摘要
以质量分数50%的聚硅氧烷(DC-3074)、20%聚氨酯(DH317)和30%三丙二醇二丙烯酸酯(TPGDA)为原料,经室温下冷混制得改性聚硅氧烷树脂,再以质量分数14%的氨基硅烷(HD-602)为固化剂,并加入适量颜料及助剂而制得改性聚硅氧烷彩色涂膜.该涂料具有优良的耐候性能(3 000h失光率≤15%),预计可用作钢结构重防腐涂料.
A modified polysiloxane resin paints at room temperature was prepared by using 50%( mass fraction)of polysiloxane (DC 3074),20% polyurethane(DH317)and 30% tripropylene glycol dia-crylate (TPGDA)as starting materials,and adding the total mass of 14% amino silane (HD 602)as curing agent and the amount of pigment and additives,we obtained a modified polysiloxane resin color paints.The coating,which has excellent resistance to weathering,is expected to be applicable for paint for steel structure corrosion protection.
