The invention discloses an adhesive for invisible car clothing. The adhesive comprises a propylene polymer obtained by copolymerization of a monomer mixture, the monomer mixture comprises: (a) 8-30 wt% of a propylene monomer which has a glass transition temperature of 0-80 DEG C when constituting a homogeneous polymer and does not have a crosslinkable functional group; (b) 2 wt%-7 wt% of a monomer containing hydroxyl groups; (c) 0.5 wt% to 5 wt% of a monomer containing nitrogen atoms; (d) 10 wt% to 25 wt% of a macromonomer, which is a high molecular weight monomer having a polymerizable functional group and a number average molecular weight of 3000 to 10000; the glass transition temperature of a homogeneous polymer formed by the polymer is 30-120 DEG C; and (e) at least one propylene monomer other than (a) to (d). The adhesive for the invisible car cover is small in rolling ball initial adhesion (ball adhesion test) and high in initial adhesion force; the adhesive has good adherence to a TPU base material, does not cause adhesive residue under the condition of strong adhesive force, and is not easy to debond and strip after being used for a long time.

    本发明公开了一种隐形车衣用粘着剂包含由单体混合物共聚而获得的丙烯类聚合物;所述单体混合物包含:(a)8wt%~30wt%的丙烯类单体,其构成均质聚合物时的玻化温度为0℃~80℃,并且不具有交联性官能基团;(b)2wt%~7wt%的含有羟基的单体;(c)0.5wt%~5wt%的含氮原子单体;(d)10wt%~25wt%的具有能够聚合的官能基且数均分子量为3000~10000的高分子量的单体即大单体;其构成的均质聚合物时的玻化温度为30℃~120℃;(e)至少一种上述(a)~(d)以外的丙烯类单体。本发明的隐形车衣用粘着剂滚球初粘(球粘试验)小,且初期粘接力强;该粘着剂对TPU基材密着性好,在强粘接力条件下不会残胶,长时间使用不易脱胶剥离。
