to chemical reaction and solidification forming. If the weighing of the materials of each component is inaccurate in the construction process, the chemical reaction degree of the materials is influenced, and the physical performance and the chemical performance of the paved playground surface layer are unqualified; in addition, during the laying process, when the material is not cured to a certain degree, once it rains, the layer of polyurethane material is likely to be scrapped. Furthermore, organic isocyanate compounds are very reactive in chemical nature because they contain isocyanate groups (NCO, formula — N ═ C ═ O) which are highly unsaturated bonds. In a period of time after the polyurethane elastomer product is synthesized, a trace amount of unreacted NCO still exists in the system, and the reaction still needs a long time to be completely carried out in a solid state. As a result, there are traces of free NCO groups in the polyurethane material. The high volatilization period is within 3 years, and toxic gas can be quickly released in hot weather or ultraviolet irradiation, so that the possibility of harming the body health of sporters exists.

The prefabricated rubber track is an environment-friendly rubber coiled material with a double-layer integrated structure, can be designed into a rubber coiled material with certain thickness, width and length or a block finished rubber coiled material in a factory in advance according to requirements, and is transported to a construction site to be bonded and laid on asphalt/cement of an area to be laid. The construction process of the prefabricated rubber track (or court) is as follows: an adhesive layer with a certain thickness (about 1 mm) is coated on an area to be paved, and then the prefabricated rubber coiled material or the prefabricated sheet material is sequentially paved on the adhesive layer in a roll-to-roll mode. The seams between the coiled materials (or the sheets) need to be flat, tight and seamless, the height difference cannot exist, and the seams need to be filled with adhesives to avoid separation and foaming of the runway surface layer caused by water inflow from the seams. Therefore, it is necessary to flatten the transverse and longitudinal joints between the rolls (or sheets) by using weights when the pavement is performed, and remove the weights after the adhesive is cured (about 6 hours or more).

The design standard of the inclination of slope of a standard 400-meter track field is generally 0.8 percent of the track, which is not higher than 1.0 percent nor lower than 0.5 percent; 0.4% of semicircular area and not less than 0.3%; the auxiliary area is about 0.5 percent. Meanwhile, the international association for track and field association has the requirements on the flatness of the foundation, namely, the aluminum alloy ruler with the length of 3 meters is taken as a standard, unevenness exceeding 3mm cannot be formed in the distance of 3 meters, and the compactness reaches more than 95%. It can be seen that for paving cement or asphalt tracks on an area to be paved, the requirements for flatness, inclination and minimum thickness of the surface of the area to be paved are very strict. At the same time, in order to meet the requirement of error range, necessary correction is carried out on the layer laid at the end. Therefore, whether the existing polyurethane plastic track or the prefabricated rubber track has higher technical requirements and laying requirements for constructors in laying construction, the former has higher familiarity on the physicochemical properties of chemical products, but laying still consumes a large amount of time, and the raw materials of the track have certain toxicity and can still harm the body health of sporters after certain time after laying is finished; the seam between the coiled materials must be well processed by the splicing method, splicing must be performed sequentially, the whole runway cannot be spliced simultaneously, and the whole splicing process is time-consuming and labor-consuming. In addition, the requirements of the both on climate in laying construction are strict, for example, construction cannot be carried out absolutely in rainy days, and construction cannot be carried out even if the temperature is too low, so that the construction period is often prolonged.

it can be seen that the coiled material of the examples and the comparative examples provided by the invention can meet the national standard in both raw material composition test and performance data.

The prefabricated coiled material provided by the embodiment 1 is assembled, and the assembly effect is shown in fig. 4. The spliced coiled material of the embodiment shown in fig. 4 has certain flexibility, can be bent by 5-15 degrees, improves the flexibility of the coiled material and reduces the internal stress of the coiled material, so that the coiled material is not deformed after being bent and has no folds.

The prefabricated coiled material provided by the embodiment 2 is assembled, and the assembly effect is shown in fig. 5. As shown in figure 5, the assembled coiled material has the advantages that the instant cutting effect is good, the surface flatness between the coiled materials is high, the buckle connection is tight, a gap formed by connecting the buckle parts of the two adjacent coiled materials can not be seen almost, the assembled coiled material still has a good splicing state even if being placed for 6 months, the flexibility of the coiled material is improved by the formula of the coiled material, the internal stress of the coiled material is reduced, the difference of shrinkage coefficients between the double-layer coiled material is small, the good connection state can be still kept even after long-time oxidation and aging, and the whole coiled material and the connection part are not deformed or warped.

In addition, the cooperation uses the marginal "T" shape buckle of coiled material, and a single buckle junction just has 7 contact surfaces, increases substantially the area of contact of buckle junction and the frictional force of contact department, and the atress of even block structural connection department further improves the zonulae occludens's of buckle junction degree, can realize not having the glue to accomplish the work of mating formation under the prerequisite of assembling, has still reduced the injured risk to the roll material user of assembling, improves the motion security to the user.

The prefabricated coiled material provided by the comparative example 1 is assembled, and the assembly effect is shown in fig. 6. As shown in fig. 6, after six months of the completed assembly, there were a lot of gaps at the joints, and tight connection between the assembled coils could not be achieved because the assembled coils having a poor flexibility, a good oxidation resistance and aging resistance, and a good combination could not be obtained by using coils having no optimized formulation. Even if effective compounding is realized during laying, after the assembly is completed for six months, the coiled materials are oxidized and aged, the difference of the contraction coefficients between the double-layer coiled materials is large, the warping of the joints between the coiled materials is obvious, and the buckles at the assembly part are easy to deform to cause incompactness. Safety accidents may occur during the use of the user.

Furthermore, because the buckles at the cutting positions of the coiled materials in the comparative example are dovetail groove-shaped buckles, compared with the method that 7 contact surfaces of T-shaped buckles in the embodiment are connected in a clamping structure, the connection effect of the clamping structure between subsequent coiled materials is poor due to the reduction of the contact surfaces and the reduction of the friction force of the contact surfaces, so that the spliced coiled materials which are reliably and stably connected, are not easy to separate, and are not easy to warp and deform at the connection positions can be obtained only by matching and carrying out the clamping structure connection with large contact area on the premise of simultaneously meeting the composition of the coiled materials provided by the invention.
