The invention relates to systems and techniques for manufacturing articles containing cellulosic material, a tackifier, and a binder, and related processes of making and using the cellulosic articles. In particularly exemplary embodiments, the manufactured articles are door skins, sometimes known as door facings, and doors made from the door skins. The article contains a lipophilic cellulosic material, a tackifier, and a binder.

Engineered wood products and binder compositions are provided. In preferred embodiments, the engineered wood products include wax. Methods are also provided for formulating binders for wood comprising unmodified soy flour and synthetic adhesives. The soy-based formulations are prepared by mixing unmodified soy flour with the synthetic adhesive prior to application to the wood or by adding them sequentially to the wood. The present invention provides adequate bonding at reduced cost.

The present invention discloses a method for quick hot-press forming of laminated wood. The method includes: drying a machined small wood material to a moisture content of 5-8 wt %; gluing the dried small wood material, and assembling and laying the dried small wood material to be a square material or a sheet material, where an adhesive for the gluing is a water-soluble adhesive having a solid content of 45-60 wt %; clamping the square material or the sheet material through a three-dimensional metal clamp; sending the clamped square material or sheet material together with the clamp into a microwave heating machine for microwave heating to obtain a formed laminated wood, where the time from the gluing to the entry into the microwave heating machine is controlled to not exceed 15 min. According to the present invention, a glued part that needs to be heated can be heated quickly, precisely and effectively, the gluing strength and production efficiency of the laminated wood can be significantly improved, and the cost of production energy consumption is reduced.

A formulation containing (i) a first component formed from at least one isocyanate and at least one polyether and (ii) a second component including at least one amino resin, wherein the amino resin is the condensation product of an aldehyde and at least one of urea, melamine, benzoguanamine, glycoluril, and acetoguanamine. A process for binding lignocellulosic materials using the formulation is also described.

Binder compositions are described that contain (1) a reducing sugar and (2) a reaction product of a urea compound and an aldehyde-containing compound. A specific example of the binder compositions include dextrose and an imidazolidine compound such as 4,5-dihydroxyimidazolidin-2-one. The binder compositions may be applied to collections of fibers and cured to form a fiber-containing composite, such as fiberglass insulation.
