Embodiment 2

[0077] This embodiment is basically the same as Embodiment 1, the difference is:

[0078] S2 preparation system solution

[0079] In the 300kg stainless steel reactor after cleaning and vacuumizing, add 30kg deionized water, 0.05kg electrolyte, 0.01kg chelating agent, 0.01kg pH buffering agent, stir and disperse and dissolve evenly to obtain a system solution, and the system solution is heated to 80-85°C.

[0080] Preparation of S3 emulsion

[0081] To the system liquid, add 20kg of water phase dropwise, 13kg of oil dropwise, and 5kg of initiator dropwise, and keep warm for 1-2 hours.

[0082] Add the remaining 36.7kg of water phase addition phase, 111.4kg of oil phase addition phase, and 45.7kg of initiator addition phase to the reaction system dropwise, and drop reaction for 3-5 hours, and gradually control the reaction temperature at 85-95°C , after the dropwise addition is completed, keep warm for 2-3 hours, take samples every 0.5-1 hour, and test the solid content. Whe...

Embodiment 3

[0084] This embodiment is basically the same as Embodiment 1, the difference is:

Abstract

The invention belongs to the technical field of emulsion polymerization in high polymer materials, and relates to carboxylic butadiene-styrene latex for carpets. The latex is prepared from the following raw materials: a water phase dropwise adding phase, an initiator dropwise adding phase, an oil phase dropwise adding phase and system liquid. The water phase dropwise adding phase comprises deionized water, a stabilizer, a dispersing agent and a cross-linking monomer. The initiator dropwise adding phase comprises deionized water and an initiator. The oil phase dropwise adding phase comprises styrene, a functional monomer, a co-stabilizer, a molecular weight regulator and butadiene. The functional monomer comprises organic silicon polyether modified unsaturated carboxylic acid and lipid thereof. The invention further discloses a preparation method of the carboxylic butadiene-styrene latex for the carpet. The prepared carboxylic butadiene-styrene latex is narrow in particle size distribution, the bonding strength between carpet fibers and backing chemical fiber grids is improved, and the peel strength, the water resistance, the heat resistance, the wear resistance, the softness, the hardness and the like of the carpet are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of emulsion polymerization in polymer materials, and relates to a back-coating adhesive for tufted carpets, cut-pile carpets and printed carpets, in particular to a carboxylated styrene-butadiene latex for carpets and a preparation method thereof . Background technique [0002] Carpets are made of natural fibers such as cotton, hemp, and wool, or chemical synthetic fibers such as polypropylene, acrylic, polyester, and nylon. They are braided, velvet, or spun by manual or mechanical processes. They are used in hotels, hotels, residences, gymnasiums, and exhibitions. It is a kind of arts and crafts for anti-skid, noise reduction, heat insulation, shock absorption and decoration of halls, vehicles, aircrafts, ships and other grounds. According to different materials, carpets can be divided into chenille carpets, blended carpets, silk carpets, chemical fiber carpets, plastic carpets and other types. And other ...
