Abstract
A string-like sealing material characterized in that (1) the string-like sealing material is a string-like body (a) obtained by forming a thermosetting resin composition comprising a synthetic resin and a heat-curing agent or a string-like composite structure (b) obtained by arranging a dimension-stabilizing aid along the lengthwise direction of the string-like body (a), (2) the elongation percentage thereof is within 10% as measured by applying a load to become stress of 5 N/cm2 per unit sectional area at 23° C. for 5 minutes to the string-like sealing material in the lengthwise direction thereof, and (3) the string-like body (a) has high shape-retaining ability at normal temperature (5 to 35° C.), but exhibits good melt flowability upon its heat curing.
Claims11
A string-like composite structure sealing material (b), comprising a dimension-stabilizing aid other than a metal wire arranged along the lengthwise direction of a string-like body (a), wherein
- (1) the string-like body is obtained by forming a thermosetting resin composition comprising a synthetic resin and a heat-curing agent,
- (2) the elongation percentage thereof is within 10% as measured by applying a load to become stress of 5 N/cm2 per unit sectional area at 23° C. for 5 minutes to the string-like composite structure sealing material in the lengthwise direction thereof, and
- (3) the string-like body (a) has shape-retaining ability at normal temperature (5 to 35° C.), but melt-flows upon its heat curing,
- wherein the string-like composite structure sealing material (b) is selected from the group consisting of a string-like composite structure (b1) which comprises the dimension-stabilizing aid composed of a linear material and a layer of the thermosetting resin composition formed around the dimension-stabilizing aid, and a string-like composite structure (b2) which comprises a string-like body formed by melt extrusion of the thermosetting resin composition and the dimension-stabilizing aid composed of a linear material embedded within the surface of the string-like body, and
- wherein the thermosetting resin composition further comprises a filler in a proportion of 0.1 to 50 parts by weight per 100 parts by weight of the synthetic resin.
A string-like composite structure sealing material (b), comprising a dimension-stabilizing aid other than a metal wire arranged along the lengthwise direction of a string-like body (a), wherein
- (1) the string-like body is obtained by forming a thermosetting resin composition comprising a synthetic resin and a heat-curing agent,
- (2) the elongation percentage thereof is within 10% as measured by applying a load to become stress of 5 N/cm2 per unit sectional area at 23° C. for 5 minutes to the string-like composite structure sealing material in the lengthwise direction thereof, and
- (3) the string-like body (a) has shape-retaining ability at normal temperature (5 to 35° C.), but melt-flows upon its heat curing,
- wherein the string-like composite structure sealing material (b) is selected from the group consisting of a string-like composite structure (b1) which comprises the dimension-stabilizing aid composed of a linear material and a layer of the thermosetting resin composition formed around the dimension-stabilizing aid, and a string-like composite structure (b2) which comprises a string-like body formed by melt extrusion of the thermosetting resin composition and the dimension-stabilizing aid composed of a linear material embedded within the surface of the string-like body, and
- wherein the thermosetting resin composition comprises, as the synthetic resin, a thermosetting resin and a thermoplastic resin at a weight ratio of 0.5:99.5 to 95:5, and the heat-curing agent in a proportion of 0.01 to 15 parts by weight per 100 parts by weight of the synthetic resin.
