Wet material adhesive technology

I. Product Overview:
Beijing Huaxia Keyuan Technology Development Center (more projects are available at http:// ) The Adhesive Expert Group developed the wet material adhesive technology, which is a one-component adhesive product for wet wood bonding and slicing, and has become a wet material for slicing. One of the most stable adhesive products recognized by customers. It is mainly applied to the bonding of materials without drying or with high moisture content; it is also a special adhesive for the current market for thinly sliced ​​wood. Mainly used in the bonding of high-moisture wood, the moisture content is generally more than 30%. At this time, the wet material can be fingered or spliced ​​into large square materials with wet material glue, and can be sliced ​​after curing. Process requirements for thin wood. To a great extent, the utilization rate of wood is improved, and the quality of the wood shavings is fully improved, especially for high density materials. The product is a single-component moisture curing adhesive and the operation process is simple. For non-dried wood, or materials with high moisture content, the bonding effect is better. The product is non-toxic, odorless and has a wide range of uses. It has a high bonding strength, and is excellent in toughness, water resistance, and moisture and heat aging resistance. Both room temperature and heating can be cured, excellent heat resistance after curing.
II. Application areas:
1. Suitable for splicing and finger joints of veneer, sliced ​​veneer, and various shapes of veneer;

2. The product features superior performance, convenient construction, foaming of the adhesive layer after curing, insolubility, resistance to high and low temperatures, etc. Its overall performance is better than that of the same type of one-component and two-component styrofoam. The glue is not only used for bonding various shapes of wet wood, but also used for manufacturing fireproof doors , security doors , split doors, various composite plates in refrigeration equipment and various fireproof and heat preservation materials (rockwool, ceramic wool, super Bonding of fine glass wool, polystyrene foam, etc. can also be used for metal- to-metal bonding.

Three. Product advantages:
1. Break the limitations of traditional white latex and puzzle glue that can only stick to dry wood, wet wood glue has the characteristics of bonding wet wood;
2. Wide application of wood moisture content, more than 30% of wood with high water content is more excellent;
3, the application of wet wood glue, you can re-paste the fragmented wood and then reuse, greatly improving the timber out of the wood, thus fundamentally saving the wood, reducing production costs;
4, the application of wet wood glue in the production process, can make the wood flake in the conditions of greater humidity, thereby improving the quality of the flake, to avoid the dry planing barbs, cracks, etc.;
5, less sizing and easy coating, the process is more convenient;
6, non-toxic after curing, with superior adhesive strength and outstanding water resistance;
7, excellent flexibility, easy to cut does not damage the tool;
8, after high-temperature cooking softening wood, the joint can still maintain a high wet strength;
9. Excellent adhesion to high hardness and high density wood.
Four. Technical indicators:
Appearance tan viscous liquid
Solid content >60--90%
Viscosity 200-5000mPa.s
Operating standard
The moisture content should be controlled at more than 30%. The greater the humidity, the better the effect. The operating environment temperature should be above 15°C, otherwise the curing time should be extended. The substrate surface is smooth and clean without impurities. The stitching time is adjustable from 1-4 hours.

V. Production conditions:
The main equipment for producing this product: reactor. The product cost is about 11--12 yuan per kilogram, and the market price is about 25--35 yuan. Needs workers 2 --- 3 people, plant 50-100 square meters. The raw materials used to produce this product are easily available throughout the country, and there is no special requirement for the cultural level of production personnel. On-site training, learned so far, the product has the characteristics of low cost, simple process, long storage time, stable quality and so on.
Six. Transfer methods and costs:
The full set of technology transfer of this project. The training fee is 30,000 yuan.
