Abstract
The invention provides slow-rebound high-damping flexible polyurethane foam and a preparation method thereof, belonging to the technical field of foaming. The polyurethane foam is prepared from a polyether polyol composite material and an isocyanate composite material according to the mass ratio of 100: 35-65, and performing mixed foaming reaction to obtain the product; the polyether polyol composition material comprises the following components in parts by mass: 5-95 parts of polyether polyol, 5-95 parts of hyperbranched polyester polyol, 0.1-5 parts of foaming agent and 1-8 parts of foaming auxiliary agent. The invention also provides a preparation method of the slow-rebound high-damping flexible polyurethane foam. The slow-rebound high-damping polyurethane foam prepared by the invention has excellent mechanical property, slow rebound resilience and high damping property, can meet the higher performance requirement on shoe pad, protective tool and equipment protection in the existing market, and has wide market prospect.
Description
Technical Field
The invention belongs to the technical field of foaming, and particularly relates to slow-rebound high-damping flexible polyurethane foam and a preparation method thereof.
Background
The damping material is a typical functional material, and when vibration and impact are generated, the damping material can convert mechanical energy into heat energy so as to achieve the effect of reducing vibration and impact. The Polyurethane (PU) slow-rebound damping foam has the functions of light weight, slow rebound, good damping performance, sound insulation, energy absorption, shock resistance and impact resistance, and is widely applied to the protection of protective equipment and components such as insoles, gloves, knee pads and the like. The slow rebound high damping polyurethane foam is one of the polyurethane soft foams and is more and more in the visual field of people. However, the prior art still needs to be further improved for improving the damping factor of the material.
Disclosure of Invention
The invention aims to solve the problem of poor damping performance of the existing polyurethane foam, and provides slow-rebound high-damping flexible polyurethane foam and a preparation method thereof.
In order to solve the defects of the prior art, the invention adopts the following technical scheme:
the invention firstly provides slow-rebound high-damping flexible polyurethane foam, which is prepared from polyether polyol composite material and isocyanate composite material in a mass ratio of 100: 35-65, and performing mixed foaming reaction to obtain the product;
the polyether polyol composition material comprises the following components in parts by mass: polyether polyol5-95 parts of polyol, 5-95 parts of hyperbranched polyether polyol, 5-95 parts of hyperbranched polyester polyol, 0.1-5 parts of foaming agent and 1-8 parts of foaming auxiliary agent; the foaming density of the polyurethane foam is 0.25-0.85 g/cm3The damping loss tangent value is 0.5-1.2, and the glass transition temperature is 15-40 ℃.
Further, the hydroxyl value of the polyether polyol is 30-190 mgKOH/g, the viscosity is 100-1200 mpa.s, the molecular weight is 300-3000, and the water content is less than or equal to 0.15%.
