Background technology
Along with the development of industrial civilization, people strengthen gradually to the environmental consciousness of industrial products, and environmental requirement also further improves thereupon.At present, the main making material of sponge product on the market is polyurethane and PVA.This series products in process of production, a large amount of with an organic solvent and the harmful chemical residual in the finished product also extremely serious, be difficult under field conditions (factors) decomposing contaminated environment after it is discarded.Though traditional wooden sponge environmental protection, technological process complexity, topmost shortcoming are that sponge intensity is low, are not durable.Therefore, design one cover technological process make high-strength durable, the long service life of the sponge produced and simple and practical, be convenient to operation, become the task of top priority.
Summary of the invention
In order to overcome the prior art deficiency, the invention provides a kind of production technology of enhanced wood fiber sponge, can produce the wood fibre sponge of intensity index excellence.
The technical solution adopted for the present invention to solve the technical problems is: design a kind of production technology of enhanced wood fiber sponge, it is characterized in that raw-material set-up procedure is as follows:
(1) uses the aqueous slkali soaking wood pulp;
(2) wood pulp is deposited degreasing: the wood pulp that will soak is deposited degreasing, up to making it the fully fluffy alpha-cellulose that becomes;
(3) alpha-cellulose sulfonating reaction: add carbon disulfide in alpha-cellulose, making it sulfonation becomes gel;
(4) gel and aqueous slkali are fully mixed, make it to become the alpha-cellulose viscose;
(5) cotton is placed on soak degreasing in the aqueous slkali, adds nitra-amine then and fully mix to make softening cotton fiber;
(6) add sal glauberi, cotton fiber and mill base in the alpha-cellulose viscose, said mixture is stirred can obtain raw material;
Production process is carried out as follows successively:
(1) raw material is put into digester and added the water boiling, make the wood fibre sponge after sal glauberi is fully dissolved.
(2) the wood fibre sponge of making is cleaned with weak acid solution;
(3) the wood fibre sponge is used liquor natrii hypochloritis's rinsing;
(4) will clean with dodium thiosulfate solution with the wood fibre sponge of liquor natrii hypochloritis's rinsing, make enhanced wood fiber sponge.
The production technology of a kind of enhanced wood fiber sponge of the present invention is characterized in that the soak time of wood pulp in aqueous slkali is 30～50 minutes, and temperature is 35～40 ℃, and aqueous slkali is that mass concentration is 40%～50% sodium hydroxide solution.The time that wood pulp is deposited degreasing is 48 hours.The time of alpha-cellulose sulfonating reaction is 2～3 hours, and temperature is 20～30 ℃.With gel and mass concentration is that 30%～55% sodium hydroxide solution mixes, and makes it to become the alpha-cellulose viscose.It is 40%～65% sodium hydroxide solution degreasing that cotton is put into mass concentration.The time that raw material are put into the digester boiling is 3～5 hours.
The beneficial effect that the present invention had is:
1. add cotton fiber in the wood fibre sponge that the present invention produces, the fibre length of cotton fiber is long than wood fibre, sneaks into the intensity that can strengthen the sponge manufactured goods in the wood fibre, increases durability and service life.
2. cotton fiber also has through the aqueous slkali degreasing in the sponge, and hydrophily is good, and is not easy to produce allergic reaction; Cotton fiber is handled softening by nitra-amine, make the sponge quality fine and smooth soft.
3. the wood fibre sponge is by after liquor natrii hypochloritis's rinsing, and it is more fresh and alive beautiful to make mill base in the sponge present color; Sponge cleaning with output behind the dodium thiosulfate solution dechlorination is tasteless, is suitable for multiple uses such as industrial production and civilian cleaning.
4. this technological process of production is simple, and is easy to operate, need not large-scale special machinery, and the operation cost is low, the suitability for industrialized volume production.
