Airbag-loading potable weak and soft interlayer direct shear apparatus

The invention provides a simple, accurate and field airbag-loading potable soft and weak interlayer direct shear apparatus. In the direct shear apparatus, airbag loading is adopted to apply a normal force, and a piston system arranged on the upper part of a reaction frame can guarantee the verticality and application uniformity of the normal force when a sample produces shearing displacement; and a ball screw system applies a tangential force and linear guides under a sample seat can guarantee the horizontality of the application direction of the shearing force and the continuity and smoothness of the tangential force. A normal force applying system avoids bearing load, and airbag pressurization is accomplished by a potable pressurizing device and is high in precision, simple and easy to implement. A tangential force applying system uses a screw handle to apply force and the force application is steady and highly operable. Both the normal force applying system and the tangential force applying system are fixed, small in volume, high in reliability and convenient in on-site test. The test device can perform the quick shearing of field soft and weak interlayer and consolidated drained quick and slow shear tests and is simple, precise and high in operability.

EVA (Ethylene-Vinyl Acetate) composite emulsion type low temperature-resistant and environmentally-friendly all-purpose adhesive and preparation method thereof

The invention discloses an EVA (Ethylene-Vinyl Acetate) composite emulsion type low temperature-resistant and environmentally-friendly all-purpose adhesive and a preparation method thereof, belonging to the field of water-based adhesives. The invention adopts the technical scheme that an EVA emulsion is modified by utilizing a rosin tackifying resin emulsion and a polyurethane emulsion together to prepare the EVA emulsion all-purpose adhesive. The all-purpose adhesive comprises the following components in parts by weight: 65-80 parts of EVA emulsion, 5-15 parts of rosin tackifying resin emulsion, 5-15 parts of polyurethane emulsion and the balance of auxiliary agent, wherein the auxiliary agent comprises an antifreeze agent, a plasticizer, a mildew-proof agent, a wetting agent and a pH regulator. When making, the preparation method comprises the following steps of: adding the EVA emulsion to a dispersion kettle with a stirrer, and uniformly stirring; adding the polyurethane emulsion, and stirring and mixing for 1.0-1.5h; then adding the rosin tackifying resin emulsion, the plasticizer of dibutyl phthalate, the antifreeze agent of glycol, the mildew-proof agent of Kathon and the wetting agent, and stirring and uniformly mixing; adding the pH regulator, such as ammonia water or triethylamine to regulate pH value to be 4.5-5.5, and filtering and discharging. The obtained all-purpose adhesive has indexes which reach or exceed common white latexes, convenient use and wide applicability, and can be widely used for architectural decoration, furniture making, cases, and the like and used at normal temperature but also at the low temperature from 5 DEG C to 5 DEG C below zero.
