Description

The damping plastics floor for outdoor use manufacturing process

The present invention relates to a kind of pavement, specifically a kind of damping plastics floor for outdoor use is modern senior pavement.It can absorb impact energy effectively, with guarantor's comfortable and safe in when motion.Mainly be applicable to the place in place, children amusement park and nursery, senior rooms etc. such as laying gymnasium, sports training ground, golf, tennis.

Domestic most employing cement, plastics, plank and palm fibre pad are made terrace at present, and the problem of existence is: 1. all can not guarantee personal safety effectively, 2. also be unfavorable for bringing into play to greatest extent physical culture personnel's achievement.The patent of not having this respect by retrieval abroad have and use the damping terrace, but cost is too high, and is undesirable in a word.

The objective of the invention is:, for eliminating the pollution of waste old (mainly being junked tire), be the prescription and the manufacturing process of the damping plastics floor of primary raw material with the waste old simultaneously and provide a kind of to environment for addressing the above problem.

Realize that the technical measures that the object of the invention is taked are:

Fig. 1 is technological process of production figure of the present invention

The technological process of production: referring to Fig. 1

Clean 1: waste and used rubber tyre a is put into cleaning machine clean, remove foul, Taking-up is dried;

Slitting 2: will clean the junked tire a that dries and put into cutting machine and cut into inch strips;

Pulverize 3: the junked tire bar is put into disintegrating machine, and (opening of ZKC-5609 type is rolled The cartridge type disintegrating machine) pulverizes in;

Screening 4: the rubber grain after will pulverizing (being called for short the glue chaff) is crossed 8-32 The purpose sieve aperture screens;

Activation process 5: get glue chaff 72-90kg, put into gasoline No. 120 In, till submergence glue chaff, to soak 2-4 minute, taking-up is dried, and puts into stirring In the device, add activator and mix thoroughly, left standstill 3-10 minute, repeatedly wash with clear water 2-3 time, dry the prescription of activator after cleaning: water 40-50kg, inferior Sodium chlorate 12-15kg, hydrochloric acid 0.2-0.25kg;

Polymerization 6: toluene diisocyanate b and polypropylene ether glycol c are pressed the prescription polymerization Become performed polymer, its technology for earlier with the polypropylene ether glycol 80-130 ℃ with Vacuum is to dewater 1-3 hour in retort under the 5mmHg, is cooled to then 40 ℃, Slowly add toluene diisocyanate, reaction 1-3 is little under vacuum or purity nitrogen protection The time be cooled to the room temperature discharging, sealing lucifuge stored for future use;

Moulding (or cast-in-situ) 7:

A. in agitator, add successively the performed polymer after the polymerization, white carbon g, pigment h, 2,6-BHT d, the plumbous e of 2 ethyl hexanoic acid, phenylmercuric acetate f, under 80-100 rev/min with material stirring 5-15 minute that adds, compound is poured in another agitator that has dropped in advance the 8-32 order glue chaff after activated, stirred 5-18 minute rapidly, the main compound that is about to is poured in the frame that mould or place encloses, at 0.1kg/cm²Pressure, room temperature or the lower curing and demolding of heating;

B. also can be by formulation weight, take by weighing respectively each component, in agitator, drop into successively toluene diisocyanate and polypropylene ether glycol, white carbon, pigment is (such as iron oxide red, chrome green etc.), 2, the 6-BHT, 2 ethyl hexanoic acid lead, phenylmercuric acetate, under 80-100 rev/min with material stirring 5-15 minute that adds, make mixing of materials even, then compound is poured in another agitator that has dropped in advance the 8-32 order glue chaff after activated, stirred rapidly 5-18 minute, immediately compound is poured in the frame that encloses in mould or place, at 0.1kg/cm²Pressure, room temperature or the lower curing and demolding of heating, when adjusting cold curing according to prescription Between can be controlled at 1-6 hour, the heating cure time can shorten about 50%;

Post processing 8: at room temperature deposit a week then completion of cure namely go out finished product 9.

Being designed to mould according to the needs in different places has to produce single, double layer The prefabricated component of difformity and size, when making double-deck floor material, the component of lower floor In remove white carbon and pigment, the glue chaff adopts 32 order granularities, all the other prescriptions with produce Technology is identical with individual layer.

The effect of each component is in this prescription:

Toluene diisocyanate (TDI80) is the master who forms the polyurethane binding agent Want raw material; Polypropylene ether glycol (PPG-2000) is with forming poly-ammonia after the TDI reaction Base formic acid fat binding agent, its molecular weight is 2000, Reaction equation is:

2 ethyl hexanoic acid lead and phenylmercuric acetate are catalyst, and catalytic effect is better when share, and utilizes the close electrical characteristics of catalyst, make the carbimide base change the excessive attitude of high energy into and strengthen reaction from the resonance stable state;

2, the 6-BHT, or 1010, being commercially pure antioxidant, effect is the ageing-resistant performance that improves product;

The effect of white carbon is to improve the diffusivity of pigment in colloid, makes pigment distribution even;

The effect of activation: utilize the active chlorine in the activator, make glue chaff surface chlorination, to strengthen its surface polarity, cohesive force strengthens when making moulding;
