Effects of protective colloid on the melamine formaldehyde resin micro - encapsulation 保護膠體對三聚氰胺甲醛樹脂微膠囊成囊性影響的研究
Influences of content of soft monomer and hard monomer , emulsifiers , initiators , self - crosslinkable monomer and protective colloid on the properties of emulsion are studied 研究軟硬單體含量、乳化劑、引發(fā)劑、自交聯單體、保護膠體等對聚合物乳液性能的影響。
Self - crosslinkable latex at room temperature with high elasticity is prepared when n - hydroxymethyl acrylamide is used as self - crosslinkable monomer , and poly solidum maleate is applied as protective colloid , and pre - emulsified and semi - continuous seeded emulsion polymerization is adopted 采用n -羥甲基丙烯酯胺為自交聯單體,聚馬來酸鈉為保護膠體,采用預乳化半連續(xù)種子乳液聚合工藝,制備出高彈性室溫自交聯乳液。
Results show that self - crosslinkable latex at room temperature with high elasticity can be prepared when amount of butyl acrylate is 60 % , and amount of methyl methacrylate is 40 % , and mass ratio of nonionic emulsifier to anionic emulsifer is 3 : 1 , and amount of initiator is 0 . 6 % , and amount of self - crosslinkable monomer and protective colloid is 2 % and 0 . 4 % respectively 研究結果表明:當丙烯酸丁酯的質量為60 % ,甲基丙烯酸甲酯的質量為40 % ,非離子乳化劑和陰離子乳化劑的質量配比為3 : 1 ,引發(fā)劑的質量為0 . 6 % ,自交聯單體的質量為2 % ,保護膠體的質量為0 . 4 %時,可以制備出高彈性自交聯乳液。
