Abstract
The present invention relates to a shaving board without formaldehyde and a production method thereof. The present invention is characterized in that the raw materials comprise wooded dry shavings, polymetyhlene polyphenyl isocyanate and an isocyanate water soluble adhesive. The present invention has the advantages of reasonable and fine ingredient and simple and scientific production method. A shaving board produced by the present invention does not contain poisonous and harmful substances such as free formaldehyde, etc. The formaldehyde emission is 0 mg/100g; simultaneously, the water resisting property and the bonding strength of the shaving board are greatly improved; the present invention is an ideal shaving board for interior decoration and exterior decoration.
Description
One, technical field
The present invention relates to a kind of particieboard and production method thereof, particularly a kind of zero-formaldehyde particleboard and working method.
Two, background technology
The present indoor category-A environment-friendly type shaving board of E1 level low toxicity, though free formaldehyde release has wherein reached and has been lower than domestic and world's like product standard, but wherein still contain the existence of harmful substances such as formaldehyde, to exist latent threat in indoor use to health; Can bring out diseases such as multiple cancer, leukaemia in environment inhabitation or activity that formaldehyde is arranged for a long time, this is that existing particieboard uses in indoor deficiency.
Three, summary of the invention
The objective of the invention is to invent a kind of zero-formaldehyde particleboard and working method, this particieboard will no longer contain poisonous and harmful substances such as free formaldehyde, burst size of methanal is 0mg/100g, simultaneously its resistance to water and glue-joint strength are greatly improved, in order to overcome the deficiency of existing particieboard and production method thereof.
Purpose of the present invention can realize by following embodiment: the weight portion of raw material of the present invention includes the wooden dried wood shavings of 680-720 part, many benzene of polymethylene polyisocyanates of 25-30 part is the isocyanates water soluble adhesive of PAPI and 65-70 part, wherein carry out in the hot-forming process at described particieboard, utilize moisture content and many benzene of polymethylene polyisocyanates in the isocyanates water soluble adhesive under 170 ℃ hot conditions, to react curing, thereby make many benzene of polymethylene polyisocyanates some wooden dried wood shavings molding bondeds.
The weight portion of raw material of the present invention includes the isocyanates water soluble adhesive that 680 parts wooden dried wood shavings, many benzene of polymethylene polyisocyanates of 25 parts are PAPI and 65 parts.
The weight portion of raw material of the present invention includes the isocyanates water soluble adhesive that 700 parts wooden dried wood shavings, many benzene of polymethylene polyisocyanates of 27 parts are PAPI and 67 parts.
The weight portion of raw material of the present invention includes the isocyanates water soluble adhesive that 720 parts wooden dried wood shavings, many benzene of polymethylene polyisocyanates of 30 parts are PAPI and 70 parts.
Life side of the present invention method is: the making of A, wooden dried wood shavings: chip, flaking, screening, drying, to screen, make its weight portion be 680-720 part, feeding warehouse; B, weight portion are that the polymethylene polyisocyanates of 25-30 part be PAPI with weight portion is that the isocyanates water soluble adhesive of 65-70 part mixes the miscible glue that becomes; C, above-mentioned glue is sprayed to the wood particle surface, and be penetrated into wood particle inside, form the adhesive overlay film on the wood particle surface; D, mat formation and hot pressing, in hot-forming process, utilize moisture content and many benzene of polymethylene polyisocyanates in the isocyanates water soluble adhesive under 170 ℃ hot conditions, to react curing, thereby make many benzene of polymethylene polyisocyanates with some wood particle molding bondeds, pass through sawing, sanding, make particieboard; E, employing spray to presed-steel plate and wood particle shaping slab surface formation barrier film with remover, prevent that many benzene of polymethylene polyisocyanates from bonding together at following wood particle of hot conditions and presed-steel plate.
Advantage of the present invention is: 1, do not contain the formaldehyde material; 2, resistance to water is strong, traditional E1 level shaving board is pressed the thickness swelling rate check in the GB1T-92 standard, be 5-8% generally speaking, and particleboard with zero-formaldehyde emission is through detecting with quadrat method, thickness swelling rate only is 0.8-1% after 8 hours, soaking the back thickness swelling rate in 24 hours only is 8-9.5%, and this is that traditional E1 level moisture resistant chipboard is all inaccessiable; 3, glue-joint strength is good, product is not yielding in storing and using, because meeting water under hot conditions, many benzene of polymethylene polyisocyanates solidifies rapidly, there is not the adhesive hydrolysis when forming cooling behind the product, so this product one-shot forming intensity is better, use to store distortion not occur; 4, needn't use waterproofing agent, curing agent etc. to add assistant agent, simplify product manufacture aborning.
Four, description of drawings
The present invention is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is technological process of production figure of the present invention
Five, the specific embodiment
Be three embodiment of parts by weight of raw materials of the present invention below:
1, the weight portion of raw material of the present invention includes the isocyanates water soluble adhesive that 680 parts wooden dried wood shavings, many benzene of polymethylene polyisocyanates of 25 parts are PAPI and 65 parts.
2, the weight portion of raw material of the present invention includes the isocyanates water soluble adhesive that 700 parts wooden dried wood shavings, many benzene of polymethylene polyisocyanates of 27 parts are PAPI and 67 parts.
3, the weight portion of raw material of the present invention includes the isocyanates water soluble adhesive that 720 parts wooden dried wood shavings, many benzene of polymethylene polyisocyanates of 30 parts are PAPI and 70 parts.
The production method of above-mentioned three embodiment is with the production method of summary of the invention part.
