A kind of fluorescence cement brick and preparation method thereof
Technical field
The present invention is more particularly directed to a kind of fluorescence cement bricks and preparation method thereof, belong to the technology of preparing neck of building decoration materials
Domain.
Background technique
With the development that national economy is lived, material used in Outdoor Design has been directed to steel, non-ferrous metal, change
A variety of industries such as work, weaving, timber, ceramics, plastics, glass.People for Outdoor Design theme tone emphasize with again
New material depending on, it is also desirable to great individual character again moderate cost is realized.List is with regard to wall, ground decoration one, available material
Huge number, such as glaze for glazed tile, marble, granite finishing brick etc., but above-mentioned material have been difficult to newly on decorative effect
Breakthrough, and cost is higher;It is difficult to use in exterior finish.Cement brick is a kind of common floor decorative material, and matter is hard, holds
Weight is small, and pressure resistance is wear-resisting, and can be moisture-proof.With economic continuous development, requirement of the people to quality of the life is higher and higher, present city
Though there is luminous cement brick on field, it is shone using LED, and need to being powered, it is luminous to carry out, and major applications are in square, dance hall etc.
Public arena has some potential safety problems.
Summary of the invention
The purpose of the present invention is to provide a kind of fluorescence cement bricks and preparation method for having illumination functions at night.
Technical solution of the present invention:

The present invention is added to fluorescent powder when preparing surface layer;To prepare a kind of cement for having illumination functions at night
Brick.Meanwhile The present invention reduces the dosages of water-soluble epoxy resin in surface layer, and a small amount of part PLA- is added to when preparing bottom
PEG;The dosage of organic matter is reduced, the gap between its air shrinkage value and surface layer air shrinkage value can be effectively reduced;To make itself and face
Layer can be preferably bonded.The present invention keeps the interfacial surface tension of surface layer and bottom mutual by adjusting the raw material of surface layer and bottom
Cooperation further increases its integral strength to reach preferably adhesive effect.
Above-mentioned anticracking cement brick, it is preferred that
The surface layer, by following weight match material be prepared: 50 parts of phosphor aluminate cements, 18 parts of sand, 14 parts it is glimmering
Light powder, 8.1 parts of water-soluble epoxy resins, 22-23 parts of water, 0.21 part of EVA tackifier, 0.42 part of high-efficiency water-reducing agent of poly-carboxylic acid,
0.07 part of adjustable solidification agent;
The bottom is prepared by the material that following weight matches: 28 parts of sulphate aluminium cements, 12 parts of sand, 18 parts of potteries
Porcelain particle, 12 parts of flyash, 18-21 parts of water, 1 part of PLA-PEG, 0.4-0.5 parts of EVA tackifier, 0.3-0.4 parts of polycarboxylic acids are efficient
Water-reducing agent, 0.07 part of adjustable solidification agent.Under this conditions of mixture ratios, the properties of cement brick are more preferable.
Above-mentioned anticracking cement brick, is preferably prepared by following methods:
(1) material for being used to prepare bottom, surface layer is uniformly mixed respectively, obtains slurry A and slurry B;
(2) mould inner wall brushes release agent, and slurry A is injected mold, stands 30-60s after vibration is flat;It is then injected into slurry B,
Vibration is flat;Then standing 2 hours allows it tentatively to condense, and conserves 3 days after initial set, finally demoulds, dry 8 days.
Preparation method of the invention first injects base pastes, reinjects surface layer slurry;To make a small amount of tree in fabric
Rouge is diffused into bottom in condensation process;To improve the performance of bottom.And standing 30-60s therein is diffused to limiting
The amount of the resin of bottom, to guarantee the content of resin in surface layer.
Beneficial effect
Fluorescence cement brick of the invention, has illumination functions;It is closely bonded between its each layer, the probability in crack occurs in finished product
It is low;With good water-fast acid resistance, stronger cracking resistance and flexural strength are indeformable, colour-fast.With it is at low cost, environmentally friendly,
The advantages that meeting the industrial policy of sustainable development.It can be widely applied to the decoration of metope, floor surface etc..
