Study on Preparation and Performance of Silicate/Polyurethane-urea Composite Reinforcement Materials
The silicate/polyurethane-urea composite reinforcement materials were prepared with silicate and polymethylene polyphenyl polyisocyanate(PAPI)as main raw materials.The effects of the dosage of silicate,PAPI,trioctyl citrate and polyol POP45G on the properties of silicate/urethane-urea composites were studied,and the composite reinforcement material was characterized by infrared spectroscopy and thermal properties.The results showed that,with 82～86 parts of mixed silicate aqueous solution as the main component of A,with 65～67 parts of PAPI,8～10 parts of trioctyl citrate and 15～20 parts of POP45G as the main component of B,the amorphous polymer silicate/polyurethane-urea composite reinforcement material was prepared by mixing A and B.The material had excellent mechanical properties and flame retardant properties.The composite reinforcement material was green and environmentally friendly,and had good safety and cost performance.
