    • Provided is a resin composition for coating, including: 35-65 wt % of a high-molecular weight polypropylene resin (A) having a weight average molecular weight of 100,000-300,000 and an isotactic chain molar fraction, L, of 0.30-0.70; 30-60 wt % of a low-molecular weight polypropylene resin (B) having a weight average molecular weight of 10,000-50,000 and an isotactic chain molar fraction, L, of 0.30-0.70; and 0.1-5.0 wt % of a highly crystalline, low-molecular weight polypropylene resin (C) having a weight average molecular weight of 5,000-50,000 and an isotactic chain molar fraction, L, of 0.70-0.75. The polypropylene resin composition for coating is amenable to spray coating while avoiding a need for a complicated process such as discharge treatment, flame treatment or acid treatment of a polypropylene substrate, in the absence of chlorine, and is effective for forming a coating film having excellent scratch resistance and adhesive property and showing no tagging property.
    • 本发明提供一种涂料用树脂组合物,其包含:35〜65重量%的重均分子量为100,000〜300,000,全同立构链摩尔分数L为0.30〜0.70的高分子量聚丙烯树脂(A) 30-60重量%的重均分子量为10,000-50,000的低分子量聚丙烯树脂(B)和全同立构链摩尔分数L为0.30-0.70; 和0.1-5.0重量%的重均分子量为5,000-50,000的高度结晶的低分子量聚丙烯树脂(C)和0.70-0.75的全同立构链摩尔分数L。 用于涂布的聚丙烯树脂组合物适于喷涂,同时避免在不存在氯的情况下需要诸如聚丙烯基材的放电处理,火焰处理或酸处理等复杂的工艺,并且有效地形成具有优异的涂膜 耐刮擦性和粘合性,并且不显示标签性。

    • A laminar coating material, for example for use as flooring, comprises: a polyolefin matrix having a first colouring; and a phase of particulate elastomer material, such as vulcanized rubber, dispersed in the polyolefin matrix and comprising particles of at least one second colouring, which contrasts with the colouring of the polyolefin matrix. Preferably, the particulate elastomer material in question is in turn obtained starting from a plurality of intermediate mixes, each comprising a polyolefin matrix having a first colouring, in which there is dispersed a respective particulate phase comprising particles of a respective second colouring. The respective second colouring is different for each intermediate mix and contrasts with the aforesaid first colouring. The intermediate mixes are mixed together so as to form a mixture used for obtaining the final material, preferably by means of granulation, formation of a bed of granules, and isostatic pressing of the bed thus formed.
    • 层状涂层材料,例如用作地板,包括:具有第一着色的聚烯烃基质; 以及分散在聚烯烃基质中并包含至少一种第二着色的颗粒的颗粒弹性体材料(例如硫化橡胶)的相,其与聚烯烃基质的着色形成对比。 优选地,所讨论的颗粒状弹性体材料又从多个中间体混合物开始获得,每个中间体混合物包含具有第一着色的聚烯烃基质,其中分散了包含各自第二着色颗粒的相应颗粒相。 相应的第二着色对于每个中间体混合物是不同的,并且与上述第一着色形成对照。 将中间体混合物混合在一起,以形成用于获得最终材料的混合物,优选通过造粒形成颗粒床,以及如此形成的床的等静压。
