Embodiment 5
See also Fig. 1, the preparation method of embodiment 2 described high-elastic wearproof athletic floor materials may further comprise the steps:
1) batching: carry out the metering of powder weighing and liquid according to embodiment 2 described raw material ratios;
2) high-speed mixing stirs: the material that mixes is dropped in the homogenizer stir, the general stirring at low speed time is 20 seconds, high-speed stirring time 200-250 second, 650 rev/mins of stirring at low speed speed, 1300 rev/mins of high-speed stirring speed, material reaches 85 and just can transfer stirring at low speed to when spending during high-speed stirring, and the surface temperature of compound reaches the 105-110 degree, by the high-speed stirring discharging;
3) Banbury mixer refining is moulded: the powder after the high-speed stirring enters after the banburying chamber of Banbury mixer the powerful rotor that is had a protruding wing by two of Banbury mixeies and shears, the rotating speed of two rotors is respectively 40 rev/mins, the speed ratio of two rotors is 1: 1.156, the volume of Banbury mixer is 100 liters, temperature is to the 145-150 degree when refining is moulded, refining is every batch of 200-300 second the time of moulding, and makes material constantly be subjected to powerful the shearing.The top of banburying chamber has a weight to push down, and intensive is mixing to produce heat of friction and shear heat with friction to material owing to being subjected to, and make the plasticizing of material resin rapidly, and the additive thorough mixing in the prescription forms blocky gel;
4) mill plasticizing: two mills of series connection usually in the Production Flow Chart are to be used for further mixing, mixing plasticizing equipment, and with further plasticizing and be incubated for next technology stores of fused sizing material fully of Banbury mixer, guaranteed quality is even; 4-5mm is generally got in the running roller gap, the front and back roller temperature difference 10 degree, roller controlled temperature 130-150 degree;
5) screw extrusion press filters feeding: will filter feeding by twin screw extruder through the sizing material of Banbury mixer preplasticizing, the barrel zone temperature of screw extrusion press generally is controlled at the 130-165 degree, screw rod will lead to water coolant and prevent burnt material, 80-120 purpose filtering net when producing the glued membrane use, forcing machine fuselage and die head carry out the adjustment of plasticizing effect by 4 sections temperature controls by controlled temperature and compression ratio;
6) rolling press moulding: evenly enter the rolling press gap by waving feeding machine through the bar-shaped sizing material after the twin screw extruder filtration, adjust the thickness degree of film by temperature, speed and the roller gap of controlling each roller, four-roll calender is just rolled the film that becomes to need during by three gaps, if produce thin goods then need further stretching action by pull roll.Four-roll calender is owing to the effect of sizing material at the separating force in roller gap, and the two ends temperature difference of roller and the control of products of different specifications need compensate the thickness degree error that rolling press causes.This line configuration roll bending and anti-roll bending device, camber design and axle skewing mechanism; The temperature of common four rollers is respectively the 165-170 degree, the 170-175 degree, and 175-185, the 170-175 degree, the 4th roller speed is 12-18M/MIN, Transmission Ratio Control scope 1.2-2.0.
7) deflecting from device heat draws: the film behind the calendering formation is thin through deflecting from device heat and draw or drawing by speed ratio, doff roll by two groups altogether the rollers of the logical deep fats of the six roots of sensation form temperature 130-160 degree, speed ratio 1.1-2.5;
8) cooling and shaping: will carry out cooling and shaping through the film that deflects from the device aftershaping, cooling roller general three groups totally nine rollers form, the logical water coolant of roller central authorities, water temperature needs control according to production specification, is generally the 5-8 degree.If produce summer, the envrionment temperature height then needs to prevent the generation of the globule, the about 1-2 of the temperature correlation of shaping time and typing minute, need fully, and prevent follow-up dimensional change contraction;
9) side cut is curled: batch by certain length by the friction-type reeling machine at last;
10) high temperature is fitted: embryophoric membrane one deck that step 9) is made is as facial mask, another layer is as counterdie, add in addition that fiberglass gridding cloth fully heats or preheating after, the place fits together three layers simultaneously at the applying embossing device, the front is an embossing steel rider that particular surface grass-like lines is arranged, the bottom surface is a rubber rollers, to add very big pressure between two rollers during applying, nearly the embryophoric membrane and the screen cloth of molten state combine, oil pressure is generally adopted in the promotion of grain roller, it is the oil cylinder of 80-100 that respectively there is a diameter at the two ends of roller, oil pressure generally is adjusted at 3-5Mpa, binding temperature 160-180 degree, doubling roller speed 8-15M/Min, described embossing steel roller faces has the grass-like lines.
The preparation method of the described high-elastic wearproof athletic floor material of the application has following advantage:
1) the high-speed stirring process makes and produces violent friction between material and paddle, agitation vat and the material, temperature rises rapidly, powder body material and liquid additive are absorbed fully by polyvinyl chloride resin under molecular thermalmotion and sufficient stirring action, add TPU polyurethane elastomer resin in the embryophoric membrane prescription, utilize the high-wear resistance of urethane that prescription is carried out modification, the surface layer that forms product has the super wear resistance energy, guarantees to produce enough frictional force, satisfy the athletic floor requirement, finish athletic performance.
2) screw rod filters the forcing machine feeding: utilize the die head strainer filtering effect of screw rod extruding filter, remove the impurity of raw material process, guarantee that product does not have pin hole and sand holes etc. to cause the surface quality defect of athletic floor at last.
3) utilize high temperature lamination joint technology: the embryophoric membrane that will meet use properties is fitted with the glass fiber mesh of the ultralow shrinking percentage of high strength behind the rigging machine heat fusing, the embossing device place by the hydraulic coupling set two-layer embryophoric membrane and layer of glass screen cloth while high temperature lamination joint, form the finished product of homogeneous, delamination does not take place in the fastness that guarantees in use to fit, the front of embossing device is one particular surface grass-like lines steel embossing roller, be used for strengthening the frictional coefficient on athletic floor surface, guarantee to produce enough frictional force, finish athletic performance.
