Isocyanate triglyceride modified water-based polyester performance study
Summary:
Introducing isocyanic acid tricelyceride trisulphate (TGIC) modified water-based polyester resin, using isocyanate and epoxy-based open-loop reaction to generate ester bonds and hydroxyl and further react to obtain hexa-branched island structure polyester resin. Microstructure analysis of isocyanate triglyceride (TGIC) modified water-modified polyester resin was carried out by infrared spectroscopy, X-ray diffraction and gel chromatography, comparing isocyanate triglycerides, tributyl alcohol and trihydroxymethyl propane as branching groups for water-based polyester resin storage stability, T bending, The effects of heat resistance, water-resistant cooking performance and solvent-resistant properties were found that isocyanate trisulphate (TGIC) modified water-based polyester resin has better T-bending and heat resistance, and other properties include solvent-resistant wipe resistance, water-resistant cooking resistance and resistance to water-based polyester using other adipose branch monomers.

Research on the Preparation and Application of Multi-Cross-Cross hydroxypropyl acrylates emulsions
Abstract:
Is a monosome dominated by acrylates (BA) and methyl acrylates (MMA), Acrylic acid (AA), methyl acrylic hydroxyethylate (HEMA) and diacetone acrylamide (DAAM)/hexate diamide (ADH) self-interlinking system is a functional monolith, using a semi-continuous emulsion polymerization process to prepare wood with multi-cross-linked hydroxypropyl acrylates emulsion. The effects of HEMA, DAAM/ADH, AA dosing, and glass transition temperature (Tg) on emulsion and coating properties were explored. The results showed that when the hydroxyl content was 4%, DAAM and AA accounted for 2% and 1.5% of the total monomer, respectively, and the emulsion Tg was designed to be 20 degrees C, the preparation of hydroxypropyl acrylic emulsion was made of two-part wood varnish, the film hardness of up to 2H, adhesion 0 grade, excellent water resistance and good chemical resistance.

Application of drilling solid waste in non-cured rubber asphalt waterproof coatings
Abstract:
oil and gas field drilling process will produce a large amount of solid waste, these waste contains a large amount of crude oil And chemical additives, very difficult to deal with, in order to effectively solve this problem, rational use of resources, this study from the modified asphalt waterproof coating, through the treatment of drilling solid waste to replace part of the inorger filler, added to the non-cured rubber asphalt waterproof coating, To determine the change of coating performance, then explore the feasibility of drilling solid waste in non-cured rubber asphalt waterproof coating. The results show that the solid waste can completely replace inormeric fillers, can effectively improve the softening point and elongation of the coating, improve the low tenderness of the finished non-cured rubber asphalt waterproof coating, the low tenderness after thermal aging, reduce the viscosity of the coating makes it easier to construct, and can improve the extension, creep and self-healing of the coating. Due to excessive performance surplus, the formulation can be optimized to reduce the amount of styrene-butdene-styrene insert co-polymer (SBS) modifier, reducing production costs. The research introduces the solid waste of oil and gas field into the waterproof coating of non-cured rubber asphalt, solves the problem of the difficulty of treating the waste, and improves the performance of the waterproof coating of non-cured rubber asphalt.
