Abstract
The present invention relates to a surface treating agent for polypropylene fibers, which is prepared by that non-ionic surfactants A and C are used as main components, and a small amount of alkane B is added. The polypropylene fibers can be uniformly dispersed in water by adding the surface treating agent so as to enhance the affinity with cement; the components A, B and C are environmental-friendly substances with no toxicity or pollution, and are easy to decompose under natural conditions, and the decomposition products are also beneficial to the environment; various components have a synergistic effect, and the effect of various components is better than that of using alone; the polypropylene fibers greatly enhances the dispersibility in water so as to be applicable to the cement after being coated by using the formula; the formula of the treating agent has low cost, easy production and continuous production, and is convenient for industrial manufacture.
Description
Technical field
What the present invention relates to is the synthetic method of a kind of dispersant with high efficiency of using in the polypropylene fibre manufacture process, belongs to chemical field.
Background technology
Cement is one of building industry three big stocks, uses extensively, and consumption is big, have the title of " grain of building industry ".According to the main construction material of predicting this century also will be cement and concrete.Cement Production and research are still very important.The characteristics of cement are to have stronger compression strength, and its shortcoming is the fragility of material, its tension, bending resistance, shock resistance just, and performance such as toughness is poor.In cement matrix,, can improve the tensile strength and the modulus of material disorderly to some staple fibres that distribute.In addition, it is also extremely important to improve the bonding brute force of these fibers and cement.The cement fortifying fibre has metal fibre (stainless steel wire), glass fibre (E glass, A glass, alkali-proof glass), synthetic fiber (polyvinyl, nylon, polypropylene, terylene), potlery tile fiber, carbon fibre, alumina fibre, asbestos fibre etc.It is very good that synthetic fiber such as polypropylene and nylon strengthen concrete shock resistance.The major advantage of polypropylene fibre is good alkali resistance, chemical stability,, high melt point (165 degree centigrade) reactionless with most of chemical substances, and cheap raw material.But, be difficult for being soaked, so and the bad adhesion of cement based by cement mortar because of its hydrophobicity.
In order to improve the interfacial structure between fiber and the matrix, improve the composite performance of the two, need carry out suitable surface treatment to fortifying fibre.So-called surface treatment is exactly to wash the material that is covered with a kind of surface conditioning agent on the reinforcing material surface.This surface conditioning agent comprises sizing agent, and materials such as a series of coupling agents and auxiliary agent, is beneficial to form a good bonding interface between reinforcing material and cement matrix, thereby reaches the purpose that improves the various performances of composite.For polypropylene fibre, its density is littler than water, has certain cohesive force between fiber, and bunchy exists on the water surface.Therefore, need carry out surface conditioning agent to polypropylene fibre and handle, improve its dispersiveness and hydrophily.Otherwise the fiber that those bunchys exist will become the failpoint of humidification.
Surfactant used in the surface conditioning agent also must be selected with fiber affinity bigger.English architecture research institute adds the thin-film network of the polypropylene protofibril of 4% 166.7dtex 51mm in cement products, can make to produce frictional adhesion between polypropylene fibre and cement, thereby the bending resistance of finished product brute force and impact resistance all obviously are better than not adding the goods of reinforcing material.Add a spot of polypropylene fibre in the concrete, can reduce its gas permeability and thermal conductivity, improve its shock-resistant brute force and freexing tolerance.
The component of fiber surface finishing agent commonly used can be two classes: (1) principal component is smooth agent, antistatic additive, emulsifying agent.(2) annexing ingredient: lubricant, soft Liu, obvolvent agent, antioxidant, bleeding agent, PH blender, viscosity improver, stabilizing agent, defoamer, bactericide, preservative agent, the agent of balance debugging mode etc.The conventional fibre surface conditioning agent mainly is made up of 90% above principal component and 10% following supplementary element.
Polypropylene is a hydrophobic fibre, must add surfactant, makes it can be by water-wet.Only contain non-polar group in the polypropylene molecule, it can only combine with dispersion force in surfactant, and this active force is less, so surfactant is not easy to be adsorbed.The moisture percentage of polypropylene under standard state is zero, thereby coefficient of friction is bigger, is easy to generate static, must add excellent lubrication agent and antistatic additive.Polypropylene fibre is met oil and can be expanded, and the cohesive force that expands between the fiber of back reduces, and helps disperseing.Polypropylene fibre friction back is electronegative, so it is strong to the absorption of cationic surfactant, and relatively poor to the absorption of non-ionic surface active agent.But cationic surfactant by polypropylene fibre absorption back lipophilic group outwardly, and the affinity of polypropylene fibre of Chu Liing and water is poor like this, is not easy by water-wet, and polyacrylic density is littler than water, has only 0.9g/cm
3, swim in before the oiling agent on the water surface, must add hydrophilic material it is entered in the water.Polyacrylic surface tension is 30.1Mn/m, and critical surface tension is 32Mn/m, belongs to low-energy surface, and general surfactant reduces seldom the interface interaction power of polypropylene and water, polypropylene fibre wetting not too easy.
Summary of the invention
The objective of the invention is to avoid weak point of the prior art, and a kind of hydrophily that can increase polypropylene fibre is provided, make it be easy to be dispersed in the water, polypropylene fibre surface conditioning agent product that can also Reinforced Polypropylene fiber dispersive property in water.
Can take following technical scheme to realize purpose.
