Abstract
The invention discloses resin concrete, which is prepared from the following raw materials in percentage by mass: 10-40% of resin cementing component, 30-60% of aggregate and 5-40% of filler. By reducing the particle size of the aggregate, improving the fineness of the material components and reducing the internal defects (pores and microcracks) of the materials, the cohesive force of the concrete is enhanced, and superhigh strength and high durability are achieved. The cube compressive strength can be more than or equal to 150MPa, and the resin concrete has high strength.
Description
Technical field
The invention belongs to the technical field of material of construction, be specifically related to a kind of resin concrete of higher-strength.
Background technology
Resin concrete adds that appropriate solidifying agent, toughner, thinner and filler are as tackiness agent using synthetic resins (PolymerResin), with sand, stone for aggregate, through mixing, shaping, solidification a kind of matrix material.Because it has good resistant to corrosion, wear-resisting, water-fast and freezing tolerance and mechanical property, the shortcomings such as tensile strength is low, tensile strain is little, splitting resistance is poor although resin concrete compensate for portland cement concrete, brittle rupture.But for some ultra high strength concretes, its ultimate compression strength is up to more than 200MPa, and even up to 800MPa, resin concrete still exists the situation of insufficient strength, cannot be applied in the field of some high requests.
Summary of the invention
The object of the invention is to the resin base concrete preparing a kind of higher-strength, to meet the application in some high performance requirements fields.
The object of the present invention is achieved like this, the described strong resin concrete of a kind of superelevation, and the weight fraction (%) of each component is:
Plastic bonding component 10-40.0
Aggregate 30-60
Filler 5-40.
Above-mentioned each constituent mass mark sum is 100%.
Described plastic bonding component comprise unsaturated polyester, epoxy resin one or both.Above-mentioned unsaturated polyester is one or more in vinyl ester resins, adjacent benzene-type unsaturated polyester, metaphenylene unsaturated polyester, bisphenol A-type unsaturated polyester.Above-mentioned epoxy resin is one or more in glycidyl ether type epoxy resin, glycidyl ester epoxy resin, glycidyl amine epoxy resin, linear aliphatic based epoxy resin, alicyclic based epoxy resin; Plastic bonding component of the present invention effect is in the present invention that each component bonding is become the lower entirety of a voidage, its mechanism is that plastic bonding component makes grouping divide formation an aggregate as binding agent, increase the bonding force of resin and inorganic components simultaneously, increase resin to the wettability of inorganic component, effectively eliminate air and reduce voidage.
Upper plastic bonding component also comprises one or more in coupling agent, thinner, softening agent, defoamer, solidifying agent, described coupling agent, thinner, softening agent, defoamer, solidifying agent adopt coupling agent and solidifying agent component or coupling agent, thinner and curing agent component or coupling agent, defoamer and curing agent component etc. respectively, preferred coupling agent, defoamer and curing agent component.Described aggregate is quartz sand, grouan or marble; Aggregate size is at 0.1-2mm.Filler is one or more in calcium carbonate, silicon powder, barium sulfate, calcium sulfate, potter's clay, aluminum oxide, aluminium hydroxide.
Preparation method of the present invention is: by proportioning by aggregate through cleaning, dry, aggregate and filler drying and vinyl ester resin, coupling agent, promotor and solidifying agent agent enter stirred pot after measuring respectively, after stirring, put into model, after vibrating compacting is deposited, enter drying room after demoulding, after baking, namely form resin concrete goods.
Beneficial effect of the present invention is: the aggregate not more than 2mm in the component of resin concrete, and the textural defect that coarse aggregate can be avoided to cause affects the intensity of resin; Add defoamer and just effectively can get rid of air in whipping process, increase the degree of compactness of resin, improve the ultimate compression strength of resin; Coupling agent effectively can increase the bonding force of mineral aggregate and filler, and greatly improve ultimate compression strength and the flexural strength of resin, the resin concrete intensity that the present invention obtains is high, density is little.
