Abstract
The present invention relates to a film and a production process thereof, which belongs to the technical field of environmental protection and is invented for solving the problem of white pollution. The film of the present invention is characterized in that the film is composed of a base layer with small holes and a degradable plastic sealing the small holes in the base layer. The process of the present invention comprises the following step: the small holes are pricked in the base layer of the film by a needle roller first, and then the degradable plastic is coated. The film is used for agriculture, packaging and daily life.
Description
The invention belongs to environmental protection technical field, relate to improvement agricultural film.
Make the greenhouse with the humiture environment inside and outside the compartment with plastic sheeting on the agricultural; Also a large amount of plastic sheeting and goods thereof used in commodity packaging and daily life.(when not considering environmental protection) plastic sheeting is practical and is cheap; But the plastic sheeting natural degradation is chronic, and discarded plastic sheeting is waterproof airtight in soil, influences the root system development of plant, and natural environment has been formed " white pollution ".For avoiding white pollution, what people considered now mainly is the component of polymer that changes or change plastic sheeting, developed multiple degradation plastic, mostly being seen report is the converted starch composition, the inventor does not still understand the situation of its cost and properties of product, and it is still universal only to know that it is used at present.
The purpose of this invention is to provide a kind of film that is easy to be degraded to the water-permeable and air permeable degree.
The object of the present invention is achieved like this:
A kind of water-tight and air-tight film, it is characterized in that it is made of two kinds of plastics at least, first kind of film forming basic unit of plastics has been covered with the ventilative aperture of porous of suitable spacing in this basic unit, second kind of plastics is easy to degrade, the aperture in its airtight above-mentioned basic unit.
Its production method is:
The plastic sheeting of existing single component is made it to become the basic unit of the present invention's film through the porcupine roller that suitably is distributed with some little pins on its roll surface, minimum a kind of method of passing through spraying again, crossing methods such as roller coat, dip-coating is to the single or double coating liquid state of this basic unit or second kind of plastics of thickness attitude, and treating promptly becomes film of the present invention after second kind of plastics condenses.
According to above-mentioned production method, on the production equipment of existing plastic sheeting, install corresponding mechanism additional, then production process can be gone on foot to film one of the present invention by plastic raw materials and finish.
By above-mentioned product structure and production method thereof as can be known, film of the present invention is easy to be degraded to the water-permeable and air permeable degree, and the corresponding harm of plant has been obtained solution, and its environmental benefit is good; Its production cost increases seldom, has the market competitiveness; The serviceability of real aspects such as its product strength and the existing plastic sheeting that causes white pollution specific energy mutually keep constant substantially; It will be easy to promote, and can benefit society.

Introduce product structure of the present invention and production method thereof in detail below in conjunction with accompanying drawing:
The structure of product:
Its plane is shown in Fig. 1, has been covered with the ventilative aperture 2 of porous of suitable spacing in the basic unit 1 of the film of first kind of plastics formation.Only being this aperture 2 is not had second kind of plastics 3 promptly to become as shown in Figure 2 section situation by the remainder of second kind of plastics 3 airtight while film, and this is first kind of form of product structure; The one side that this aperture 2 has been covered basic unit 1 by 3 airtight while of second kind of plastics, second kind of plastics 3 promptly becomes section situation as shown in Figure 3, and this is second kind of form of product structure; This aperture 2 has been covered two section situations that promptly become as shown in Figure 4 of basic unit 1 by 3 airtight while of second kind of plastics, second kind of plastics 3, and this is the third form of product structure.
Production technology:
With the plastic sheeting 10 of existing single component through suitably being distributed with the porcupine roller 5 of some little pins 50 on its roll surface, make it to become the basic unit 1 of the present invention's film, make it by by the top of crossing roller 6 of the immersion liquid state of part or second kind of plastics 3 of thickness attitude, second kind of plastics 3 promptly becomes second kind of form of product structure as shown in Figure 3 after condensing in the basic unit 1 again.Final product is rolled onto on the roller 4, as shown in Figure 5.
With the plastic sheeting 10 of existing single component through suitably being distributed with the porcupine roller 5 of some little pins 50 on its roll surface, make it to become the basic unit 1 of the present invention's film, make it by by the bottom of crossing roller 6 of the immersion liquid state of part or second kind of plastics 3 of thickness attitude, second kind of plastics 3 promptly becomes the third form of product structure as shown in Figure 4 after condensing in the basic unit 1 again.Final product is rolled onto on the roller 4, as shown in Figure 6.
With the plastic sheeting 10 of existing single component through suitably being distributed with the porcupine roller 5 of some little pins 50 on its roll surface, make it to become the basic unit 1 of the present invention's film, after condensing in the basic unit 1, promptly become second kind of form of product structure as shown in Figure 3 by nozzle 31 to liquid 3, the second kinds of plastics 3 of second kind of plastics of spraying in the basic unit 1 again.Final product is rolled onto on the roller 4, as shown in Figure 7.
If will obtain first kind of form of product as shown in Figure 2, can after applying second kind of plastics 3, before condensing, it scrape off second kind of unnecessary plastics 3 with scraper plate, and treating promptly becomes product shown in Figure 2 after it condenses again.
Described first kind of plastics are to be difficult for degraded.
