Problems solved by technology

As far as the common decorative materials in the market are concerned, the release of formaldehyde and other toxic substances basically reaches the E1 or E2 level (the national mandatory standard GB18580-2001 stipulates that the free formaldehyde release reaches the E1 level ≤ 1.5mg / L Decorative materials can be directly used indoors. Decorative materials whose free formaldehyde emission reaches E2 level ≤ 5mg / L must undergo secondary processing before they can be used indoors). Although they meet the requirements of the national standard, there are still harmful substances released.
Moreover, the decoration materials / supplies used in homes or offices, such as furniture, ceilings, screens, cabinets, wallpapers, doors and windows, paints, etc., although the release of harmful substances from each product will meet the national standard requirements, but several decoration materials together Used in the same place and space, the harmful substances released together greatly exceed the national standard, seriously threatening the health of the people

Embodiment 1

[0022] Example 1 Preparation of 10mm poplar plywood

[0023] (1) Raw material processing: Put the poplar wet-medium peeled board into the immersion tank with an ammonia water concentration of 28%, cover and seal it and soak for 36 hours, take it out and dry it in a dryer until the moisture content is 10-16%, and cool it spare.

[0024] (2) Glue adjustment: use 100 parts of starch-modified white latex and 10 parts of polymethyl polyphenylisocyanate two-component glue, measure and stir evenly with a mixer for later use.

[0025] (3) Glue sizing: Pour the adjusted two-component glue into the glue tank of the glue applicator, and adjust the amount of glue applied on one side to 180g / m 2 , sizing poplar mid-board.

[0026] (4) Cold pressing: stack the gluing poplar mid-boards vertically and horizontally (or in the same direction), and send them to a 600-ton cold press, and adjust the pressure to 10kg / cm 2 , pre-pressed for 30 minutes into a slab.

[0027] (5) Hot pressing: put ...

Embodiment 2

[0029] The preparation of embodiment 2 18mm particleboard

[0030] (1) Raw material processing: Put the wet bamboo and wood chips cut by the chipper into the immersion tank with an ammonia concentration of 28%, cover and seal for 30 hours, take it out and dry it in a dryer until the moisture content is 10-16% , cooled and set aside.

[0031] (2) Use 100 parts of starch-modified white latex and 8 parts of polymethyl polyphenylisocyanate two-component glue, measure and stir evenly with a mixer for later use.

[0032] (3) Glue sizing: Pour the adjusted two-component glue into the glue tank of the glue applicator, and adjust the amount of glue applied on one side to 180g / m 2 , sizing poplar mid-board.

[0033] (4) Cold pressing: use the shaving paving machine to carry out directional or non-directional paving and assembly of the glued bamboo / wood chips, and then send the blanks to a 600-ton cold pressing machine, and adjust the pressure to 9kg / cm 2 , pre-pressed for 30 minutes ...

Embodiment 3

[0036] The preparation of embodiment 3 18mm blockboard

[0037](1) Raw material treatment: put the rotary-cut wet middle board and the saw-cut wet wood strips into the soaking pool with an ammonia water concentration of 28%, cover and seal for 48 hours, take them out and dry them in a dryer until the water content is 10-16%, after cooling, use a wood planer or sander to plan or sand the small wooden strips into the required thickness and width, and use a sawing machine to saw both sides of the lower wooden strips for use.

[0038] (2) Glue adjustment: Use 100 parts of starch-modified white latex and 6 parts of polymethyl polyphenylisocyanate two-component glue, measure and stir evenly with a mixer for later use.

[0039] (3) Glue sizing: Pour the adjusted two-component glue into the glue tank of the glue mixer, and adjust the amount of glue applied on one side to 200g / m 2 , Double-sided sizing of small wooden strips.

[0040] (4) Cold pressing: first lay a processed middle p...

Abstract

The present invention is no-aldehyde health decoration material and its production process. The no-aldehyde health decoration board is produced with no-aldehyde adhesive and at least one of bamboo / wood fiber, wood shavings, timber leftover and crop stalk through formaldehyde eliminating treatment. The technological process of producing the no-aldehyde health decoration board includes the steps of material treatment, mixing glue, applying glue, cold pressing to form blank, thermal pressing to settle and post-treatment. The no-aldehyde health decoration board has the advantages of no aldehyde, good moisture-proof and waterproof performance, good secondary machining performance and high stability, and is used in indoor decoration.

Description

technical field [0001] The invention relates to the technical field of decorative materials, in particular to a formaldehyde-free healthy decorative material for interior decoration, and also relates to a preparation method of the decorative material. Background technique [0002] With the improvement of people's living standards, people have put forward higher requirements for the decoration of their living or office spaces, not only requiring beautiful, trendy, natural and concise, but also for the protection of formaldehyde and other harmful substances that directly threaten the health of the people.
