    • Method for joining plastic materials and products made of materials of various kind, such as natural leather, regenerated leather, natural hide, synthetic hide, fabrics of any kind, wood and the like, without the aid of bonding agents or adhesive materials, for obtaining products of various kind such as for example chairs, settees, furniture, and relative component elements and furnishings products of various kind, and articles for different uses, etc.. Method in which, before the contact with the molten plastic materials, the materials different than the plastic materials are treated, on to their outer surface of contact with such molten plastic materials, with a pre-treatment composition formed by ethylic alcohol, ammonium nitrate and water, at different and variable ratios depending on the type of the materials to be treated, with the following ratios by weight with respect to the weight of the composition : 1) ethylic alcohol : from minimum 30% by weight to maximum 60% by weight; 2) ammonium nitrate : 30% by weight; 3) water, particularly demineralized water : from minimum 10% by weight to maximum 40% by weight, so as to obtain a temperature decrease of the treated outer surface of said different materials, thanks to the reaction of the ammonium nitrate in presence of the ethylic alcohol-water mixture, which determines an evaporation of the ammonium nitrate and the developing of cooling. The molten plastic material is added with at least a cross-linking agent, preferably hexantriol, and injection moulded over the treated outer surface of the different materials, and cooled by means of said pre-treatment composition.
    • 无需借助粘合剂或粘合剂材料接合塑料材料和天然皮革,再生皮革,天然皮革,合成皮革,任何种类的织物,木材等各种材料制成的产品的方法,用于获得 各种产品,例如椅子,椅子,家具,相关元件和各种家具产品,不同用途的物品等。其中,在与熔融塑料材料接触之前,材料不同 与塑料材料处理相比,其外表面与这种熔融塑料材料接触,并用乙醇,硝酸铵和水形成的预处理组合以不同的和可变的比例取决于材料的类型 相对于组合物的重量,按以下重量比进行处理:1)乙醇:至少30重量%至最大60重量%; 2)硝酸铵:30重量% 3)水,特别是软化水:从最小10重量%至最大40重量%,以便获得所述不同材料处理的外表面的温度降低,这是由于硝酸铵在 乙醇 - 水混合物,这决定了硝酸铵的蒸发和冷却的发展。 在熔融的塑料材料中加入至少一种交联剂,优选为六聚物,并在不同材料的经处理的外表面上注射成型,并通过所述预处理组合物进行冷却。
