Abstract

The invention discloses a method for preparing a modified hydroxyl ester polymer emulsion. Required raw materials comprise the following components in parts by mass: 1.0-4.2 parts of a hydrophilic small monomer for emulsification, 1.7-4.5 parts of a hydrophobic small monomer for emulsification, 18-51 parts of a hydroxyl small monomer, 0.05-0.26 part of an emulsion initiator, 2.2-5.4 parts of an initiator a, 3.5-6.6 parts of an initiator b, 380-450 parts of an ester small monomer, 6.2-9.3 parts of a crosslinking agent, 0.06-0.28 part of a chain transfer agent, 0.5-1.0 part of graphene oxide, 15-40 parts of polyether, 5-10 parts of a neutralizer, 5-10 parts of a pH regulator, 2.0-6.5 parts of an emulsifier promoter, 0.4-1.3 parts of a liquid film enhancer and the balance of water, wherein the total parts by mass are 1000, and the solid content is 50%. The waterproof coating disclosed by the invention is suitable for cement mixing; due to a large number of hydroxyl groups, calcium ions can be stably complexed, calcium ion hydrolysis can be effectively inhibited, the cement strength can be increased, and the waterproof effect can be improved; due to hydrogen bonds in molecules of the hydroxyl groups, the internal binding force of the polymer can be improved, and the adhesion of the polymer with a matrix can be improved through a good hydrophilic effect; due to addition of the graphene oxide, the tensile strength of a polymer emulsion in film formation can be remarkably improved; and the water resistance can be also improved to a certain extent.

Description

technical field [0001] The invention belongs to the technical field of building waterproof materials, in particular to a preparation method of a modified hydroxy ester-based polymer emulsion. Background technique [0002] Waterproof coatings are widely used in building waterproof materials due to their simple construction, high film strength and good waterproof effect. Hydroxyl ester-based polymer waterproof coatings are mainly composed of hydroxyl small monomers and ester-based small monomers. A waterproof coating with excellent performance can be applied to a wide range of waterproof markets. [0003] The waterproof market can be divided into three parts: tooling, home decoration, and leak repair. Tooling waterproofing refers to the waterproof design and construction applied to large-scale construction projects, and the amount is relatively large; home improvement waterproofing refers to small-scale waterproofing construction for commercial housing, private buildings and o...
