Abstract

The invention discloses a multifunctional acrylic ester emulsion, which is prepared from deionized water, an initiator, an emulsifier, acrylic acid alkyl ester of C4 to C12, alkyl methacrylate of C4-C12, an aryl unsaturated monomer, an unsaturated monomer of C3 to C4, an acrylamide functional monomer, a silane coupler, and other components which are subjected to mechanical stirring to disperse olefin unsaturated monomers into water, and carry out free radical polymerization under the action of the initiator to obtain the emulsion. The emulsion in thermal insulation mortar has the functions of reinforcing tenacity and strength, remarkably improves the bonding strength of the mortar, increases the compressive strength/rupture strength ratio of hardened mortar, and brings about the stable quality of walling materials, improves construction efficiency and reduces mortar contraction. The emulsion which is applied to polymer cement waterproof paint has good water proofing function with great tensile strength and high extension coefficient.

Description

technical field [0001] The invention relates to an emulsion, in particular a multifunctional acrylate emulsion, which can be added to thermal insulation mortar to improve the bonding strength between the thermal insulation mortar and the base material and the toughness, water resistance, and weather resistance of the thermal insulation mortar . The emulsion is used in polymer cement waterproof coatings, and a good balance between strength and elongation can be obtained, so that the coatings have good waterproof performance. Background technique [0002] Our country has promulgated many relevant regulations, implementing the building energy-saving 65% standard, and requiring all urban buildings to adopt external wall insulation technology. Order No. 143 of the Ministry of Construction "Regulations on the Administration of Energy Conservation of Civil Buildings" Encourage the development of new energy-saving wall and roof insulation, heat insulation technology and materials f...
