Abstract
The invention discloses a high-strength water-proof durable composite material, which consists of an OPP (Oriented Polypropylene) printing film, an LDPE (Low-Density Polyethylene) layer and cotton cloth from top to bottom in sequence. Compared with the prior art, the high-strength water-proof durable composite material has the advantages of high strength, capability of carrying and packaging larger objects without damage, long service life, good sealing property, low cost, wide application range and capability of being used for manufacturing shopping bags, thermal insulation bags, packaging bags, shopping baskets and the like. The preparation method is simple, and industrial production can be realized.
Description
Technical field
The present invention relates to a kind of composite, relate in particular to the durable composite of a kind of high-strength waterproof.
Background technology
Along with growth in the living standard; People require also increasingly high to the material of daily necessities; Common material can not satisfy people's demand, and for example, people are in the supermarket, when food is bought in the food market; Generally be to use common shopping bag (material is a cotton) or polybag, its function only limits to carry and pack a spot of article.If the thing of buying is heavier or harder corner angle are arranged, common shopping bag or polybag easy damage in the process of transporting can't continue to use.
Summary of the invention
Goal of the invention: in order to solve the deficiency of prior art, the invention provides the durable composite of a kind of high-strength waterproof, to overcome material not long shortcoming in service life in the prior art.
The present invention also provides the preparation method of the durable composite of above-mentioned high-strength waterproof.
Technical scheme: in order to realize above purpose, the durable composite of high-strength waterproof of the present invention, it is made up of OPP print film, LDPE layer, cotton from top to bottom successively.
The thickness of described OPP print film is 15 ~ 40um; The thickness of described LDPE layer is 20 ~ 50um; The thickness of described cotton is 0.4 ~ 0.8mm.
Make the method for the durable composite of above-mentioned high-strength waterproof, comprise the steps:
1, pattern is printed on becomes the OPP print film on the OPP film;
2, LDPE is extruded under 320～350 ℃ condition, drench both are closed in pouring, form the LDPE layer.
Beneficial effect: the present invention compared with prior art has the following advantages: intensity is high, can be used for carrying and pack more a large amount of article and can not damage long service life; Good airproof performance, cheap, the scope of application is extensive; Can be used for making shopping bag, insulated bag, packaging bag, shopping basket etc.Preparation method of the present invention is simple, can realize suitability for industrialized production.
