Description
Technical field
The present invention relates to a kind of insulation material of the agricultural booth side skirt film based on polyethylene, belongs to the life of plastic sheeting product
Production field.
Background technology
Because the northern area of China winter climate is cold, it is not suitable for plant growth, in order to boost agricultural yield, reaches precocious
Volume increase, the purpose of abundant common people's dining table, the effect of warmhouse booth are particularly significant.For a long time, warmhouse booth covering material uses
Cotton-wadded quilt, felt etc., with the development of polymer material science, insulation material, which updates, to be accelerated, and has engendered that polyethylene covers
Film, polyvinyl chloride overlay film, ethylene-vinyl acetate copolymer composite membrane etc., but these covering materials generally conduct oneself with dignity it is larger, it is right
Temperature change is sensitive, and heat insulating ability is poor, and service life is shorter.Particularly greenhouse side skirt film, it is right because it is often crimped operation
Pull resistance, the requirement of resistance to ag(e)ing are especially harsh, and common greenhouse side skirt membrane material heat insulating ability quality itself is not on the market at present
One, after a particular period of use, material is necessarily damaged in itself, and its light transmission, heat-insulating property etc. are all notable
Decline, studies have found that, winter greenhouse have more than 60% heat energy be due to side skirt film heat-proof quality difference and scatter and disappear, therefore
In order to provide the greenhouse side skirt membrane material of a kind of lightweight, tension, good heat insulating, the invention provides a kind of polyethylene foam material
Material, has preferable pull resistance and heat-insulating property, the heat that can effectively reduce inside greenhouse scatters and disappears, and lifts the heat insulating ability of facility
Energy.
The content of the invention
The defects of purpose of the present invention is for agricultural booth side skirt membrane material in the prior art, there is provided one kind is based on poly- second
The insulation material of the agricultural booth side skirt film of alkene, there is preferable pull resistance and heat-insulating property, service life length, can effectively drop
Heat inside low greenhouse scatters and disappears, and improves the heat-insulating property of facility.
The present invention is achieved through the following technical solutions：
A kind of insulation material of the agricultural booth side skirt film based on polyethylene, include the raw material of following parts by weight：Polyethylene
65-80 parts, 4,4- OBSH 2-4 parts, zinc acetate 1-3 parts, nano titanium oxide 2-6 parts, dripless agent 4-8 parts, resistance
Fire agent 2-7 parts, antioxidant 5-10 parts.
Wherein described 4,4- OBSHs are more preferably 2.5-3,5 parts, and zinc acetate is more preferably
1.5-2.5 part；
Wherein described dripless agent is ethylene oxide adduct, sorbitan fatty acid ester, Vinlub 73
Etc. one or more therein；
Wherein described fire retardant is alkylphosphonate, aryl phosphate, dicyclopentadiene, methylene bromide, magnesium hydroxide, boron
One or more in hydrochlorate etc.；
Wherein described antioxidant is alpha-tocopherol.
The present invention also provides a kind of preparation method for preparing the above-mentioned insulation material for agricultural booth side skirt film, and step is such as
Under：At a temperature of 170 DEG C -210 DEG C, first polyethylene and 4,4- OBSHs, zinc acetate are sufficiently mixed, add and receive
Rice titanium dioxide, dripless agent, fire retardant, less than 100 DEG C are cooled to after high speed shear is well mixed, adds antioxidant, again
Extruded, stretched after stirring, that is, obtain finished product.
Insulation material main body provided by the present invention for agricultural booth side skirt film is polyethylene foamed, with the market its
His expanded material is different, and insulation material of the present invention is not easy to lose, the present invention is by adjusting the species of raw material and containing from heavy and light
Amount so that abscess is fine and closely woven, stably, not only causes material to have good toughness in itself, also effectively reduces the heat conduction system of material
Number, substantially increases heat insulation effect, and in addition, insulation material provided by the present invention also has good water proof, uvioresistant
Effect, service life length, and process simply, cost is cheap.
