Description

A kind of wood preservation film

Technical field

The utility model relates to wood preservation field, in particular to a kind of wood preservation film.

Background technique

The building structure of domestic Classical Gardens at present, since service life is more long, timber structure stability is by choosing War, some protects due to being negligent of, and the ancient building for having certain history culture permanent disappears.In order to preferably protect and rebuild And reinforce Wood construction structure.In the engineering construction specification that the Ministry of Construction, China formulates, new regulation is also made to wood preservation, with suitable The demand that timber uses is answered, this has certain facilitation to the development of wood preservation industry.

Ancient garden timber is exposed for a long time outside, and especially the south of the lower reaches of the Yangtze River weather is more moist, and timber is subjected to wind for a long time Solarization water leaching effect, easily generate corrode, it is rotten, blue the situations such as become, damage by worms, cause wooden structures built on the sand and use be safe hidden Suffer from.The body pillar of gardens ancient architecture, rod structure are all wooden structures, this just proposes very high want to the structural stability of timber It asks.

But present wood preservation has certain problems, first, traditional anticorrosive wood passes through direct injection preservative So that the timber short time reaches anti-corrosion effect and fills up wood internal gap, enhance wood preservation durability, effect often continues not It is long.Second, wooden construction is contacted with air etc. for a long time, cause it is wooden it is loose cause to rot, general preservative, which does not have, gives out light And waterproofness.Third, the preservative of existing timber addition is after a period of time, preservative is easy to be lost.

In view of this, it is really necessary to develop a kind of wood preservation film, to solve the above problems.

Preferably, the thickness of basement membrane and the first silicon oxide film is respectively 4 microns and 95 Ethylmercurichlorendimides, first layer and third layer Overall thickness is 45 microns.

Preferably, overlay is with a thickness of 8 microns.

Preferably, top layer A at least further includes one layer of heat resistant transparent film, and the heat resistant transparent film is that twin shaft is poly- to benzene two Formic acid ethylene glycol adipose membrane, the heat resistant transparent film is between polyvinyl alcohol film 1 and overlay 2.

Preferably, bottom C is ethylene-ethyl acrylate copolymer.

Preferably, polyvinyl alcohol film 1, overlay 2, the first transparent silicon oxide film 3, basement membrane 4, the second transparent Indium Silicon thin film 5 and heat sealable resin layer are coated with ultraviolet absorbing agent between film layer two-by-two, and the ultraviolet absorbing agent is hexichol first At least one of ketone and benzotriazole.

The utility model compared with prior art, the beneficial effect is that: have excellent intensity, heat resistance and economy, The excellent transparency and humidity resistance may remain in for a long time under high temperature and the weather of high humility, also have antiultraviolet Property, avoid timber loose rotten under sunlight irradiation for a long time, the transparency has more ornamental value.

Detailed description of the invention

Fig. 1 is the cross-sectional view according to wood preservation film described in the utility model.

Specific embodiment

The following describes the utility model in further detail with reference to the accompanying drawings, the aforementioned and other mesh of the utility model , features, aspects and advantages will be apparent, to enable those skilled in the art's refer to the instruction text real accordingly It applies.In the accompanying drawings, for clarity, shape and size can be amplified, and identical attached drawing mark will be used in all figures Note is to indicate the same or similar component.In the following description, such as center, thickness, height, length, front, back, rear portion, The words such as the left side, the right, top, bottom, top, lower part are to be based on the orientation or positional relationship shown in the drawings.Particularly, " high Degree " is equivalent to size from the top to the bottom, and " width " is equivalent to size from left to right, and " depth " is equivalent to be arrived in the past Size afterwards.These relative terms are to be not intended to need specifically to be orientated for convenience and usually.Be related to attachment, The term (for example, " connection " and " attachment ") of connection etc. refers to that these structures are fixed directly or indirectly to one another by intermediate structure Or the relationship and movable or rigidly attached or relationship of attachment, unless otherwise clearly stating.

Referring to Fig.1, wood preservation film includes:

Top layer A, middle layer B and the bottom C set gradually from top to bottom,

Wherein, top layer A includes polyvinyl alcohol film 1, overlay 2 and the first transparent Indium made of suppressing from top to bottom Silicon thin film 3；
