Abstract
The invention discloses a cool viscoelastic polyurethane foam material. The polyurethane foam material is made by one-step synthesis at normal temperature. A reaction system of the polyurethane foam material contains a polyol mixture, polyisocyanate and a supplementary agent with mass ratio of 100:30-60:30-10. The cool viscoelastic polyurethane foam material is of open cell type with good air permeability, thus avoiding stuffiness in use in summer; and has low temperature sensitivity, thus being capable of keeping soft in winter and being convenient for use.
Description
Technical field
The present invention relates to polyurethane material, be specifically related to a kind of cool type viscoelastic polyester form material.
Background technology
Visco-elasticity polyurethane foam material is called slow-recovery sponge again, be viscoelastic foam or the elastomerics of making by polyisocyantates composition and polyol blends and additive, the comprehensive physicals of this viscoelastic materials offer superior comprises amazing low compression set.
Visco-elasticity polyurethane foam material is mainly used to produce articles for use such as pillow, mattress, cushion, is widely used in people's life, leisure, work.This material is perception people's the bodily form and body weight fully, distortion is fit to people's body shape, and provide proper supporting power, it can make people's head, neck, spine, buttocks and knee no matter lie on the back in sleep or lie on one's side, neck waist space is all filled up and is subjected to flexibly supporting, pressure is distributed to each several part, is in relaxation state fully, does not have constriction.Especially cervical vertebra can keep the physiological status of nature, and no unsettled, nothing bending is subjected to effective protection; When health has left slow-recovery sponge, pressure is removed, pillow mattress can slowly reply the original form of its memory.
Improvement along with people's living standard, pillow, the mattress made by visco-elasticity polyurethane foam material have become the common daily necessities of people, bring benefit can for people's health, people wish the slow-recovery sponge mattress and the pillow that comprise summer at all seasons and can both use excellent performance winter.But at present visco-elasticity polyurethane foam material also exists some shortcomings: temperature sensitive property is big, to 5 ℃ just begin to become very hard, almost can't use in the room that does not have heating installation winter; Perforate is relatively poor, and ventilation property is bad, and the nice and cool property of tool is not suitable in particularly moist place use in summer.
