Description

Green house composite fibre insulation quilt

Technical field

The utility model relates to a kind of heat insulating products, especially for the insulation quilt of green house, belongs to the product for agriculture technical field.

Background technology

In recent years, along with improving constantly of agricultural cience and farming techniques, the chamber planting industry is fast-developing, and greenhouse structure and varieties of plant also have bigger variation.At present, greenhouse structure is made up of two big classes, and a class is Continuous building type shed greenhouse, and it also need rely on manually in the winter time and heat except that utilizing solar radiation; Another kind of is greenhouse by solar heat, and it mainly is to rely on solar irradiation that greenhouse temperature is provided, and keeps greenhouse temperature to need not manually to heat by insulation material.This greenhouse lighting and heat insulation effect are better, can use in Various Seasonal, different regions especially the northern area of China.Along with the chamber planting industry develops to scale, standardization, existing greenhouse heat-insulating material is outstanding day by day such as some problems that straw screen or mat, cotton-wadded quilt etc. in use reflects, be mainly reflected in following aspect: 1. heat-insulating property is poor, can't satisfy the crop planting requirement that greenhouse temperature is had relatively high expectations; 2. do not have the ability that waterproof is resisted sleet; 3. difficulty is used, carries, taken care of to big, the heavy of the volume of insulation material (as straw screen or mat) own; 4. the life-span is short, cost is high, be not easy to mechanization produces in batches; 5. straw screen or mat easily goes mouldy, and produces mould thus, and contaminated environment increases the crop pest opportunity.In sum,, must the insulation material of existing green house be improved, to satisfy the needs of chamber planting industry to scale, standardization development for guaranteeing the sustainable development of chamber planting industry.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the defective of above-mentioned prior art and a kind of green house composite fibre insulation quilt that is incubated rate height, waterproof, light weight is provided.

The alleged problem of the utility model is solved by following technical scheme:

A kind of green house composite fibre insulation quilt, its special feature is: comprise waterproof top layer 2 in 1, constituting, go up heat-insulation layer 3, hold back layer 6 and following heat-insulation layer 7, described each layer closes admittedly in its edge, described waterproof top layer and last heat-insulation layer are bonding, and the described layer that dams forms the air chamber 1 that dams at heat-insulation layer up and down between the heat-insulation layer, respectively with up and down.

Above-mentioned green house composite fibre insulation quilt is set up insulation bottom 8, and the insulation bottom is positioned at heat-insulation layer bottom down, and forms pair air chamber 9 that dams between following heat-insulation layer.

Above-mentioned green house composite fibre insulation quilt is equipped with strength layer 4, the mutual driving fit of described strength layer and heat-insulation layer in described upper and lower heat-insulation layer and the insulation bottom.

Above-mentioned green house composite fibre insulation quilt, described upper and lower heat-insulation layer and insulation bottom are the composite fibre felt layers, the described layer that dams is PVC soft polyethylene film or aluminium foil layer, and described waterproof top layer is PE, EVA high-strength polymer layer, and described strength layer is a PP polypropylene fibre base fabric.

Above-mentioned green house composite fibre insulation quilt, described upper and lower heat-insulation layer and insulation bottom surface bonded nonwoven layer 5.

The utility model utilizes complex fiber material to make, its original layered chamber structure design is compared with existing greenhouse heat-insulating material, has significant progress in all many-sides, its main feature is embodied in following aspect: 1. heat-insulating property is outstanding, and the utility model on average can improve 4～6 ℃ than straw screen or mat heat insulation effect, and the insulation rate can reach 76%, test shows, under the situation of outdoor temperature-30 ℃, the booth that adopts the utility model to cover, temperature of shed cover than straw screen or mat will exceed 3～5 ℃; 2. in light weight, general straw screen or mat weight is 3.5～4.5Kg/M ², the utility model weight is 1.2Kg/M ², since in light weight, reduced laying labour intensity, and can carry out sheet connection mechanization and use; 3. have advantages of good waterproof property, show through rainproof flow rate test, it is hydrophobic, the drench water-based is good, does not retain, and drenches back one hour end face free from dampness; 4. intensity height, long service life, the utility model tensile strength can reach 800～900N/5CM ², in 8～10 years service life, be higher than 2～3 times of straw screen or mat; 5. use cost is low, because long service life, so use cost is about 50% of common straw screen or mat.In addition, the utility model carries out fire protection flame retarding, antistatic, anti-oxidant, acid and alkali-resistance processing in process of manufacture, thereby has improved the safety of using, and is mildew and rot, free from environmental pollution in the use, and recyclable.These characteristics makes the utility model as greenhouse insulation product of new generation, and its economic benefit and social benefit are all very considerable.
