Abstract
The invention discloses a water glue powder for the wood industry, and a production method for the water glue powder. The water glue powder can completely replace glue and a filling material which are used in a plywood production process. The water glue powder is a solid powder, and can be directly used after being uniformly mixed with water of which the weight is twice of that of the water glue powder, without adding other filling materials; the water glue powder is low in manufacturing cost, environment-friendly, long in shelf life and easy to transport, and is prepared from the following components in parts by weight: 8-20 parts of polyvinyl acetate, 20-30 parts of starch, 0.01-0.05 part of an antioxidant, 2-5 parts of stearic acid, 5 parts of melamine, 10 parts of polyvinyl alcohol, 15-25 parts of oxidized starch, 0.5 part of borax and 7-15 parts of attapulgite.
Description
Technical field
The present invention relates to sheet fabrication glue class field, be specifically related to a kind of wooden industry glue powder and production method thereof.
Background technology
Need in current plywood production technology process to add 10-40% industry flour as filler with urea-formaldehyde glue or phenolic glue, be applied in after blending on veneer and carry out precompressed and heat pressing process again.The glue that domestic nearly all glued board producer uses, it is all the liquid glue bought in local glue producer, price is high, transport trouble, and the quality guaranteed period is short, use complexity, in use need to add filler to be in harmonious proportion, and free formaldehyde release is very high, quite not environmentally, make work under bad environment, sheet material environmental protection difficulty is up to standard.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of wooden industry glue powder, the glue and filler that use in plywood production process can be substituted completely, the present invention is solid, powdery thing, directly be in harmonious proportion with the water of twice during use and evenly use, without the need to adding other filler, production cost is low, environmental protection, long quality-guarantee period, convenient transportation.
The present invention is achieved through the following technical solutions:
A kind of wooden industry glue powder, the component proportion gained by following weight part: polyvinyl acetate (PVA) 8-20 part, starch 20-30 part, antioxidant 0.01-0.05 part, stearic acid 2-5 part, trimeric cyanamide 5 parts, polyvinyl alcohol 10 parts, Sumstar 190 15-25 part, borax 0.5 part, attapulgite 7-15 part.
The further improvement project of the present invention is, described starch is W-Gum or tapioca (flour).
Present invention also offers a kind of production method manufacturing above-mentioned wooden industry glue powder, the steps include:
(1) heat to 110-120 degree by polyvinyl acetate (PVA), starch, kneading 20-40 minute, is cooled to less than 100 degree;
(2) add stearic acid kneading 5-10 minute, then add antioxidant kneading 5 minutes, discharging cools, and is crushed to more than 100 orders.
(3) add trimeric cyanamide, polyvinyl alcohol, Sumstar 190, borax, attapulgite, stir with mixing machine.
The present invention compared with prior art, has following obvious advantage:
1: cost reduces, use product of the present invention can save 40% cost for man of plywood factory at glue and surface side filler completely.
2: convenient transportation, product of the present invention is solid, powdery material, than traditional liquid glue, is more easy to transport, reduces trucking costs.
3: long quality-guarantee period, the traditional liquid glue quality guaranteed period is very short, and substantially about a week, and shelf life of products of the present invention reaches 180 days, with the obvious advantage.
4: easy to use, product ready access upon use of the present invention, is in harmonious proportion can uses with water, without the need to adding other filler, convenient and swift.
5: environmental protection, product of the present invention is not completely containing formaldehyde, and traditional liquid glue all cannot accomplish zero formaldehyde, therefore uses product of the present invention can respond the call of national green environmental protection, Optimization Work environment, improves workman's job enthusiasm.
Embodiment
In order to make the object, technical solutions and advantages of the present invention clearly understand, below in conjunction with embodiment, the present invention is described in further details.At this, exemplary embodiment of the present invention and illustrate for explaining the present invention, but not as to invent restriction.
Embodiment 1
A kind of wooden industry glue powder, the component proportion gained by following weight part: polyvinyl acetate (PVA) 8 parts, W-Gum 20 parts, antioxidant 0.01 part, stearic acid 5 parts, trimeric cyanamide 5 parts, polyvinyl alcohol 10 parts, Sumstar 190 15 parts, borax 0.5 part, attapulgite 7 parts.
Its production stage is:
(1) heat to 110-120 degree by polyvinyl acetate (PVA), W-Gum, kneading 20-40 minute, is cooled to less than 100 degree;
(2) add stearic acid kneading 5-10 minute, then add antioxidant kneading 5 minutes, discharging cools, and is crushed to more than 100 orders.
(3) add trimeric cyanamide, polyvinyl alcohol, Sumstar 190, borax, attapulgite, stir with mixing machine.
Embodiment 2
The present invention is by the component proportion gained of following weight part: polyvinyl acetate (PVA) 15 parts, tapioca (flour) 25 parts, antioxidant 0.05 part, stearic acid 2 parts, trimeric cyanamide 5 parts, polyvinyl alcohol 10 parts, Sumstar 190 25 parts, borax 0.5 part, attapulgite 10 parts.
Its production stage is as embodiment 1.
Embodiment 3
Component proportion gained by following weight part: polyvinyl acetate (PVA) 20 parts, tapioca (flour) 30 parts, antioxidant 0.03 part, stearic acid 5 parts, trimeric cyanamide 5 parts, polyvinyl alcohol 10 parts, Sumstar 190 20 parts, borax 0.5 part, attapulgite 7 parts.
Its production stage is as embodiment 1.
Its production stage is as embodiment 1.
Now adopt above-described embodiment glue powder and traditional glue blended flour, the glued board (glued board type: II class, specification mm:500*500*10, every routine sample size 3 pieces) of making makes experiment Data Comparison:
| Stopping composition | Cost (first ton) | Bonding strength MPa | Poach does not come unglued time h |
| Tradition glue blended flour | 3046 | 0.83-1.17 | 3 |
| Embodiment 1 | 1920 | 0.87-1.21 | 3.2 |
