Description
Technical field
The invention discloses a kind of impact resistance light weight composite floors, belong to building material technical field.
Background technique
Currently, requirement of the people to home life is also higher and higher, especially with the increasingly raising of people's living standard
It is related to floor, influence of the quality on floor to living environment is very big, and floor type in the market is more and more, presently commercially available
Floor it is relatively popular be usually two class of solid wooden floor board and composite floor board.
The index of floor performance is also improved day by day now, still, there is also many problems, solid wooden floor board main body is entirely
Solid wood causes at high cost and weight very big, cannot function as floor on some very high buildings and uses, in addition, anti-
Aqueous energy is relatively rough, preferable effect is not achieved, for another example the patent of invention of Publication No. 1535813 discloses a kind of poly- ammonia
Ester-rigid plastics composite floor board, although waterproofness, wearability, adhesiveness are preferable, in addition it is light also to become comparison for quality, at
Type process requirement uses multiple molds, and forming operation step is more, subsequent also to demould, and the entire production time is very long, efficiency
It is low, and the probability to go wrong in the process is also high, influences to produce, and polyurethane skin layer density should not be too large, if mistake
Greatly, it is easy to deform low density plastic bottom layer, and preferable wearability, adhesiveness cannot be played by so that its density is become smaller.At present
Traditional part light weight composite floor problem bad there is also shock resistance, therefore also need further to study it.
Summary of the invention
The present invention solves the technical problem of: for the bad problem of traditional lightweight composite floor board shock resistance,
Provide a kind of impact resistance light weight composite floor.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that:
A kind of impact resistance light weight composite floor, is made of the raw material of following parts by weight:
60~80 parts of phenolic resin
20~30 parts of diluent
Modified 20~30 parts of sisal fiber powder
5~8 parts of calcium stearate
Modified montmorillonite used 10~20 parts
10~20 parts of expanded and vitrified small ball
8~10 parts of curing agent
8~10 parts of emulsifier
30~40 parts of polyvinyl alcohol liquid
The preparation process of the impact resistance light weight composite floor are as follows: each raw material is weighed by raw material composition, by phenolic resin, dilution
Agent, modified sisal fiber, modified montmorillonite used, calcium stearate, expanded and vitrified small ball, curing agent, emulsifier and polyvinyl alcohol liquid stir
Mixing is mixed, injection molding is hot-forming, demoulds to get impact resistance light weight composite floor.
The phenolic resin is any one in 3201 phenolic resin or 2123 phenolic resin.
The diluent is ethyl alcohol, methanol, any one in ethylene glycol or butanol.
The preparation process of the modified sisal fiber powder are as follows: sisal fiber is crushed, is sieved, sisal fiber powder is obtained, by sword
Flaxen fiber powder, biogas slurry, sucrose, glycerol, water mixed fermentation are filtered, and are washed, and are freezed, and are crushed, and are sieved, dry, must pre-process sisal hemp
Fiber powder；Pretreatment sisal fiber powder is stirred with butyl titanate, filters, washs, dry, ball milling is sieved to get changing
Property sisal fiber powder.
The modified montmorillonite used preparation process are as follows: ca-montmorillonite and water are stirred, sodium carbonate is subsequently added into, it is permanent
Temperature is stirred to react, and octadecyltrimethylammonium chloride is then added, and water bath with thermostatic control processing is dry, obtains modified montmorillonite used.
The curing agent is hexamethylenetetramine, any one in diethylaminopropylamine or triethylene tetramine.
The emulsifier is polyethylene glycol, Si Pan -80, alkyl glycosides or neopelex any one.
The beneficial effects of the present invention are:
The present invention is by adding modified sisal fiber powder, and during the preparation process, firstly, by sisal fiber powder, biogas slurry, sucrose is sweet
Oil, water mixed fermentation, the enzyme activation sisal fiber generated using the microorganism in biogas slurry so that binding force between sisal fiber into
The decline of one step recycles liquid nitrogen frozen processing water to then pass through ball milling so that forming ice crystal in fibrocyte, makes in cell wall
Ice crystal be under pressure effect and rupture, make fiber separation at micro/nano level fibrous crystal palpus, will then pre-process sisal fiber
Powder is stirred with butyl titanate, and butyl titanate penetrates into inside uncracked fibrocyte, and the water with cell interior
Divide reaction, generates titanium dioxide deposition portion in the cell, using ball milling, the titanium dioxide and ball milling that are deposited in fibrocyte
Extruding force is formed between pearl, so that cell rupture, so that fibrous crystal palpus of the uncracked fiber separation at micro/nano level, so that
Fiber adequately separates, and in use, after matrix is by external force, fiber is provided powerful by existing chemical bonding
Bridging traction, with the increase of external force, denaturation increases, and occurs crack therewith, and the fiber at crack starts slowly chemical unsticking,
Continue to absorb energy by the physical friction power of interface between fiber and matrix after unsticking, be continuously applied external force, deformation gradually increases
Greatly, and fiber constantly consumes and absorbs energy by physical friction cohesive force so that the shock resistance of system obtain into
The promotion of one step.
