Abstract
A kind of method of producing protecting paper of gypsum board and products thereof is the special paperboard that is used for the building paper surface gypsum board.The characteristics of its production method are that employing reed reed chemical pulp is a main raw material, are equipped with cotton pulp and recycled newsprint pulp, use common cylinder mould machine production.Produce mask paper with the self-control cotton pulp, realize production domesticization, its every index reaches the level of external mask paper, has good economic benefit and social benefit.
Description
The present invention relates to a kind of method of producing protecting paper of gypsum board and products thereof, belong to the paper industry category.
As everyone knows, Thistle board is to be core with the gypsum, a kind of New Building Materials of the special mask paper of outsourcing.Owing to have sound insulation, characteristics such as heat insulation, fire-resistant, extensively be used as the body of wall and the ceiling material of building construction.
Mask paper is the main material that is used to make the building paper surface gypsum board, relies on the bonding of modified starch, and itself and gypsum core are bonded together securely, and gypsum core is played protection and humidification, and the performance of mask paper is directly connected to the intensity and the outward appearance of gypsum sheet material.
Protecting paper of gypsum board belongs to the New Building Materials cardboard in China, but it is existing abroad historical, the U.S. just began to produce protecting paper of gypsum board greatly before 80 years, also there is the production protecting paper of gypsum board history in year surplus in the of 40 in states such as West Germany, Sweden, Finland, and it is the fastest in the world country that Japan produces its development speed of protecting paper of gypsum board.According to China New Building Material Co.'s in May, 1985 and December in 1987 going to the introduction of Japan expedition protecting paper of gypsum board data twice, Japan's protecting paper of gypsum board output in 1985 is 150,000 tons, then is increased to 210,000 tons, and occupies first place in the world in 1986.The equipment that American-European and Japan produces mask paper has the advanced level eighties.The paper machine that uses as the Marie-Therese Davidson paper plant of Britain is a paper machine of the laminated network.Though the paper machine that Sweden Ying Lande paper plant uses is a common garden net paper machine, the automatic instrument(s) advanced person.Japan produces mask paper and all adopts super forming paper machine, and with the electronics computer control quantitative and moisture content.The raw material mix that these countries produce the mask paper is basic identical, all be to be raw material with old newsprint, papers for books and periodicals, corrugation case waste paper, but these raw materials all is whole wood pulp waste paper.The protecting paper of gypsum board of being produced all can satisfy the gypsum board manufacture technological requirement.
By the means of production of relevant protecting paper of gypsum board with to external sample analysis, the protecting paper of gypsum board of states such as West Germany, Japan, the U.S., Sweden all is to produce with 100% wood pulp waste paper.
6 of the existing gypsum board production lines of China, domestic no manufacturer production mask paper of past all relies on import mask paper to satisfy gypsum board manufacture.For solving the needed mask paper of national plasterboard factory, began to build Hunan Construction Material Paper Factory's protecting paper of gypsum board production line in 1980.Because China's timber resources lacks, as producing mask paper with whole wood pulp waste paper, not only it costs an arm and a leg, and has also limited production scale, and the production of then homemade mask paper will be impossible.But China is used for other abundant raw material of papermaking, as reed, waste cotton, straw etc.
The object of the present invention is to provide a kind of is main raw material with reed reed, is equipped with cotton pulp and recycled newsprint pulp and produces method of protecting paper of gypsum board and products thereof, and quality reaches the every index request of external like product.
Main production process of the present invention is seen accompanying drawing 1.
The present invention finishes production by following technical process:
1, slurrying.
A, raw material: Dongting Lake reed reed, stored screening dedusting after cutting into slices about 1 year.
B, cooking schedule and quality requirement
Boiling method: soda processes or sulfate process
Alkali charge 14～20%
Liquor ratio 1: 2.8
Manganese value 8～13
The residual alkali 7～15g/L of black liquor
Polyoses content＜22%
C, wash sieve:
With vacuum pulp washing machine washing, make paper pulp and black liquid separation, remove thick slag silt particle and make qualified natural color pulp through selected.
D, bleaching:
True qualities reed reed pulp after washing sieve is further removed lignin and other coloring matters, make bleached pulp.
Bleaching process and quality requirement:
Bleaching concentration 18～30g/L
Bleachability 2～5%
Whiteness 55～60%
PH value＞7
Chloride content＜80mg/L
E, Waste Paper Handling:
Waste paper is screened, purifies, washes sieve, operation such as concentrates and make qualified secondary stock through size degradation, make core slurry prime cement and use.Send slurry concentration more than 3%.
2, pull an oar, join slurry:
The beating degree of A, slurry: starch adhesive 22-40 ° SR
22-40 ° of SR of core slurry
25～45 ° of SR of prime cement
The pH value of B, slurry: starch adhesive 4.7～5.5
Core slurry 5.0～6.0
Prime cement 5.0～6.0
The proportioning of C, slurry: cotton pulp 25～35% in the starch adhesive
Reed reed pulp 65～75%
Reed reed pulp 65～75% in the core slurry
Secondary stock 25～35%
Prime cement is all used secondary stock.
D, applying glue:
Use gum rosin.Concentration 15～25g/L
Each layer slurry resin added starch adhesive 0.3～2.5g/L
Core slurry 0.3～2.5g/L
Prime cement 0.3～2.5g/L
Aluminum sulfate concentration about 15%, its consumption are 3～4 times of gum rosin amount, are as the criterion with the control pH value.
3, copy paper:
With the slurry that making beating makes, through the garden net forming, squeezing, dry, press polish are batched to finished product.
A, product quality of the present invention:
Quantitative 290 ± 5g/m
2
Vertical 180～the 210N of tensile strength
Laterally more than the 60N
The surface absorbs weight positive and negative 15～25g/m

The present invention compared with the prior art has obvious superiority:
1, adopts reed reed that China oneself has, waste cotton etc. to be main raw material, need transform former paper equipment hardly, in technological process, improve a little, just can produce mask paper, production cost is reduced greatly.
2, protecting paper of gypsum board of the present invention can change the passive situation of the long-term dependence on import of mask paper, can be country every year and saves a large amount of foreign exchanges, helps the development of China's building material.
3, protecting paper of gypsum board of the present invention has and can not break when satisfying plasterboard making sheet and the bending strength of plasterboard finished product, there is certain gas permeability to make plasterboard in moulding and dry run, evaporate moisture content in the core, has good adhesive property simultaneously, not delamination, do not crease, the quantitative difference of full width is little, and humidity shape is little, advantage such as associativity is good between ply of board.
