Abstract
The invention provides a production method of a high-intensity and high-alkali resistance fiberglass mesh, which is widely used in the building fields of the inner wall and outer wall of a building, the slope protection of a highway and the like. The method comprises the following steps of: preparing a soft and non-stick emulsion coating layer by means of the polymerization of core-shell emulsion, inducing an organic silicone coupling reagent in the process of polymerization, internally adding a cross-linking agent, and externally adding a curing agent, so that the binding force between the coating layer and the fiberglass mesh can be improved, and the positioning effect can be increased. Due to the cross-linking performance and hydrolytic resistance of the organic silicone, the alkali resistance of the coating layer can be improved. The problems that the existing fiberglass mesh is not high in 'hot glue cold shortness' intensity and alkali resistance retention rate due to the fact that the acrylate emulsion used by the fiberglass mesh is taken as the coating layer can be solved. According to the production method, not only can the alkali resistance retention rate of the fiberglass mesh be improved, but also the tensile strength of the fiberglass mesh can be increased.
Description
Technical field:
The present invention relates to the high alkali-proof glass fiber mesh manufacture method of a kind of high strength, as a kind of reinforcing material, because to have tensile strength high, high temperature resistant, corrosion-resistant, be widely used in the building inner, external wall, and the building field such as highway bank protection,
Background technology:
Because the used acrylic acid ester emulsion of fiberglass gridding cloth exists " hot sticky cold crisp " intensity and the not high characteristics of Alkali resistivity as coating, restricting fiberglass gridding cloth to the outlet of more American-European developed countries always, domestic many institutes make a lot of modifications in this regard, but owing to all having some shortcomings, cost performance is low, all is restricted in production application.
Summary of the invention:
It is by core-shell emulsion polymerization that the present invention will deal with problems, prepared emulsion coating softness and adhesion, and in polymerization process, introduced organo-silicon coupling agent, in add crosslinking agent, add curing agent, improve the adhesion between coating and the fiberglass gridding cloth, increase locating effect.And utilize organosilicon crosslinked and water resistance, improve the coating alkaline resistance properties.Namely improve the alkali resistant retention rate of fiberglass gridding cloth, increased again fiberglass gridding cloth tensile strength simultaneously.
The specific embodiment:
1. respectively with nuclear monomer and shell monomer and corresponding water, emulsifying agent at room temperature fully mixes, emulsification 2 hours.Pre-emulsion and shell pre-emulsion both must have been examined.
2. agitator is being housed, in the four-hole reaction flask of thermometer and reflux condenser, constant pressure funnel, add part and examine pre-emulsion and part initiator solution, slowly be warming up to 82 ℃ under stirring without after refluxing, drip simultaneously residual nucleus pre-emulsion and initiator solution, the control rate of addition is moreed than after 1/3 at pre-emulsion, and beginning drips simultaneously A-171 (organo-silicon coupling agent).Shell pre-emulsion, dropping temperature remain on 84 ± 2 ℃, and time for adding 4-45 hour, initator lagged behind and adds half an hour.Be incubated 1.5 hours, pH value is transferred in cooling, adds the nanometer SiO2 of formula ratio, and adds curing agent.
3. by core-shell emulsion polymerization, prepared emulsion coating softness and adhesion, and in polymerization process, introduced organo-silicon coupling agent, in add crosslinking agent, add curing agent, improve the adhesion between coating and the fiberglass gridding cloth, increase locating effect.And utilize organosilicon crosslinked and water resistance, improve the coating alkaline resistance properties.Greatly improved the alkali resistant retention rate of fiberglass gridding cloth.
