Abstract
The invention discloses a composite dispersant for a resin anchoring agent. The composite dispersant is obtained by mixing a chelating dispersant, a heavy metal chelator and a hyperdispersant with a mass ratio of 1 : 1 : 2 into a mixed liquid suspension, wherein the chelating dispersant is maleic anhydride-acrylic acid copolymer, the heavy metal chelator is dithiocarbamate derivatives, and the hyperdispersant is ethoxy modified trisiloxane. When anchoring agent clay is produced, the composite dispersant with an amount of 2-6 % of that of the resin, together with the resin, is poured into a clay premix tank for stirring. According to the invention, the metal chelator can effectively chelate metal ions such as iron ion, aluminium ion, etc. in stone powder filling materials and prevent their participation in the anchor reaction; and the dispersant can rapidly and fully moisten filling material particles, reduce interfacial tension, and prevent settlement and coacervation of solid particles. By using the composite dispersant, curing parameters of the resin anchoring agent do not obviously drift, thereby greatly reducing probability of false coacervation phenomena, ensuring quality of the resin anchoring agent, increasing adding amount of the filling materials by more 10 % based on original amount under a same quality, and effectively reducing cost.
Description
Technical field
The present invention relates to a kind of resin anchoring agent composite dispersing agent, be specifically related to unsaturated polyester resin Anchor Agent field.
Background technology
Unsaturated polyester resin Anchor Agent is widely used in rib, the roof timbering in colliery, the roof timbering in tunnel, and the aspects such as the seismic hardening of pit shaft installation and buildings, are important component parts of supporting industry.
The validity period of resin anchoring agent is three months, but is immediately used by user after dispatching from the factory and necessarily, often will deposit considerable time.In this process, the metallic impurity that contain in the limitation of the promotion curing system of the slow consumption of the stopper in Anchor Agent resin components and employing and filler cause the curing process parameter of gel time, set time, exothermic peak of Anchor Agent etc. to change, we are called curing process parameter " drift ", with the difference of condition of storage and the length of time, the degree of drift is different.The metallic impurity at high proportion that contain in because of stone powder filler in the time of summer of especially severe, cause may also there will be false set in Anchor Agent production process, make the actual gel time of Anchor Agent fast more a lot of than what design, and there is no thermal discharge, ultimate compression strength is very low, serious impact the quality of resin anchoring agent, in addition, along with resin anchoring agent is significantly promoted the use of, demand increases day by day, add the useful competition of manufacturer, market is also day by day harsh to the requirement of production cost.Undoubtedly, the addition that increases filler is the most effectively and directly to fall cost method, but all will meet under industry standard requirement at all technical that guarantees quality product, suffers from a loss what to do.
Summary of the invention
For solve above-mentioned resin anchoring agent curing process parameter " drift " and cannot increase the problem that amount of filler reduces production costs, the invention provides a kind of resin anchoring agent composite dispersing agent.
The present invention adopts following technical scheme to achieve these goals:
Resin anchoring agent composite dispersing agent, by chelated dispersants and heavy metal chelant and hyper-dispersant in mass ratio the ratio of 1:1:1.8-2.2 be mixed with mix suspending liquid and obtain.
Resin anchoring agent composite dispersing agent, by chelated dispersants and heavy metal chelant and hyper-dispersant in mass ratio the ratio of 1:1:2 be mixed with mix suspending liquid and obtain.
Described chelated dispersants is copolymer of maleic anhydride and acrylic acid; Described heavy metal chelant is dithiocarbamate salt derivative; Described hyper-dispersant is oxyethyl group modification trisiloxanes.
Described resin anchoring agent is poured in clay Preblend cabin and is stirred and produce Anchor Agent clay by the 2-6% of amount of resin with composite dispersing agent together with resin.
Beneficial effect of the present invention:
Metal ion in the effective chelating stone powder filler of metal chelator energy of the present invention is participated in anchoring reaction as iron ion, aluminum ion etc. prevent it, and dispersion agent can soak filler particles fast fully, and reduction interfacial tension, prevents sedimentation and the cohesion of solid particulate; In resin anchoring agent, use this composite dispersing agent after fixing parameter that obvious drift can not occur, greatly reduce the occurrence probability of false set, guarantee the quality of resin anchoring agent, and under identical quality, filler addition has improved more than 10% on original basis, effectively reduces cost.
Embodiment
Embodiment 1: resin anchoring agent composite dispersing agent, by chelated dispersants and heavy metal chelant and hyper-dispersant in mass ratio the ratio of 1:1:2 be mixed with mix suspending liquid and obtain.
Described chelated dispersants is copolymer of maleic anhydride and acrylic acid; Described heavy metal chelant is dithiocarbamate salt derivative; Described hyper-dispersant is oxyethyl group modification trisiloxanes.
In the time producing Anchor Agent clay, this composite dispersing agent is poured in clay Preblend cabin and is stirred by the 2-6% of amount of resin together with resin.
The effect comparison of following table 1 for adding composite dispersing agent and not adding composite dispersing agent:
Table 1:
