Embodiment Construction

[0006] As shown in the figure, the preparation method of the composite wood-based panel includes the following steps: sending the raw material cotton stalks into a pulverizer for the first pulverization. The width is 5mm, dust is removed by a blower, and the dust content is 3-4%. Put the pulverized cotton stalks into the pulverizer for the second pulverization. The aperture of the pulverizer is less than or equal to 20mm, the water content control rate is 8-11%, and the dust content is 2-3%; Put it into a dryer for drying, the drying temperature is controlled at 150-160°C, and the water content control rate is 2-4%. Send the dried cotton stalks into the mixer for stirring, wherein: the weight ratio of cotton stalks and soybean formaldehyde-free wood adhesive is 0.9:1, and the weight of the added waterproofing agent is 1 / 2 of the weight of the added soybean formaldehyde-free wood adhesive. 12-15%. After stirring, the mixture is sent to be evenly paved, paved into slabs of dif...

Abstract

The invention provides a manufacture method of a compound artificial board which is reasonable and practical in design and low in cost. The compound artificial board is mainly made of cotton stalks, a soybean non-aldehyde wood adhesive and a water-proof agent. The weight ratio of the cotton stalks to the soybean non-aldehyde wood adhesive is 0.9:1. The weight of the added water-proof agent is 12-15% of that of the added soybean non-aldehyde wood adhesive. The technological process of the method mainly comprises the following steps of first smash of raw materials, second smash, drying, stirring, paving, prepressing molding and hot press molding. The compound artificial board manufactured through the method is reasonable and practical in design, saving in resources, reduced in cost, sturdy, durable, capable of improving production efficiency and economic benefit, and suitable for widespread popularization and usage.

Description

Technical field: [0001] The invention relates to the technical field of artificial composite panels, in particular to a preparation method of composite artificial panels. Background technique: [0002] At present, composite wood-based panels have been widely used in various production and manufacturing, and the existing composite panels are mostly made of metal, which not only increases the production cost, but also consumes a large amount of metal raw materials, and the metal composite wood-based panels are used for a long time It is easy to oxidize and deform, and it is also easy to crack when the temperature difference is large. Contents of the invention [0003] The object of the present invention is to provide a method for preparing a composite wood-based panel with reasonable design, practicality and low cost in view of the defects in the prior art. The technical proposal is as follows: it is mainly composed of cotton straw, soybean formaldehyde-free wood adhesive, ...
