Description
Technical field
The present invention relates to the preparation method of a kind of composite light cement.
Background technology
Cement is one of three big stocks of building industry, have the title of " grain of building industry ", even novel
Today that construction material constantly occurs, cement remains topmost construction material.Cement is seldom used alone, and is more
Forming composite as a kind of colloid with other materials combination to use, most popular cement-base composite material is coagulation
Soil.Due to fracture toughness, the tension of concrete, bending strength all Shortcomings, so occurring in that fibre-reinforced cement based
Composite, this be a kind of by chopped fiber (steel fibre, carbon fiber and polymer fiber etc.) as gathering materials and concrete-agitating shape
The new composite become, the combination by chopped fiber with cement slurry forms Discontinuous Reinforcement effect, can be effectively improved coagulation
The toughness of soil and intensity.Additionally, also have a kind of polymer cement based composites to be widely studied, polymer is with emulsion form
Participate in the solidification process of cement, by the impact of hardening of cement process being changed the performance of cement.Polymer is reinforcing material,
It is again colloidal materials, cement is played toughness reinforcing, plasticising, filling perforation and the effect of solidification, the strong of concrete material can be greatly improved
Degree performance.But above-mentioned novel concrete based composites, is still tired limiting at the Research Concept of concrete, say, that still exist
The category of conventional cement material.
Summary of the invention
It is an object of the present invention to provide the preparation method of the composite light cement that a kind of profiled polymer structure strengthens, it is therefore an objective to obtain
Lightweight, high-strength cement constructional material.
The preparation method of the composite light cement that profiled polymer structure strengthens, realizes according to the following steps:
One, the making of polymer polymorphic structure: use deposition forming method that thermoplastic is processed into the sky with high stability
Between structure；Wherein thermoplastic is polyethylene, polypropylene, polrvinyl chloride, nylon or polyurethane；
Two, cement slurry makes: according to volume ratio 1 (1～4) (1～1.5) by Portland cement, fine aggregate and water
Stir；
Three, light cement is composite formed: being fixed in mould by polymer polymorphic structure, polymer polymorphic structure accounts for mould
Tool inner volume 0.1%～30%, cement injection slurry the most under vibrating conditions, after perfusion natural drying sizing, through die sinking,
Cleaning, repair type after i.e. complete the preparation of composite light cement that profiled polymer structure strengthens.
Discontinuous enhancing, independent of existing cement-base composite material system, is changed into continuous print and is strengthened phase by the present invention mutually,
The use intensity of cement it is effectively improved, it is achieved that cement based is multiple by the globality of polymer polymorphic structure and good pliability
The integral forming that condensation material and predetermined structure make, reduces the weight of structural member simultaneously, and technique is simple, have good can
Operability.
Present invention have an advantage that use continuous print polymer polymorphic structure network replaces discontinuous polymer fiber, by water
The mechanism and enhancement mechanism of cement-based composite material is improved as strengthening continuously the collaborative enhancing of phase, effectively by the independence enhancing of Discontinuous Reinforcement phase
Promote the serviceability of cement-base composite material；Eliminate the coarse aggregate in cement concrete, can effectively reduce the weight of material,
Loss of weight 40%-50%；Cement-base composite material uses filling type to shape, and does not change the mobile performance of cement slurry；Strengthen phase
Structure can freely design, composite and precast construction integral forming.To sum up, it in contrast to existing fibre reinforced cement base
Composite, has processing technology simple, low cost, and technical process designability is strong, uses abundant raw material, can effectively drop
The advantages such as the weight of low cement constructional material, are a kind of lightweights, and high-strength novel cement-based structural material enriches cement and builds
Build material category.
