Abstract
The invention discloses a foaming polyurethane material used for a sound insulating pad. The foaming polyurethane material comprises the following components of, by weight, 100-120 parts of polyether polyol, 5-8 parts of isocyanate, 1.3-2.5 parts of diethyl ethylphosphonate, 10-20 parts of water, 0.5-1.5 parts of a polysiloxane-polyoxyalkylene block copolymer, 0.05-1.2 parts of a cross-linking agent and 5-30 parts of cyanuramide. The prepared foaming polyurethane material used for the sound insulating pad has the advantages of good sound insulating effect and good flame retardant property by using polypropylene oxide glycol and polyoxypropylene triol as raw materials, cyanuramide as a fire retardant agent and water as a foaming agent.
Description
Technical field
The present invention relates to the urethane applied technical field, specifically a kind of sound insulating pad blown polyurethane materials.
Background technology
Polyurethane rigid foam plastic is widely used in the aspects such as building, communications and transportation and does lagging material and structured material.Gradually reinforcement along with energy-saving and emission-reduction consciousness, people more and more note the impact of environment at one's side, especially noise, polyurethane material is the material with vesicular structure of favorable elasticity, effect with good sound absorption, sound insulation and damping shock-absorbing noise-reducing, be a kind of desirable sound-proof material, that is that all right is ripe in the at present applied research of this respect.
Summary of the invention
The object of the present invention is to provide a kind of sound insulating pad blown polyurethane materials.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of sound insulating pad blown polyurethane materials is characterized in that each component and weight part are as follows:
Polyether glycol 100-120 part
Isocyanic ester 5-8 part
Ethyl phosphonic acid diethyl ester 1.3-2.5 part
Water 10-20 part
Polysiloxane-olefin oxide segmented copolymer 0.5-1.5 part
Linking agent 0.05-1.2 part
Trimeric cyanamide 5-30 part
Described polyether glycol is the mixture of polyoxypropyleneglycol and polyoxytrimethylene triol, and the weight part ratio of polyoxypropyleneglycol and polyoxytrimethylene triol is 1:3.
Described linking agent is diethanolamine or glycerine.
Beneficial effect of the present invention: the present invention is take polyoxypropyleneglycol and polyoxytrimethylene triol as raw material, and trimeric cyanamide is fire retardant, and water is whipping agent, and it is good that the sound insulating pad of preparation has a soundproof effect with blown polyurethane materials, the advantage that flame retardant properties is good.
