Description

One kind enhancing flexible method of modifying of brucite fiber
Technical field
The invention belongs to inorfil field of papermaking, the more particularly to a kind of flexible modification side of enhancing brucite fiber Method.
Background technology
Paper and its paper products are necessitys indispensable in people's daily life, and paper industry is in global economy and civilization In play key player, the output value accounts for the 2.5% of the world industry gross output value.Timber is the primary raw material of paper industry, accounts for papermaking original More than the 93% of material, with the fast development of paper-making industry, causes disafforestation on a large scale, whole world area of woods is fallen sharply, waste Desertization is aggravated, while also brings serious pollution environment, influences human health.The increase of current domestic paper production total amount and make The shortage of paper material, us are forced actively to find the substitute of cheap paper pulp fiber.Mineral fibres is different from string, system Standby process will not cause environmental pollution, and also different from conventional filler calcium carbonate, talcum powder, it is between short fiber of plant and tradition A kind of novel papermaking material between filler, therefore, mineral fibres is used for paper industry, substantial amounts of string can be saved, This to reduce papermaking cost, conserve forests and ecological environment, reduce paper-making pollution have important meaning.
Brucite fiber is the fibrous variant of shepardite mineral, and main chemical compositions are Mg (OH) 2, its fiber is pure white, Legibility beam, interlayer are connected by weak hydrogen-oxygen key, are easily formed hydrogen bond with hydrone, can be disperseed well in water slurry, are had excellent Good mechanical property, alkali resistance and environmental safety, interleaving effect can be produced with string, form string and ore deposit
The network structure of thing composite fibre, filler can be used as to substitute Activities of Some Plants fiber and carry out copy paper, reduction is produced into This, reduces environmental pollution.Although brucite fiber can be combined with string, because fiber weakness is big, rigidity is strong, fiber It is short, it is easier to be fractured into small section fibre in pulping process, and fiber surface is almost mutual without that can produce with plant fibre surface The group of effect, adhesion is strong between adhesion can not show a candle to string, as the increase of addition can cause paper strength big Amplitude declines.
Therefore, need to be modified brucite fiber processing in paper-making process, it is fine with plant to improve brucite fiber The compatibility of dimension, mitigate it to adverse effect caused by paper making process and paper properties, change at present on brucite fiber Property processing research it is less, minority is using conventional surfactants or coupling agent surface coating modification, as Chinese patent discloses Number CN104817797A discloses a kind of stone paper composites of modified shepardite and preparation method thereof, the composite by Modified shepardite powder, polyvinyl resin or polyvinyl alcohol or water-soluble resin VAE emulsions, auxiliary agent, antioxidant and anti-corrosion Agent combines, and described modification shepardite is nonionic（Isooctyl phenol polyethoxylate）Modified brucite powder, anion（Firmly Resin acid, odium stearate）Modified brucite powder, coupling agent（Gamma-aminopropyl-triethoxy-silane）One kind in modified brucite powder.
In summary, brucite fiber can be improved in paper-making process by surfactant or coupling agent coating modification Retention, improve the compatibility of brucite fiber and string to a certain extent, but still unresolved brucite fiber is crisp Property big, the problem of rigidity is strong, easy fracture, therefore paper properties particularly intensity index can be produced with the increase of addition A certain degree of adverse effect dimension, simultaneously because the active group on brucite fiber surface is seldom, and the combination of modifying agent is limited, Reduce the utilization rate of modifying agent.
The content of the invention
The present invention is in view of the above-mentioned problems, propose a kind of enhancing flexible method of modifying of brucite fiber.This method be by Anion surfactant is added after brucite fiber decentralized processing and carries out surface-active-treatment, brucite fiber surface is presented Elecrtonegativity, using the modified brucite fiber in surface as core, in the presence of initiator by polyaminoester emulsion and flexible sun from Sub- activator is aggregated in the surface of modified brucite fiber, makes one layer of uniform flexible polymer of brucite fiber Surface coating, Strengthen the pliability of brucite fiber, avoid in paper-making process mechanical force to brucite fiber structural damage；Increase water simultaneously The active group of magnesite fiber surface, improve the adhesion of brucite fiber and string.This hair brucite fiber has Higher pliability and dispersiveness, the pliability of paper can be significantly improved during for papermaking, improve brucite fiber in papermaking Addition in journey.
