Technical Field

The invention belongs to the technical field of asphalt waterproof coiled material heat resistance testing, and particularly relates to a method for testing heat resistance of an asphalt waterproof coiled material.

Background

The asphalt waterproof coiled material is a traditional waterproof coiled material, has low cost, but has low tensile strength and elongation, poor temperature stability, high temperature and easy flowing and low temperature brittle fracture; the aging resistance is poor, the service life is short, and the waterproof roll belongs to a low-grade waterproof roll. The asphalt waterproof coiled material can be divided into a filled coiled material and a non-filled coiled material, and the filled coiled material is a coiled material which is made by impregnating petroleum asphalt with filling materials such as thick paper or glass wool cloth, asbestos cloth, cotton linen and the like; asbestos, rubber powder, etc. are mixed into asphalt material, and the rolled material is called rolled coiled material, i.e. tubeless coiled material. The waterproof coiled material can resist external rainwater, underground water leakage and the like, plays a vital role in the whole project, and is one of important varieties in waterproof materials for building projects.

The heat resistance of the asphalt waterproof coiled material characterizes the performance of the waterproof coiled material after being heated. The heat resistance of asphalt waterproofing rolls with reinforced layers is specifically specified in the asphalt waterproofing roll heat resistance (GB/T328.11-2007) of section 11 of the test method for building waterproofing rolls, and two test methods are given. The principle of the method A is as follows: the test pieces cut from the test piece were suspended vertically in an oven at a predetermined temperature, and the displacement of the coating layers on both sides of the test piece with respect to the carcass was measured after a predetermined time, and the average displacement exceeding 2.0mm was judged to be unacceptable, and the heat resistance limit was determined by interpolating the results at the two temperatures.

The method A comprises the steps of placing marking devices at two sides of a test piece, inserting bolts to position and center the test piece, vertically drawing a line (the width is about 0.5mm) along a straight edge in the whole width direction of the surface of the test piece by using a marking pen, and horizontally placing the test piece during operation; the method A discloses a marking method, but the marking lines are drawn by manual operation for the two times of marking, and when the marking lines are drawn by manual operation, the experimental error is possibly large to influence the final heat resistance test result, the marking lines are not necessarily drawn at the same place by manual operation, and certain position deviation exists between the two lines, so that the final average displacement of the two coating layers of the test piece relative to the matrix is more than 2.0mm, the test piece is unqualified; or when the marking lines are drawn by manual operation, the width of the drawn marking lines may exceed 0.5mm due to different marking pens or correction of the marking lines, so that the experimental error is large, and the method for drawing the marking lines by manual operation is not suitable for measuring the test piece with small slippage. Meanwhile, in the method a, although a suspension device is provided, a suspension form of the suspension device is not specified.

Many attempts have been made to improve the test method for improving the heat resistance of asphalt waterproof coiled materials, so as to reduce experimental errors and improve the precision of test results. For example, CN111487277A discloses an experimental apparatus and a test method for heat resistance of asphalt waterproof coiled material. The experimental device comprises a vertical rod, a sample fixing beam, a clamping piece, a vernier, a gasket and a base. Two groups of upright posts are symmetrically fixed on the base, and scale areas are arranged on the upright posts; the top of each upright rod is integrally connected with the sample fixing beam, the top end of an asphalt waterproof coiled material sample with the width smaller than the distance between the two upright rods is fixed on the sample fixing beam through the gasket, and the bottom end of the sample vertically droops; the position clamping piece includes position clamping piece and lower position clamping piece, the both ends and both sides of position clamping piece are gone up pole setting an organic whole connection, just the lower surface of going up the position clamping piece with the zero scale of pole setting flushes, the both ends of position clamping piece and two sets of down in the pole setting vernier scale an organic whole connection, the vernier scale can be followed the pole setting reciprocates, the upper surface of position clamping piece down with the zero scale of vernier scale flushes. Although the suspension problem in the method A is improved, the problems that the experiment error is large and the heat resistance testing precision is reduced due to the fact that the marking line is drawn through manual operation are not solved.

Therefore, how to provide a testing method to solve the problem of large testing error when manually drawing the marking line has become a technical problem to be solved.
