Abstract
The invention discloses a method for preparing a sheet material gap filler and relates to the field of sheet material production. The method for preparing the sheet material gap filler comprises the steps: (A) adding a protein-containing raw material into water, and stirring uniformly; (B) heating the solution to the temperature of 50-55 DEG C, adjusting the pH value of the solution to 4.5-5.5, and respectively adding cellulase and pectinase for hydrolyzing; (C) adjusting the pH value of the solution to be neutral or alkaline, and then adding neutral or alkaline proteinase for hydrolyzing; and (D) adding hexa-acetamide, calcium carbonate, plant ash, shell powder, glass micro-beads or glass micropowder, gelatin, methyl cellulose or derivatives thereof and an anticorrosive agent, and stirring uniformly, thereby obtaining the sheet material gap filler. The sheet material gap filler prepared by the method has the advantage that the problem that fast-growing wood is required to be subjected to hardening, strengthening and dimensional stabilizing treatment through the traditional phenolic aldehyde, urea formaldehyde or melamine resin dipping treatment can be solved. The sheet material gap filler cannot release formaldehyde during use, is safe and environment-friendly and is low in cost, high in bonding strength and good in water resistance and corrosion resistance.
Description
Technical field
The present invention relates to sheet material production field, especially a kind of preparation method of sheet material gap filler.
Background technology
Current wood working industry has become domestic development speed and has had the manufacturing industry of good prospect, since 2006, China has begun to take shape by utilizing wildwood to be main to utilizing artificial forest to be main transformation, but because the artificial forest woods such as these poplars, China fir, Eucalyptus, pine, paulownia generally have the various natural defects such as material is soft, intensity is low, yielding, apt to rot, easy to change, especially there will be after the drying cracking or nest such as to split at the phenomenon, the use of these timber and goods thereof is under some influence.
In order to solve, the material that these artificial forest woods generally have is soft, intensity is low, the various natural defect such as yielding, apt to rot, easy to change, conventional method carries out phenolic aldehyde, urea aldehyde or melamine resin impregnation process to make soft timber obtain sclerosis, strengthening, size stabilization, but dry run also can cause wood surface cracking or nest to split after impregnation process, reduce the excellent rate of product, and product Formaldehyde emission rate is higher.
Summary of the invention
The invention provides a kind of preparation method of sheet material gap filler, the sheet material gap filler that it is made can solve and require no that traditional phenolic aldehyde, urea aldehyde or melamine resin impregnation process are hardened to fast growing wood, strengthened, the problem of size stabilization.
In order to solve the problem, the technical solution adopted in the present invention is: the preparation method of this sheet material gap filler comprises the following steps:
A, joining 8 ~ 10 weight portions in the water of 30 ~ 50 weight portions containing protein raw material, stir and obtain protein solution;
B, steps A gained protein solution is heated to 50 ~ 55 DEG C, adds inorganic or organic acid and regulate PH to 4.5 ~ 5.5, then add cellulase and the pectase of 0.1 ~ 0.5 weight portion respectively, be hydrolyzed 30 ~ 120 minutes;
C, add one or several mixed liquor of NaOH, potassium hydroxide or ammoniacal liquor to step B gained solution, regulate PH be neutrality or alkaline, then add the neutrality of 0.1 ~ 0.5 weight portion or alkali protease is hydrolyzed 30 ~ 120 minutes;
The anticorrisive agent of the calcium carbonate of D, the acetamide in the sixth of the twelve Earthly Branches adding 1 ~ 3 weight portion to step C gained solution, 1 ~ 5 weight portion, the plant ash of 1 ~ 5 weight portion, the oyster shell whiting of 1 ~ 5 weight portion, the glass microballoon of 1 ~ 5 weight portion or glass micro mist, the gelatin of 1 ~ 5 weight portion, the methylcellulose or derivatives thereof of 1 ~ 5 weight portion and 1 ~ 3 weight portion, stirs and get final product;
Described proteinaceous raw material is the mixture of one or more of corn protein powder, soyabean protein powder, animal globulin powder;
Described anticorrisive agent is the mixture of one or more of sorbic acid, potassium sorbate, phytic acid, methyl p-hydroxybenzoate, ethyl-para-hydroxybenzoate, propylparaben, ethoxyquin, dehydroactic acid, benzoic acid, Sodium Benzoate, sodium propionate, calcium propionate, sodium hydrogensulfite or sodium sulfite.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, the acetamide in the sixth of the twelve Earthly Branches that the present invention adopts has higher reactivity, normal temperature solidified, glued membrane is tough and tensile, shock-resistant, flexibility is good, oil resistant is wear-resisting, low temperature resistant, the sheet material gap filler produced can directly spread upon on plank, normal temperature natural coagulation, effectively can fill up cracking that soft fast growing wood drying occurs afterwards or nest splits, it can be made again to obtain sclerosis, strengthening and size stabilization.
2, not Diazolidinyl Urea in use procedure of the present invention, safety and environmental protection.
3, raw material sources of the present invention are wide, and cost is low.
4, water resistant of the present invention, antiseptic property are good.
