Abstract
The invention discloses a kind of special white master batch of infrared reflection film, is prepared by each dispensing of following mass percent：Low density polyethylene (LDPE) 26.9-46.5%, titanium dioxide 50-70%, age resister 0.1-0.5%, dispersant 3%.Simple production process of the present invention, can continuous production, the whiteness of product is good, dispersion degree is high, weatherability is strong, infrared-reflecting power is strong.Mulch also has extraordinary weatherability and reflection infrared effect in practical applications made of the Masterbatch, adds the yield of crop, shortens the maturity period of crops.The special white master batch of infrared reflection film of the present invention has boundless application prospect in agricultural production.
Description
Technical field
The present invention relates to master batch manufacturing technology field, more particularly to a kind of special white master batch of infrared reflection film.
Background technology
Since 1978 introduce film-mulching technique from Japan, agriculture field is popularized at home rapidly for the application of mulch.
Mulch not only has the function that insulation, moisturizing, improves fertilizer efficiency, additionally it is possible to effectively prevents the growth of weeds, the harm of pest, is improved
Light and heat condition near the ground, makes agricultural product keep stable high yield, and great contribution is made that for the agricultural in China and economic development.Ground
Film is fabricated using high molecular polymer, and Masterbatch is important high molecular material colouring agent, so that coloured for mulch, can
To effectively improve light conversion ratio, increase the yield of crops.
Research shows that infrared ray has growth and development of plants important influence, its fuel factor produced can be supplied to plant life
Heat needed for long development.Under the irradiation of infrared ray, the maturation of crops can be made to reach unanimity, improve the ripe fruit rate of crop.
However, infrared ray is absorbed by soil or mulch more after sunlight is radiated at ground, therefore, if can increase the infrared external reflection of mulch
Effect, it is possible to the further yield of increase crops.
The content of the invention
In order to increase the infrared-reflecting power of mulch, the present invention provides a kind of special white master batch of infrared reflection film,
With good reflection infrared effect.Technical scheme is as follows：
A kind of special white master batch of infrared reflection film, is prepared by the dispensing of following mass percent：Low density polyethylene
Alkene 26.9-46.5%, titanium dioxide 50-70%, age resister 0.1-0.5%, dispersant 3%.Wherein described low density polyethylene
The density of alkene is 0.912-0.923g/cm3。
Preferably, the titanium dioxide is rutile type titanium white, particle diameter is 0.8-1.3 μm, and the titanium white powder purity is high,
Particle diameter is in near-infrared elder generation wave-length coverage, strong to the albedo of infrared ray.Masterbatch is just to red made of the titanium dioxide
Outside line has the reflection of maximum intensity, and then mulch could be by the infrared reflection in sunlight to agriculture made of the Masterbatch
On crop.In addition, the titanium dioxide high refractive index up to 2.7, has very strong covering power, weatherability, heat resistance, uvioresistant ability,
It not only can guarantee that dispensing process from heat damage, moreover it is possible to make Masterbatch that there is the weatherability and whiteness of higher level.
Preferably, the titanium dioxide particle diameter is 1.0 μm, there is optimal albedo to infrared ray.
Preferably, the age resister includes Hinered phenols oxidant, hindered amine as light stabilizer and epoxy anti-yellowing agent,
Make the Masterbatch that there is more longlasting anti-aging, anti-oxidant, uvioresistant, yellowing-resistant ability, make product appearance more longlasting more beautiful
See.
Preferably, the dispersant is one or both of Tissuemat E, stearic acid, increase low density polyethylene (LDPE),
The dispersion degree of titanium dioxide and age resister, makes molding Masterbatch whiteness higher.
A kind of preparation method of the special white master batch of infrared reflection film, comprises the following steps：
Step 1：Various dispensings are added in mixer, speed of agitator is 900-1100 revs/min, and mixing time is
3-5 minutes, dispensing is uniformly mixed；
Step 2：Screw extruder is heated to 250-280 DEG C, constant temperature was added in step 1 and mixed after 20-30 minute
Dispensing afterwards, starts to extrude, after being cooled by water granulating and forming；
Step 3：Masterbatch after shaping is put into vibrating screen to go out the non-uniform particle of size, to color up to specification
Master batch is tested for the property, through being packed after the assay was approved with Aluminum-plastic composite bag.
Beneficial effects of the present invention are：Produce obtained Masterbatch infrared-reflecting power is strong, whiteness is good, dispersion degree is high,
Weatherability is strong, and preparation process is simple；Can continuous production；The mulch of master batch using the present invention production have infrared reflectivity it is high,
Many advantages, such as weatherability is strong, by increasing capacitance it is possible to increase crop yield rate, shortens as processing maturation period.
