Abstract
The present invention provides a prefabricating method for concrete products and a mould thereof. The prefabricating method comprises the steps that cement, sand and stone materials, a coloring agent and reinforcement materials are mixed and stirred with water according to the design requirement, and finished products can be obtained through casting, vibration, maintenance, demoulding and surface strengthening or beautification processing finally. The mould is an elastic mould produced by that a prepolymer, solidification materials and an adjusting agent are mixed by weight proportion of (35 to 50): (46 to 68): (2 to 4) according to the design requirement to shape and dimension and through stirring, casting and solidifying at normal temperature. The prefabricating method can be used for prefabricating and designing the concrete products with complex shape and surface and a plurality of designs and varieties and other concrete products, such as plate tiles for decoration, vista sculptures with deep relieves and deep hole grooves, etc.
Description
The present invention relates to a kind of mould that is used for concrete product.
Known concrete product mould; the general rigid die that adopts; mould as wooden model, metal pattern, plaster mold or other rigid material are made injects mould after vibrate or compression moulding with concrete casting, and its weak point is that the Mold Making expense is more expensive; can only disposablely use as plaster mold; goods body and size are also restricted, and it is comparatively simple to be only applicable to make body and surface, the concrete product that size is less; be not suitable for design body and surface complexity, the concrete product that designs and varieties are many.French Patent (FRP) FR2575696A discloses a kind of concrete product elastic mould, it is made by polystyrene foam plastics, can only a kind of concrete product elastic mould be disclosed disposable use German patent DE 2846391A, it is by metal and rubber combined making, and the effect of rubber layer is confined to vibration damping and wear-resisting.These two kinds of mould moldings need adopt high temperature, high-pressure molding, complex process.
The object of the present invention is to provide a kind of cheap, be suitable for designing body and the surface is complicated, designs and varieties are more, and can make the concrete product mould of moulding at normal temperatures and pressures.
Technical solution of the present invention is as follows:
This mould is the geomery according to designing requirement, is mixed in proportion by plastic material base polyurethane prepolymer for use as, solidifying substance and adjustment agent, mixes the elastic mould that cast and curing form at normal temperatures through disturbing.
Base polyurethane prepolymer for use as comprises polyethers or polyester material, and solidifying substance is chemical material such as the coal tar pitch that contains amido, and the adjustment agent is a banana oil, cyclohexanone, dimethylbenzene etc.
Solidifying substance can with prepolymer reaction, and make its curing.Adjust agent for improving the additive of the every physicochemical property before and after the mould molding.
The part by weight of mould material therefor is: performed polymer: solidifying substance: adjust agent=(35-50): (46-68): (2-4), this mould has elasticity, can independently use, also can with the use that coincides of rigidity external mold or bed die.The mould the key technical indexes is tensile strength 〉=1.5MPa, hardness (Shao Shi) 〉=40 ° A percentage elongation 〉=200%, hardenite proportion 1.10-1.30.
The present invention has following accompanying drawing:
Fig. 1 is colorful concrete unit marking board,
Fig. 2 is a sign board mould vertical view,
Fig. 3 is a unit marking board A-A profile
Fig. 4 locates profile for mould A '-A '.
This mould can be at the normal temperature and pressure conditions compacted under, and manufacture craft is simple, but Reusability is with low cost, Can be used for designing body and surface complexity, the batch production of the concrete product that designs and varieties are more.
Embodiment: unit marking board mould
Performed polymer uses polyisocyanates, curing agent uses coal tar pitch, adjust agent and use banana oil, its part by weight is: 35: 61: 4, stir at normal temperatures, cast, curing, make the mould of the pattern that requires, be mainly the unit marking board that letter constitutes as shown in Figure 1, Fig. 2 is mould, Fig. 1 is opposite with Fig. 2 pattern, and depression is opposite with projection.
Claims (2)
1. concrete product mould, this mould has elasticity, it is characterized in that: it is the shape according to designing requirement, size is by the plastic material base polyurethane prepolymer for use as, the solidifying substance of amino-contained class material and adjustment agent be (30-50) by weight proportion: (46-68): (2-4) mix, at normal temperatures through stirring the elastic mould that cast and curing form.
2. a kind of concrete product mould according to claim 1 is characterized in that: performed polymer is polyethers or polyester material, and above-mentioned solidifying substance is as coal tar pitch, and the adjustment agent is banana oil, cyclohexanone, dimethylbenzene.
