Description

Plastic cement ground cushion spray plane glue

Technical field

The present invention relates to a kind of plastic cement ground cushion spray plane glue.

Background technology

Plastic floor has certain elasticity, Ginkgo Biloba Leaf Extract and ageing-resistant ability, is the optimal movement field floor material of generally acknowledging in the world.

Advantage like plastic cement race track has:

Round-the-clock use: any season and the temperature difference, all can keep the quality of high level, more can use immediately behind the rain, increase the time of utilizing, improve the place rate of utilization.

Elasticity: have the elasticity and the bounce of appropriateness, can reduce the consumption of muscle power, promote the contest achievement.

Surging force absorbs: appropriateness absorbs foot impacts power, reduces sport injury, practises for a long time and compete all suiting.

Weathering resistance: can be because of the pollution of ultraviolet ray, ozone, acid rain is not faded, efflorescence or softening, and can keep for a long time

Its bright colour.

Wear resistance: wear resistant is less than 2.5%, and it is long-time to satisfy school and college, the needs of high frequency of utilization.

Resistance against compression: can can't not recover elasticity because of the weight of track and field equipment.

Anti-nail power:, also can not receive spikes or block and destroy at hundred meters the most used starting lines of stressed maximum.

Shock-resistance: have tough elastic layer and impact plies, can absorb powerful impact, the surface can be not impaired.

Flatness: use self-leveling material during construction, have an even surface, can meet smooth especially competition area requirement.

Cementability: special construction is handled, and bonding force is strong, can suppress moisture content and rise, and does not have phenomenons such as bubbling, peel off.

Security: can prevent the sport injury of falling and being taken place.

Economical: easy to maintenance, saving overhead charges.

Color: special-purpose snappiness EPDM and PU particle, surface color is soft, and the particulate state top layer prevents dazzling

The reflection of light, attractive in appearance durable, and can adopt the multicolour collocation.

Gymnastics venue land used pad adopts the plastic cement ground cushion more at present, and this type ground cushion great majority are that PVC material or PE highly foaming polyethylene material are processed.PVC (being SE) ground cushion is generally processed by soft PVC, and soft pvc has snappiness, but feel is sticking, albinism can occur at the flexion place after when using one section.Especially the gymnast the exercise in, through regular meeting over the ground face the impact than great is arranged, use this type ground cushion surface folding line to occur.The ground cushion of PE (being highly foaming polyethylene) material is softer, touches the wax sense, and is wear-resisting.

Also having some ground cushions is to adopt the EVA resin to process, and it is an Injecatable EVA Copolymer, and general vinyl acetate between to for plastic (VA) content is 5%～40%.Compare with Vilaterm; EVA is owing to introduced Vinyl Acetate Monomer in molecular chain; Thereby reduced high-crystallinity; Improve snappiness, shock resistance, filler intermiscibility and thermally sealed performance, be widely used in fields such as foam material, functional canopy film, packing film, hot melt adhesive, electric wire and toy.It is a kind of more common chemical materials, through one step foaming certain shock absorption is arranged usually.

How a kind of plastic cement ground cushion spray plane glue of safety and environmental protection is provided, and is a new problem of plastic cement ground cushion industry.

Summary of the invention

The technical issues that need to address of the present invention just are to overcome the defective of prior art, and a kind of plastic cement ground cushion spray plane glue is provided, and it is the healthy floor of a kind of environmental protection; It is quick, easy to construct, and can round-the-clockly use, and maintains, keeps in repair easy; The durable life-span is long, helps to realize optimum economic benefit.

For addressing the above problem, the present invention adopts following technical scheme:

The invention provides a kind of plastic cement ground cushion spray plane glue, said spray plane glue is prepared from following materials of weight proportions:

Polyether glycol 210:8-12 part; 52 clorafins: 3-5 part; Pure MDI:4-6 part; Toluene: 1 part;

The preparation method is: with the disposable input reaction kettle of all materials, through steam heating, at the uniform velocity stir, controlled temperature is at 80-90 ℃; Insulation detected NCO content and reaches about 6% more than 5 hours, cooling, blowing, packing.

Preferably, said spray plane glue is prepared from following raw materials according:

Polyether glycol 210:10 part; 52 clorafins: 4 parts; Pure MDI:5 part; Toluene: 1 part;

The preparation method is: with the disposable input reaction kettle of all materials, through steam heating, at the uniform velocity stir, controlled temperature is at 80-90 ℃; Insulation detected NCO content and reaches about 6% more than 5 hours, cooling, blowing, packing.

It is quick, easy that the present invention constructs, can round-the-clockly use, the maintenance, the maintenance easy, the durable life-span is long, helps to realize optimum economic benefit.

The plastic floor elasticity that the present invention is affected is moderate stable, and elastic layer provides absolute security, rebound resilience, makes the floor have sticking power more, makes sole close proximity to ground constantly, the anti-skidding and transmission strong impetus of following one's bent.Good elasticity is closed energy-conservation playing a very good protection to athletic shank; Avoided sport injury effectively; The strong anti-skid of wear resistance is better, and the effect that have stable place size, increases the service life is never shunk the floor; Performance is more stable, can bring into play athletic level better.

The moving floor movements characteristic that the present invention makes is splendid, and kinematic coefficient is an optimum value, and athletic ability is represented heartily, for starting, pedal exercises such as jumping, sliding steps, braking powerful guarantee is provided.

Advantage of the present invention has:

1, environmental protection, nontoxic, "dead" pollution belongs to Green Product, but resource recycling.

2, wear-resisting, high molecular abrasion-proof layer long service life.Because super wear resistance, so at the bigger market of flow of the people, supermarket, the vehicles etc., plastic floor more and more receives an acclaim.

3. anti-skidding, on-slip property is strong, meets water and sends out puckery, can remove the old man, children's trouble and worry.So the softer elasticity of plastic floor quality is fine, under the impact of weight, better elastic recovery is arranged, so can significantly reduce personnel's the tumble injury that slides into, destroying for heavy impact simultaneously also has very strong recovery of elasticity.Can not cause damage.

4. light weight, light building material can alleviate the floor load-bearing significantly.

5. pattern is novel, and multiple pattern is available, and is lucuriant in design, true to nature naturally, assembly group pattern moulding arbitrarily, outstanding personal color.

6. absorbing sound and lowering noise,, not only do not produce noise, but also eliminate noise, reach quiet effect, can create a comfortable work living environment.

7. safe, insulation, fire-retardant, corrosion-resistant, acid and alkali-resistance, the surface is as good as shape.Fire prevention: plastic floor can reach the fire prevention of b1 level, and this also is a building materials fp highest standard.

8. moistureproof, chance water is indeformable.

9. feel is comfortable, and is flexible.The wearing layer on plastic floor top layer has special anti-skid, and compares with common earth material, and plastic floor feel under the situation of sticking water is more puckery, more difficult sliding into.

10. anti-impact force, the flexible usage period is long.

11. convenient and quick construction, the reduction of erection time.

12, sweep conveniently.The foundation skirting also can be used with this floor rolling in addition, makes things convenient for the corner health to sweep, and exempts from waxing, reduces later maintenance cost.
