Abstract
The invention discloses a waterproof durable composite material which is sequentially composed of an OPP (oriented polypropylene) printing film, a first LDPE (low-density polyethylene) layer, a woven fabric and a second LDPE layer. Compared with the prior art, the invention has the advantages of water resistance, moisture resistance, high strength, high fastness, long service life, favorable sealability, low price and wide application range, can be used for carrying and packaging larger objects without damage, is convenient for cleaning, and can be used for manufacturing knapsacks, haversacks, shopping bags, insulating bags, packaging bags, shopping baskets and the like. The preparation method is simple and can implement industrial production.
Description
Technical field
The present invention relates to a kind of composite, relate in particular to a kind of waterproof durable composite.
Background technology
Along with growth in the living standard, people require also more and more higher to the material of daily necessities, common material can not meet people's demand, for example, the knapsack of people's every day use or satchel etc., time on rainy day ratio be easier to into water, may drench the article in bag, and because intensity is little, be very easy to damage, after especially making moist, can reduce service life.
Summary of the invention
Goal of the invention: in order to solve the deficiencies in the prior art, the invention provides a kind of waterproof durable composite.
The present invention also provides the preparation method of above-mentioned waterproof durable composite.
Technical scheme: in order to realize above object, waterproof durable composite of the present invention, it is comprised of OPP print film, a LDPE layer, woven cloth, the 2nd LDPE layer from top to bottom successively.The thickness of described OPP print film is 15 ~ 40um; The thickness of a described LDPE layer is 20 ~ 50um; The thickness of described woven cloth is 10 ~ 20um; The thickness of the 2nd described LDPE layer is 20 ~ 50um.
The method of making above-mentioned waterproof durable composite, comprises the steps:
A, pattern is printed on and on OPP film, becomes OPP print film;
B, LDPE is extruded under the condition of 320～350 ℃, drench in woven cloth, form the 2nd LDPE layer;
C, LDPE is extruded under the condition of 320～350 ℃, drench between OPP print film and the another side of woven cloth both are closed in pouring, form a LDPE layer.
Beneficial effect: the present invention compared with prior art has the following advantages: waterproof and dampproof, intensity is high, fastness is strong, can be used for carrying and packs relatively large article and can not damage long service life, good airproof performance, easy to clean, cheap, the scope of application is extensive, can be used for making knapsack, satchel, shopping bag, insulated bag, packaging bag, shopping basket etc.Preparation method of the present invention is simple, can realize suitability for industrialized production.
