    • The present invention aims to provide a rigid polyurethane resin for cutting, which has high heat resistance, no scorching, and reduced expansion due to absorption of moisture in the air. The rigid polyurethane resin-forming composition (P) for cutting of the present invention includes: a polyol component (A); an isocyanate component (B); an inorganic filler (C); and a dehydrating agent (D). The polyol component (A) includes: 45 to 99% by weight of a polyphenol (j) alkylene oxide adduct (a), the polyphenol (j) having k functional groups where k is an integer of 2 or 3; and 1 to 55% by weight of a polyol (b). The polyphenol (j) alkylene oxide adduct (a) includes a total of not more than 39% by weight of a polyphenol (j) alkylene oxide adduct (ak) with at most k moles of alkylene oxide, based on 100% by weight of the polyphenol (j) alkylene oxide adduct (a), and has a hydroxyl value of 100 to 295 mg KOH/g. The polyol (b) is a multi-functional aliphatic or alicyclic polyol having 3 to 8 functional groups and has a hydroxyl value of 160 to 700 mg KOH/g. The weight of the oxyethylene groups included in the polyol component (A) is not more than 10% by weight in 100% by weight of the polyol component (A).
    • 本发明的目的在于提供一种用于切割的刚性聚氨酯树脂,其具有高的耐热性,无焦化和由于吸收空气中的水分而导致的膨胀减少。 用于切割本发明的硬质聚氨酯树脂形成组合物(P)包括:多元醇组分(A); 异氰酸酯组分(B); 无机填料(C); 和脱水剂(D)。 多元醇组分(A)包括:45至99重量%的多酚(j)烯化氧加合物(a),具有k个官能团的多酚(j),其中k为2或3的整数; 和1〜55重量%的多元醇(b)。 多酚(j)烯化氧加合物(a)含有至多不超过39重量%的多酚(j)烯化氧加合物(ak),至多k摩尔烯化氧,基于100重量% 多酚(j)烯化氧加合物(a),羟基值为100〜295mgKOH / g。 多元醇(b)是具有3〜8个官能团并且羟基值为160〜700mgKOH / g的多官能脂肪族或脂环族多元醇。 包含在多元醇组分(A)中的氧乙烯基的重量在多元醇组分(A)的100重量%中不超过10重量%。
