Abstract
The invention relates to a surface modifier formula for significantly reducing calcium carbonate oil absorption value. According to the formula, three surface modifiers of polyethylene glycol, triethanolamine and amino silicone oil are compounded; then, the composite surface modifier is heated to 50-95 DEG C and is added into a continuous powder surface modification machine according to a certain proportion of the weight of the calcium carbonate powder so as to carry out surface modification on calcium carbonate. DBP absorption value of the heavy calcium carbonate powder with its average granularity (D50) 5-10 microns after modified by the surface modifier formula can be reduced from 0.26ml/g-0.30ml/g before the modification to 0.13ml/g-0.17ml/g.
Description
1. technical field
The present invention relates to a kind of surface-treated agent prescription that can significantly reduce the lime carbonate oil-absorption(number), belong to powder surface modification and mineral material field.
2. background technology
Resin base artificial stone-like material is the novel organic/inorganic composite decorative building material that is composited by unsaturated polyester resin or epoxy resin and heavy calcium carbonate powder, has characteristics such as attractive in appearance, practical, safety, environmental protection, is kind with fastest developing speed among the artificial stone-like material.Water-ground limestone is the topmost filler of resin base artificial stone-like material, generally accounts for more than 75% of artificial stone-like material's quality, and loading level is big more, and resin demand is few more, and production cost is low more, also environmental protection more.Therefore, the loading level that increases water-ground limestone as far as possible is one of major technique developing direction of resin base rostone.
On the one hand because the inorganic nature of heavy calcium carbonate powder; Poor with the consistency of organic resin, for the bonding force of the consistency that improves itself and organic resin and enhancing and organic resin with the quality index of guaranteeing matrix material, satisfy corresponding country or industry standard must be carried out surface-treated to it; On the other hand, in order to increase the loading level of heavy calcium carbonate powder, also will be when improving itself and organic resin consistency big as far as possible its oil-absorption(number) of reduction.But existing calcium carbonate surface modifying prescription is mainly considered is the consistency that improves itself and organic resin.
The present invention is directed to the deficiency of existing heavy calcium carbonate powder surface-treated prescription, proposes a kind of surface-treated prescription that can take into account raising heavy calcium carbonate powder and unsaturated polyester resin or epoxy resin compatibility property simultaneously and significantly reduce its oil-absorption(number).Make the unsaturated polyester resin based composites can not only significantly increase the loading level of water-ground limestone, and the mechanical property of material and other performances do not descend.
3. summary of the invention
Calcium carbonate surface modifying prescription of the present invention (kind, usage, consumption) is as follows:
(1) surface-modifying agent kind: polyoxyethylene glycol (molecular weight 200～3000), trolamine and amido silicon oil;
(2) usage: 1. (1) described three kinds of surface-modifying agents are carried out compoundly, compound (quality) is than for polyoxyethylene glycol: trolamine: amido silicon oil=0～50: 0～55: 0～50; 2. compound surface-treating agent is heated to 50～95 ℃, in the certain proportion adding continuous powdery surface-treated machine by the calcium carbonate powder quality lime carbonate is carried out surface-treated.
(3) the compound surface-treating agent consumption is 0.2%～2.0% of a lime carbonate quality, specifically according to the product fineness of lime carbonate or specific surface area size and decide.
With the heavy calcium carbonate powder of mean particle size (D50) 5～10 μ m after the surface-treated agent prescription of the present invention modification, can be reduced to 0.13ml/g～0.17ml/g by the 0.26ml/g～0.30ml/g before the modification to the absorption value of DBP (Witcizer 300).
