Problems solved by technology

[0003] Wood is a kind of natural organic material, there are many fibers in wood, and there are many gaps, which will cause the hardness, anti-corrosion performance, insect-proof performance, waterproof performance and dimensional stability of wood to be not good enough. The existing method is Apply a layer of paint on the surface of the wood. Once the paint is destroyed, the performance of the coating on the wood will disappear immediately, and the wood will also have the above defects.

Embodiment 1

[0027] The manufacture method based on oxime end-blocking ceramic wood comprises the following steps:

[0028] (1) Prepare prepolymer, react 15% polyisocyanate and 8% polyester polyol.

[0029] (2) Add 15% aldoxime blocking agent to the prepolymer, and seal the NCO group with the aldoxime blocking agent to form a closed prepolymer, which will decompose carbon dioxide, olefins and primary amines in this step; Amines block free or dissociated NCO groups.

[0030] (3) Add 1% olefin polymerization catalyst, 16% amino acid and 45% water to the blocked prepolymer to form an impregnation solution.

[0031] (3) Immerse the wood in the impregnating liquid, and the impregnating liquid enters the wood under the pressure of 1-10 MPa for 12-24 hours.

[0032] (4) Take out the impregnated wood, then put it into the heating kettle, and heat the impregnated wood for 10-20 hours at a heating temperature of 100-120°C. The NCO group is unblocked, and at the same time, the hydroxyl group in th...

Embodiment 2

[0036] The manufacture method based on oxime end-blocking ceramic wood comprises the following steps:

[0037] (1) Prepare prepolymer, react 10% polyisocyanate and 12% polyester polyol.

[0038] (2) Add 10% aldoxime blocking agent to the prepolymer, and seal the NCO group with the aldoxime blocking agent to form a closed prepolymer, which will decompose carbon dioxide, olefins and primary amines in this step; Amines block free or dissociated NCO groups.

[0039] (3) Add 2% olefin polymerization catalyst, 25% amino acid and 41% water to the blocked prepolymer to form an impregnation solution.

[0040] (3) Immerse the wood in the impregnating liquid, and the impregnating liquid enters the wood under the pressure of 1-10 MPa for 12-24 hours.

[0041] (4) Take out the impregnated wood, then put it into the heating kettle, and heat the impregnated wood for 10-20 hours at a heating temperature of 100-120°C. The NCO group is unblocked, and at the same time, the hydroxyl group in t...

Embodiment 3

[0045] The manufacture method based on oxime end-blocking ceramic wood comprises the following steps:

[0046] (1) To prepare a prepolymer, 11% of polyisocyanate and 9% of polyester polyol were reacted.

[0047] (2) Add 11% aldoxime blocking agent in the prepolymer, seal the NCO group with the aldoxime blocking agent to form a closed prepolymer, and in this step, carbon dioxide, olefins and primary amines will be decomposed; Amines block free or dissociated NCO groups.

[0048] (3) Add 1.5% olefin polymerization catalyst, 17.5% amino acid and 50% water to the blocked prepolymer to form an impregnation solution.

[0049] (3) Immerse the wood in the impregnating liquid, and the impregnating liquid enters the wood under the pressure of 1-10 MPa for 12-24 hours.

[0050] (4) Take out the impregnated wood, then put it into the heating kettle, and heat the impregnated wood for 10-20 hours at a heating temperature of 100-120°C. The NCO group is unblocked, and at the same time, the h...

Abstract

The invention discloses an oxime-based ceramic wood and a manufacturing method thereof. Ceramic wood includes wood, and the gaps in the wood are filled with fillers that combine with wood fibers and form a network structure with wood fibers. It is prepared with water. The manufacturing method is to seal the NCO first, and when the filler enters the wood, the NCO group is unblocked and a chemical reaction occurs. Utilizing the ceramic wood of the present invention and the ceramic wood obtained by the manufacturing method, like ceramics, it is anti-corrosion, waterproof, moth-proof, stable in size, long in service life, and good in performance, so that the wood is not easily deformed and mildewed, and durable at the same time, and the ceramic wood The inner layer is consistent with the outer layer, and will not be different from the inner ceramic wood after the outer layer material is polished off.

Description

technical field [0001] The present invention relates to ceramic wood and its manufacturing method. Especially ceramic wood used in fixtures, decoration materials, building materials, artwork. Background technique [0002] The application of wood is very extensive, such as furniture, decoration materials, building materials, artworks and so on. For long-term use of wood, it is generally necessary to do anti-corrosion and waterproof treatment. During the above-mentioned treatment process, anti-corrosion and waterproof materials are usually used to treat the wood. However, the current anti-corrosion and waterproof materials are only on the surface of the wood, and it is difficult to penetrate into the surface of the wood. In this way, once the anti-corrosion and waterproof material on the surface of the wood is destroyed, the anti-corrosion and waterproof performance of the wood will decrease, and the wood is prone to deformation and mildew. The anti-corrosion wood currently ...
