Description
Technical field
The invention discloses a kind of preparation method of weather-proof antiglare shield, belong to technical field of board processing.
Background technology
Glare screen is the important safety devices of highway, its main function is to prevent highway night two-way meeting
When car light strong illumination, cause Driver Vision function or eyesight moment to reduce, produce uncomfortable illumination sense and dizziness.At present,
Anti-Glare Devices in Freeway mainly has three classes：Hedgerow, antiglare shield and anti-dazzle net.Wherein hedgerow glare screen refers in highway
Middle ground band serike, hedgerow not only has preferable antiglare effect, but also can improve landscape, but invests big, climate
Influence greatly, to need long-term later maintenance.Anti-dazzle net is netted metallic spacer, is divulged information, but antiglare effect is poor, easy accumulated snow.
Therefore, antiglare shield is due to that antiglare shield has cheap, good appearance, and antiglare effect is good, and the advantages such as maintenance cost is low, become
The most common glare screen of highway.
The material of existing antiglare shield is mainly steel, engineering plastics and fiberglass etc..Wherein, steel antiglare shield is easily split
The problems such as gap, attachment peel off, corrosion, and easily cause secondary injury during the fracture of steel antiglare shield；And engineering plastics antiglare shield
Then resistance to ag(e)ing is poor, easy to change, ant wind load is low.Fiberglass is still the main selection of antiglare shield at present, although it has firmly
Spend high, corrosion-resistant, resistance to dust storm abrasion, can resist the advantages of wind load, but higher price, and raw material epoxy resin and glass fibre
Non-renewable resources are all from, can not be recycled after corrupted, considerably increase the maintenance operation cost of highway.Research is opened
Green-emitting, renewable, low-cost substrates antiglare shield are to realizing that China's highway low-carbon, safety, sustainable development have weight
Want realistic meaning.
Therefore, the shortcomings that how improving conventional dazzle prevention plate mechanical property and bad weatherability, to obtain more high combination property
Antiglare shield, be its promote be applied to broader field, meet industrial production demand urgent problem to be solved.
The content of the invention
The present invention solves the technical problem of：The shortcomings that for conventional dazzle prevention plate mechanical property and bad weatherability,
Provide a kind of preparation method of weather-proof antiglare shield.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
（1）It is 1 in mass ratio：5~1：After 10 mix grading granulated cork with enzyme liquid, constant temperature stirring enzymolysis, then through enzyme deactivation, mistake
Filter, washing and drying, obtain enzymolysis granulated cork；
（2）It is 1 in mass ratio：10~1：After 12 mix enzymolysis granulated cork with unsaturated carbonate hydrogen calcium solution, ultrasonic immersing 3~
5h, then it is filtered, dry, obtain dipping granulated cork；
（3）Count in parts by weight, take 100~150 parts of dipping granulated corks, 10~15 parts of ethyl orthosilicates, 8~10 parts of titaniums successively
Sour four butyl esters, 8~10 parts of isocyanates, 8~10 parts of phenolic resin, freeze-thaw circulation 4~6 times after mixing, obtain defrosting cork
Particle；
（4）Defrosting granulated cork is paved in mould, it is hot-forming after precompressed, obtain slab；
（5）By gained slab, modifier treatment 3~5 days, re-dry to constant weight are to obtain the final product weather-proof anti-dazzle under constant-temperature constant-humidity environment
Plate.
Step（1）The grading granulated cork is formed by the raw material grading of following parts by weight：20~30 parts of particle diameters are 2
The granulated cork of~4mm, the granulated cork that 20~30 parts of particle diameters are 0.6~0.8mm, 30~50 parts of particle diameters are 0.1~0.3mm's
Granulated cork.
Step（1）It is 1 in mass ratio by pectase and deionized water that the enzyme liquid, which is,：100~1：150 configurations form.
Step（2）The unsaturated carbonate hydrogen calcium solution configuration process is：It is 20~25 DEG C of water by calcium bicarbonate addition temperature
In, until calcium bicarbonate is not redissolved, filters, obtain filtrate, be unsaturated carbonate hydrogen calcium solution.
Step（3）The isocyanates is toluene di-isocyanate(TDI), methyl diphenylene diisocyanate or trimethyl cyclohexane
Any one in diisocyanate.
Step（3）The phenolic resin is phenolic resin 2123, any in phenolic resin 2127 or phenolic resin 2130
It is a kind of.
Step（4）The prefabricating condition is：Preload pressure is 1.2~1.6MPa, and precompressed temperature is 25~35 DEG C, during precompressed
Between be 2~4min.
Step（4）The hot pressing condition is：Hot pressing pressure is 8~12MPa, and hot pressing temperature is 140~160 DEG C, during hot pressing
Between be 20~30min.
Step（5）The constant-temperature constant-humidity environment is：Temperature is 25~30 DEG C, and relative humidity is 55~60%.
The beneficial effects of the invention are as follows：
（1）Technical solution of the present invention is using granulated cork as basis material, first with pectinase enzymatic hydrolysis, makes between cork cell
Cell membrane occur degrade to a certain degree, so that space between cells is widened, easy to which in subsequent processes, each active ingredient is quickly filled
Divide and penetrate into inside plant cell, recycle calcium bicarbonate solution immersion, plant cell is absorbed calcium bicarbonate solution, through true
After sky is dry, moisture evaporation, calcium bicarbonate in plant cell internal crystallization, then again by with ethyl orthosilicate, four fourth of metatitanic acid
Ester, isocyanates and phenolic resin mixing, and coordinate freeze-thaw circulation, during freeze-thaw, the heat expansion of system is cold
Contracting acts on, and the materials such as ethyl orthosilicate is penetrated sufficiently into plant cell inside and space between cells, in follow-up hot pressing,
Calcium bicarbonate is thermally decomposed, and is produced carbon dioxide and water, after moisture is contacted with ethyl orthosilicate, butyl titanate, is made two
Person hydrolyzes, and it is thin that the calcium carbonate that hydrolysate silica and titanium dioxide and calcium bicarbonate decomposition produce can be filled in plant
Intracellular portion, and can be under the cementation of isocyanates and phenolic resin, in plant cell film surface formed with machine-inorganic compounding
Film, on the one hand plays and bonds and support plant cell membrane, improves the purpose of system mechanical property, on the other hand, can make system
The carbon dioxide that inside produces is closed in inside plant cell, is made inside plant cell in CO 2 gas-shielded
Under state, so that plant cell volume expanded, space between cells reduces, so that it is internal effectively to avoid corrosive medium from entering, makes production
Product weather resistance further improves, and isocyanates can also decompose the water produced with calcium bicarbonate in system and react, and generates
Carbon dioxide, makes plant cell volume further increase, while its reaction product can promote phenolic resin in the cell
The rapid curing in portion, so as to fulfill the supporting role to plant cell, makes product mechanical property further be lifted.
（2）In technical solution of the present invention, the generation of titanium dioxide, under the effect of outdoor ultraviolet catalytic, can have system
Standby excellent antibacterial microbial corrosion resistance energy, and the titanium dioxide generated is closed in inside plant cell, is only using process
In not easily run off, while being positively maintained product mechanical property, product service life is effectively extended.
