摘要
全水发泡体系本身具备一定的环保及成本优势,但阻燃性能、绝热性能、尺寸稳定性、粘接性能均比较差。通过优化配方各组分,筛选了特殊的多元醇、添加剂及催化剂,在保证阻燃等级达到B2的前提下,制备了各项性能均符合行业要求的高阻燃全水发泡型聚氨酯材料。
The replacement technology of foaming agent for polyurethane insulation board was briefly reviewed. The water foaming agent system had the advantage in environmental protection and low cost, but also had many shortcomings, such as flame-retardant property, heat-insulating property, dimensional stability and adhesive proper- ty. By optimizing the formula components, special polyol, additive and catalyzer were selected. The high flame re- tardant and water-blown polyurethane material whose various performance was met the requirements in the field was prepared, the flame retardant grade reached up to B2.
