PU sports floor capable of maintaining curing speed
The invention discloses a PU sports terrace capable of maintaining curing speed, and relates to the field of PU sports terraces, the PU sports terrace comprises a middle layer, an upper coating and a surface coating; the middle layer comprises the following components in parts by mass: 10-15 parts of synthetic rubber particles, 5-7 parts of polyurethane particles and 1-2 parts of an adhesive; the upper coating comprises the following components in parts by mass: 5-10 parts of polyurethane emulsion, and a proper amount of a modified curing agent and an auxiliary agent; the surface coating comprises the following components in parts by mass: 5-10 parts of polyurethane emulsion, 1-3 parts of organic filler, 0.5-1 part of organic pigment and a proper amount of modified curing agent; the modified curing agent is prepared from the following components in parts by mass: 1 to 3 parts of dicyandiamide, 0.5 to 1.5 parts of triethyl benzyl ammonium chloride, 3 to 5 parts of formaldehyde solution, 0.5 to 1 part of epoxypropane, 2 to 4 parts of nitrile rubber buna particles, 1 to 2 parts of polyvinyl chloride particles and chloroprene rubber. The curing agent can maintain a high curing speed, is low in modification cost and long in shelf life, and can maintain good use performance.
本发明公开了一种具备保持固化速度的PU运动地坪，涉及PU运动地坪领域，包括：中间层、上涂层和面涂层；中间层包括：按质量份计的合成橡胶颗粒10‑15份，聚氨酯颗粒5‑7份，黏结剂1‑2份；上涂层包括：按质量份计的聚氨酯乳液5‑10份，以及适量改性固化剂和助剂；面涂层包括：按质量份计的聚氨酯乳液5‑10份，有机填料1‑3份，有机色料0.5‑1份，以及适量改性固化剂；改性固化剂包括：按质量份计的双氰胺1‑3份，三乙基苄基氯化铵0.5‑1.5份，甲醛溶液3‑5份，环氧丙烷0.5‑1份，丁晴橡胶颗粒2‑4份，聚氯乙烯颗粒1‑2份，氯丁橡胶，该运动地坪对固化剂进行改性，使得改性固化剂与聚氨酯乳液时反应时，可保持较快的固化速度，且改性成本低，保质期长，能维持良好的使用性能。
